Troubles "porting" cURL from bash to 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).

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',
));

... and yes!!!! :) Can't believe it was that simple :( I thought it was ok to have a "real" array.

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

Nope.. still get just the "302 Found Header"

I added to the question the output I get with the PHP snippet.

I should have tested before answering; my bad.

passing an array results in multipart/form-data content instead of the desired application/x-www-form-urlencoded

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, '', '&');

I tried with curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query($curl_parameters, '', '&')); but still same output (just http header). :(
