PhpStorm + Xdebug remote debugging froze


I have set PHP debugging with Xdebug on PhpStorm to hit a localhost. Everything works fine with "smart PHP listening" or manual debug run unless I have got to the point where code looks like

$aOptions = array (
        'http' => array (
                'header' => "Content-Type: application/x-www-form-urlencoded\r\n$sBits",
                'method' => 'POST',
                'content' => http_build_query ( $aData )
        )
);

$rContext = stream_context_create ( $aOptions );
$sResult = file_get_contents ( $sUrl, false, $rContext );
return \json_decode ( $sResult );

and got stuck on a line

$sResult = file_get_contents ( $sUrl, false, $rContext );

with an error message

file_get_contents(http://localhost:8888/data/?/Ajax/&q[]=/0/): failed to open stream: HTTP request failed!

but when I run debug after that line will pass all work fine.

PhpStorm and Xdebug has already set

  • Settings | PHP | Debug | Max simultaneous connections --> 5.

xdebug.remote_autostart = 1

Any clue why Xdebug hangs on it when without debugging it can pass w/o any issue?


Solution

  • Based on JetBrains documentation for simultaneous debugging sessions I was able to get it fixed by adding suggested code to start debugger session for child requests as follow

    $aOptions = array (
            'http' => array (
                    'header' => "Content-Type: application/x-www-form-urlencoded\r\n$sBits",
                    'method' => 'POST',
                    'content' => http_build_query ( $aData )
            )
    );
    
    $debuggingQuerystring = '';
    if (isset($_GET['XDEBUG_SESSION_START'])) { // xdebug
         $debuggingQuerystring = '?XDEBUG_SESSION_START=' . $_GET['XDEBUG_SESSION_START'];
    }
    if (isset($_COOKIE['XDEBUG_SESSION'])) { // xdebug (cookie)
         $debuggingQuerystring = '?XDEBUG_SESSION_START=PHPSTORM';
    }
    
    $rContext = stream_context_create ( $aOptions );
    $sResult = file_get_contents ( $sUrl.$debuggingQuerystring, false, $rContext );
    return \json_decode ( $sResult );
