Best practice: Import mySQL file in PHP; split queries

Question

I have a situation where I have to update a web site on a shared hosting provider. The site has a CMS. Uploading the CMS\'s files is pretty straightforward using FTP.

I ran into the same problem. I solved it using a regular expression:

function splitQueryText($query) {
    // the regex needs a trailing semicolon
    $query = trim($query);

    if (substr($query, -1) != ";")
        $query .= ";";

    // i spent 3 days figuring out this line
    preg_match_all("/(?>[^;']|(''|(?>'([^']|\\')*[^\\\]')))+;/ixU", $query, $matches, PREG_SET_ORDER);

    $querySplit = "";

    foreach ($matches as $match) {
        // get rid of the trailing semicolon
        $querySplit[] = substr($match[0], 0, -1);
    }

    return $querySplit;
}

$queryList = splitQueryText($inputText);

foreach ($queryList as $query) {
    $result = mysql_query($query);
}
