Reading and executing in .sql in PHP

Had a little problem with not being able to read in SQL in from a file and execute it earlier. Solved the problem, turns out php doesnt like executing more than one line of SQL at once so barfs at the ;. So i have exploded the SQL into an array using the ; as the delimeter.

note: this method wont work with commented SQL

<?php
function _read_file($filename)
	{
	$handle = fopen($filename, 'r');
	$theData = fread($handle, filesize($filename));
	fclose($handle);
	return ($theData);
	}
function  _dbconnect($config) 
		{
		$link = mysql_connect($config['db']['host'], $config['db']['db_user'], $config['db']['db_password']);
		if (!$link) { die('Not connected : ' . mysql_error()); }
		$db_selected = mysql_select_db($config['db']['dbname'], $link);
		if (!$db_selected) { die ('Can\'t use '.$config['db']['dbname'].' : ' . mysql_error()); }		
		}
function _dbupdate ($sql)
		{
		_dbconnect();
		$result = mysql_query($sql);
		if (!$result) {
			die("\n ".'
Invalid query: ' . mysql_error());
					}
		
		}

$sql = _read_file( 'some-sql-file.sql', ';');
$sql = explode(';',$sql);
foreach ($sql as $item)
     {
	if (!empty($item))
		{
		echo "Executing: 
";
		echo '
'.$item.'
';
		_dbupdate($item);
		}
	}
?>
