wiping the database doesn't really sound like a good solution to me - and i think my client won't like the idea as well.

So i started writing that php script. I have very limited php skills, but this is what i have for now:

At the moment the str_replace(...) Function doesn't always lead to the correct result, but i'm not sure where that comes from...

<?php
$dbFileName = "dumpTest.sql";
$csvFileName = "TableNames.csv";

repairFile($dbFileName, $csvFileName);

function repairFile($dbFileName, $csvFileName) {
	$sqlFileHandle = fopen($dbFileName, "r");
	$contents = fread($sqlFileHandle, filesize($dbFileName));
	$csvFileHandle = fopen ($csvFileName,"r");              // Datei zum Lesen öffnen
	while ( ($data = fgetcsv ($csvFileHandle, 1000, ";")) !== FALSE ) {
		print $data[0].' -> '.$data[1].'<br>'; 
		$contents = str_replace($data[0], $data[1], $contents, $count);  
		print $count.'<br>';
	}

 	$sqlResultFileHandle = fopen($dbFileName, "w");
	
    if (!fwrite($sqlResultFileHandle, $contents)) {
        print "Can't write File $dbFileName";
        exit;
    }
	fclose($csvFileHandle);
	fclose($sqlFileHandle);
	fclose($sqlResultFileHandle);
}
	unset($contents, $sqlFileHandle, $csvFileHandle);
	unset($GLOBALS['contents'], $GLOBALS['sqlFileHandle'], $GLOBALS['csvFileHandle']);

?>
