I am getting expected notices and warnings and would like to turn them off in my PHP file. The error is:
Warning: fsockopen()
And the notice are:
Notice: A non well formed numeric value encountered in
I am planning to use cron for this PHP script and do not want to get any errors or notices logged anywhere.

Solution 1 - Php
When you are sure your script is perfectly working, you can get rid of warning and notices like this: Put this line at the beginning of your PHP script:
error_reporting(E_ERROR);
Before that, when working on your script, I would advise you to properly debug your script so that all notice or warning disappear one by one.
So you should first set it as verbose as possible with:
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
UPDATE: how to log errors instead of displaying them
As suggested in the comments, the better solution is to log errors into a file so only the PHP developer sees the error messages, not the users.
A possible implementation is via the .htaccess file, useful if you don't have access to the php.ini file (source).
# Suppress PHP errors
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0
# Enable PHP error logging
php_flag log_errors on
php_value error_log /home/path/public_html/domain/PHP_errors.log
# Prevent access to PHP error log
<Files PHP_errors.log>
Order allow,deny
Deny from all
Satisfy All
</Files>
Solution 2 - Php
Prepend functions with the '@' symbol to suppress certain errors, as opposed to turning off all error reporting.
More information: http://php.net/manual/en/language.operators.errorcontrol.php
> PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.
@fsockopen();
Solution 3 - Php
Always show errors on a testing server. Never show errors on a production server.
Write a script to determine whether the page is on a local, testing, or live server, and set $state to "local", "testing", or "live". Then:
if( $state == "local" || $state == "testing" )
{
ini_set( "display_errors", "1" );
error_reporting( E_ALL & ~E_NOTICE );
}
else
{
error_reporting( 0 );
}
Solution 4 - Php
PHP error_reporting reference:
// Turn off all error reporting
error_reporting(0);
// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);
// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);
// Report all PHP errors (see changelog)
error_reporting(E_ALL);
// Report all PHP errors
error_reporting(-1);
// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
Solution 5 - Php
You can set the type of error reporting you need in php.ini or by using the error_reporting() function on top of your script.
Solution 6 - Php
If you can't get to your php.ini file for some reason, disable errors to stdout (display_errors) in a .htaccess file in any directory by adding the following line:
php_flag display_errors off
additionally, you can add error logging to a file:
php_flag log_errors on
