PHP Code works well in XAMPP but results an error at my webhost

I have a local XAMPP installation for testing and an webserver for live testing. At my local environment, everything works well. But when I load it up to my server, it gives me the error:

Parse error: syntax error, unexpected '[' in /data/web/e36087/html/pdf/index.php on line 11

But everything seems correct. What can I do?

PHP-Code:

<?php

    setlocale(LC_TIME, 'de_DE.UTF-8');

    $xmldb = "db.xml";

    $xml = simplexml_load_file($xmldb);

    if(isset($_POST["remove"])) {

        unlink($xml->xpath('/data//count['.$_POST["remove"].']/fulldir')[0][0]);

        unlink($xml->xpath('/data//count['.$_POST["remove"].']/pdfdir')[0][0].$xml-       >xpath('/data//count['.$_POST["remove"].']/filename')[0][0]);

        $query = $xml->xpath('/data//count['.$_POST["remove"].']')[0][0];

        unset($query[0][0]);
        //Datei schreiben

        $fopen = fopen($xmldb, "w"); 
        fwrite($fopen, $xml->asXML());
        fclose($fopen);

    }

?>

Solution

  • Function array dereferencing was first added in PHP 5.4. It's likely that your host is running 5.3.

    In short this means that 

    unlink( $xml->xpath('/data//count['.$_POST["remove"].']/fulldir')[0][0] );

    must be written as this:

    $path = $xml->xpath('/data//count['.$_POST["remove"].']/fulldir');
unlink( $path[0][0] );

    So essentially, save your method result to a variable before using indexes.
