Troubles "porting" cURL from bash to PHP - php

Question

I'm trying to port this command to PHP:
curl -i -X POST http://website.com \
-H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8" \
-H "Accept: Application/json" \
-H "X-Requested-With: XMLHttpRequest" --data "var1=output1&var2=output2"
From bash it works.. I get this JSON output.
This is what I wrote in PHP to try to get the same result:
<?php
function blabla() {
$curl_parameters = array(
'var1' => "output1",
'var2' => "output2",
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://website.com");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_HEADER,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query( $curl_parameters ));
curl_setopt($ch,CURLOPT_HTTPHEADER,array (
"Content-Type" => "application/x-www-form-urlencoded; charset=UTF-8",
"Accept" => "Application/json",
"X-Requested-With" => "XMLHttpRequest",
));
$output=curl_exec($ch);
curl_close($ch);
}
echo blabla();
?>
Unfortunately with this snippet I just get a 302 Found HTTP header as output (this).. seems like the variables are not passed (the --data part from the bash command).

Answer 1

The problem is with your CURLOPT_HTTPHEADER. It should be an array of strings like this:
curl_setopt($ch,CURLOPT_HTTPHEADER,array(
'Content-Type: application/x-www-form-urlencoded; charset=UTF-8',
'Accept: application/json',
'X-Requested-With: XMLHttpRequest',
));

Answer 2

How about just curl_setopt($ch,CURLOPT_POSTFIELDS, $curl_parameters);? I don't think you need to call http_build_query.

Answer 3

Try add curl follow 302 redirect
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
Also make sure your http_build_query() function uses "&" as argument separator. On some PHP configurations it may be "& amp;" by default
$query = http_build_query($data, '', '&');
