ProvenExpert - Einfügen des PHP Codes - HILFE

Hallöchen,

ich habe mal eine Frage. Wir haben uns bei ProvenExpert angemeldet und würden sehr gern das GoogleSnippet verwenden, nun soll es laut ProvenExpert auf alle Kategorie PHP Seiten eingefügt werden damit wir bei Google auch die netten Sternchen erhalten.
Leider wissen wir nicht wo genau wir die Dateien finden wo dieser Code rein soll...


Folgenden Code soll in die Kategorien PHP Dateien eingetragen werden:

Code:

<?php

$cacheFile = '/provenexpert_xxxxx.json';
$cachePath = dirname($_SERVER['SCRIPT_FILENAME']) . $cacheFile;
$cachingTime = 3600; // in seconds
$scriptVersion = '1.7';


if (! file_exists($cachePath)) {
    @touch($cachePath, $cachingTime);
    @chmod($cachePath, 0666);
}

// check if user ca write the cache file, otherwise use the system temp directory
if (! is_writable($cachePath)) {
    $cachePath = sys_get_temp_dir() . $cacheFile;

    if (! file_exists($cachePath)) {
        @touch($cachePath, $cachingTime);
        @chmod($cachePath, 0666);
    }
}

    try {
