Call another php from another domain and get the result - php

Question

I'm trying to call a php from another php passing data to it and getting the return value. The two php's are on different domains.
First php:
$url = 'http://myweb.com/custom-php/createCat.php';
$data = array('name' => $name);
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
echo $result;
Second php (It's on a Wordpress site):
header("Access-Control-Allow-Origin: *");
require('../wp-load.php');
$name = $_REQUEST['name'];
echo $name;
if(isset($name))
{
echo wp_create_category($name,0);
}
else
{
echo false;
}
I get the following error:
file_get_contents(http://myweb.com/custom-php/createCat.php): failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error
But if i access it via http://myweb.com/custom-php/createCat.php?name=test it works ok.

Answer 1

The request error could be because the allow_url_fopen PHP.ini directive is set off in the remote URL.
So an alternative may be using CURL:
<?php
$url = 'http://myweb.com/custom-php/createCat.php';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$result= curl_exec($curl);
curl_close($curl);
?>
Answer to the comment 'how can i send the data i need(a variable with some text)':
Use CURLOPT_POSTFIELDS:
curl_setopt($curl, CURLOPT_POSTFIELDS, "name=test&var=" . urlencode($someText));

When you visit the url you make a get request.
You should do the same in your php:
$url = 'http://myweb.com/custom-php/createCat.php';
$data = array('name' => $name);
$result = file_get_contents($url . '?' . http_build_query($data));
echo $result;
Also, you need to check if the $_REQUEST key is set before using it:
//this header is only required for ajax..
header("Access-Control-Allow-Origin: *");
require('../wp-load.php');
if(isset($_REQUEST['name'];))
{
echo wp_create_category($_REQUEST['name'],0);
}
else
{
echo false;
}
