how to convert object into string in php
Actually i am dealing with web service APIs.i want to use output of one API as a input for another API. when i am trying to do this i got error like this:Catchable fatal error: Object of class std could not be converted to string in C:\ ...
this is the output of first API::stdClass Object ( [document_number] => 10ba60 ) now i want only that number to use as input for 2nd AP
print_r and _string() both are not working in my case
Php Solutions
Solution 1 - Php
You can tailor how your object is represented as a string by implementing a __toString() method in your class, so that when your object is type cast as a string (explicit type cast $str = (string) $myObject;, or automatic echo $myObject) you can control what is included and the string format.
If you only want to display your object's data, the method above would work. If you want to store your object in a session or database, you need to serialize it, so PHP knows how to reconstruct your instance.
Some code to demonstrate the difference:
class MyObject {
protected $name = 'JJ';
public function __toString() {
return "My name is: {$this->name}\n";
}
}
$obj = new MyObject;
echo $obj;
echo serialize($obj);
Output:
> My name is: JJ > > O:8:"MyObject":1:{s:7:"*name";s:2:"JJ";}
Solution 2 - Php
Use the casting operator (string)$yourObject;
Solution 3 - Php
You have the print_r function, check docs.
Solution 4 - Php
There is an object serialization module, with the serialize function you can serialize any object.
Solution 5 - Php
In your case, you should simply use
$firstapiOutput->document_number
as the input for the second api.
