There are 2 different places you can set it:

php.ini

    post_max_size=20M
    upload_max_filesize=20M


.htaccess / httpd.conf / virtualhost include

    php_value post_max_size 20M
    php_value upload_max_filesize 20M

Which one to use depends on what you have access to.

.htaccess will not require a server restart, but php.ini and the other apache conf files will.

I had a situation when variables went missing from POST and all of the above answers didn&#39;t help. It turned out that 

    max_input_vars=1000

was set by default and POST in question had more than that.
This may be a problem.

    ; Maximum allowed size for uploaded files.
    upload_max_filesize = 40M
    
    ; Must be greater than or equal to upload_max_filesize
    post_max_size = 40M


You can do this with .htaccess:

    php_value upload_max_filesize 20M
    php_value post_max_size 20M

We can Increasing the maximum limit using `.htaccess` file.

    php_value session.gc_maxlifetime 10800
    php_value max_input_time         10800
    php_value max_execution_time     10800
    php_value upload_max_filesize    110M
    php_value post_max_size          120M

If sometimes other way are not working, this way is working perfect.

You can increase that in php.ini

    ; Maximum allowed size for uploaded files.
    upload_max_filesize = 2M

You can specify both max post size and max file size limit in php.ini

    post_max_size = 64M
    upload_max_filesize = 64M

I had been facing similar problem in downloading big files this works fine for me now:

    safe_mode = off
    max_input_time = 9000
    memory_limit = 1073741824
    post_max_size = 1073741824
    file_uploads = On
    upload_max_filesize = 1073741824
    max_file_uploads = 100
    allow_url_fopen = On

Hope this helps.




I have a scenario where I need to run *a* linux shell command frequently (with different filenames) from windows. I am using PuTTY and WinSCP to do that (requires login name and password).  The file is copied to a predefined folder in the linux machine through WinSCP and then the command is run from PuTTY. Is there a way by which I can automate this through a program. Ideally I would like to right click the file from windows and issue the command which would copy the file to remote machine and run the predefined command (in PuTTy) with the filename as argument.

Is the following code valid to check if a CPU supports the SSE3 instruction set?

Using the [`IsProcessorFeaturePresent()`][1] function apparently does not work on Windows XP.

    bool CheckSSE3()
    {
        int CPUInfo[4] = {-1};
    
        //-- Get number of valid info ids
        __cpuid(CPUInfo, 0);
        int nIds = CPUInfo[0];
    
        //-- Get info for id &quot;1&quot;
        if (nIds &gt;= 1)
        {
            __cpuid(CPUInfo, 1);
            bool bSSE3NewInstructions = (CPUInfo[2] &amp; 0x1) || false;
            return bSSE3NewInstructions;     
        }
    
        return false;      
    }

I have a form that passes two dates (start and finish) to a PHP script that will add those to a DB. I am having problems validating this. I keep getting the following errors 

**A non well formed numeric value encountered**

This is when I use the following 

    date(&quot;d&quot;,$_GET[&#39;start_date&#39;]);

But when I use the **strtotime()** function as advised by many sites I get a unix timestamp date of 1/1/1970.
Any ideas how I can get the correct date?

A non well formed numeric value encountered

I have a ManyToOne relationship in one of my entities, like so:

    class License {
        // ...
        /**
         * Customer who owns the license
         * 
         * @var \ISE\LicenseManagerBundle\Entity\Customer
         * @ORM\ManyToOne(targetEntity=&quot;Customer&quot;, inversedBy=&quot;licenses&quot;)
         * @ORM\JoinColumn(name=&quot;customer_id&quot;, referencedColumnName=&quot;id&quot;)
         */
        private $customer;
        // ...
    }

    class Customer {
        // ...
        /**
         * Licenses that were at one point generated for the customer
         * 
         * @var \Doctrine\Common\Collections\ArrayCollection
         * @ORM\OneToMany(targetEntity=&quot;License&quot;, mappedBy=&quot;customer&quot;)
         */
        private $licenses;
        // ...
    }

This generates a database schema where the &quot;customer_id&quot; field of the license table is allowed to be null, which is exactly what I do not want.

Here&#39;s some code where I create a record to prove that it indeed allows null values for the reference fields:

    $em = $this-&gt;get(&#39;doctrine&#39;)-&gt;getEntityManager();
    $license = new License();
    // Set some fields - not the reference fields though
    $license-&gt;setValidUntil(new \DateTime(&quot;2012-12-31&quot;));
    $license-&gt;setCreatedAt(new \DateTime());
    // Persist the object
    $em-&gt;persist($license);
    $em-&gt;flush();

Basically, I don&#39;t want a License to be persisted without having a Customer assigned to it. Is there some annotation that needs to be set or should I just require a Customer object to be passed to my License&#39;s constructor?

The database engine I use is MySQL v5.1, and I am using Doctrine 2 in a Symfony2 application.

Doctrine 2 - Disallow null value on foreign keys of ManyToOne relationships

My code is like this:

    if( ($this-&gt;master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) &lt; 0 )
    		
    	{
    	die(&quot;socket_create() failed, reason: &quot;.socket_strerror($this-&gt;master));
    	}

when I run my php file which create connection with web socket, I got error 
Fatal error: Call to undefined function socket_create() in the line 
if( ($this-&gt;master=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) &lt; 0 )


Therefore i am not able to connect web socket and also not able to get response message from socket because Socket Status: 3 (Closed) is displaying in my browser when run client page .

Have you got an idea what is missing?
Thank you in advance.

I have a sql statement in my model,

I then say

 

    $query = $this-&gt;db-&gt;query($sql, array(fields, fields1);
    
    if ($query) {
        return true:
    } else {
        echo &quot;failed&quot;;
        return false;
    }

My query always fails, how do I get php to print the exact sql statement being sent to my database? And display that on my php view, page



How to print SQL statement in codeigniter model

I would like to be able to do something like this:

    class ThingIDs
    {
        const Something = 1;
        const AnotherThing = 2;
    }

    $thing = &#39;Something&#39;;
    $id = ThingIDs::$thing;

This doesn&#39;t work. Is there a straightforward way of doing something equivalent? Note that I&#39;m stuck with the class; it&#39;s in a library I can&#39;t rewrite. I&#39;m writing code that takes arguments on the command line, and I would *really* like it to take symbolic names instead of id numbers.

I&#39;m using the `org.apache.http.HttpResponse` class in my Java application, and I need to be able to get the HTTP status code. If I used `.toString()` on it, I can see the HTTP status code in there. Is there any other function that I can just get the HTTP status code as either an int or String?

Thanks a bunch!

i am getting the error 503 Service Temporarily Unavailable many times in my application
and i want to detect why this error occurs, how ? if there&#39;s a log file or something like that, since i am not familiar with apache.

second thing is that, is it possible to handle this error, that when it occurs apache is restarted ?

I have come to an astonishing conclusion that this:

    Element e = (Element) document.getElementsByTagName(&quot;SomeElementName&quot;).item(0);
    String result = ((Element) e).getTextContent();

Seems to be an incredible 100x faster than this:

    // Accounts for 30%, can be cached
    XPathFactory factory = XPathFactory.newInstance();

    // Negligible
    XPath xpath = factory.newXPath();

    // Negligible
    XPathExpression expression = xpath.compile(&quot;//SomeElementName&quot;);

    // Accounts for 70%
    String result = (String) expression.evaluate(document, XPathConstants.STRING);

I&#39;m using the JVM&#39;s default implementation of JAXP:

    org.apache.xpath.jaxp.XPathFactoryImpl
    org.apache.xpath.jaxp.XPathImpl

I&#39;m really confused, because it&#39;s easy to see how JAXP could optimise the above XPath query to actually execute a simple `getElementsByTagName()` instead. But it doesn&#39;t seem to do that. This problem is limited to around 5-6 frequently used XPath calls, that are abstracted and hidden by an API. Those queries involve simple paths (e.g. `/a/b/c`, no variables, conditions) against an always available DOM Document only. So, if an optimisation can be done, it will be quite easy to achieve.

My question: Is XPath&#39;s slowness an accepted fact, or am I overlooking something? Is there a better (faster) implementation? Or should I just avoid XPath altogether, for simple queries?

I am trying to deploy mod_wsgi with apache to run a django application but I am getting an error 500 internal server error The apache logs shows:


    [Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64] mod_wsgi (pid=16142): Exception occurred processing WSGI script &#39;/home/user/bms/apache/django.wsgi&#39;.

    [Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64] ImportError: No module named django.core.handlers.wsgi

My apache virtual host is as follows:

    &lt;VirtualHost *:80&gt;
    
        DocumentRoot /home/user/bms
    
        &lt;Directory /home/user/bms&gt;
            Order allow,deny
            Allow from all
        &lt;/Directory&gt;
    
    WSGIDaemonProcess bms user=user group=user processes=2 threads=25 python-path=/usr/local/lib/python2.7/site-packages

    
        WSGIProcessGroup bms
    
        WSGIScriptAlias / /home/user/bms/apache/django.wsgi
    
    &lt;/VirtualHost&gt;

And the referenced wsgi file in my app directory with 0777 permissions:

    import os
    import sys
    
    path = &#39;/home/user/bms&#39;
    if path not in sys.path:
        sys.path.append(path)
    
    os.environ[&#39;DJANGO_SETTINGS_MODULE&#39;] = &#39;bms.settings&#39;
    
    import django.core.handlers.wsgi
    application = django.core.handlers.wsgi.WSGIHandler()


I heard that this may be because the apache user does not have the correct permissions. However I have no idea how to fix this. I also tried starting the deamon with the www-data user and this did not solve the issue.

**EDIT**:

I solved this by copying the virtual hosts file into the default one and then disabling the old one with a2dissite. I have no idea how I can do it &quot;properly&quot; and set it so apache goes to the virtual host I want it to though.
