zip_entry_read() memory problem

[gotornot]

Hi

 

Really racking my brain on what i need to do here:

 

I am using the file reader and ned to know how i clear the memory out so that i can re-use it.

$zip = zip_open("$file_name");
if ($zip){
	while ($zip_entry = zip_read($zip)){
	$zip_size = 0;
	$zip_size =  zip_entry_filesize($zip_entry);
	echo ' '.$zip_size.'<br>';
		if (zip_entry_open($zip, $zip_entry)){
			$contents = zip_entry_read($zip_entry, $zip_size);
			$datapool = $contents;
			// now loop through and explode it and add it
			$lines = explode("\n", $datapool); // note you might have to do \r\n else you'll end up with the dummy character in teh last item of the row
			foreach($lines as $value){
				$pieces2 = explode(",", $value);
				// assign the array values ready for check and input
				$mer_id = $pieces2[0];
				$name = $pieces2[1];
				$aw_id = $pieces2[2];	
				$prod_name = $pieces2[3];
				$cats = $pieces2[4];
				$deeplink = $pieces2[5];
				$image = $pieces2[6];
				$fee = $pieces2[7];
				$delivery = $pieces2[8];
				$stock = $pieces2[9];
				$rrp = $pieces2[10];
				$valid_to = $pieces2[11];
				$details = 'This is where we would have lots of content and all the details about the merchants and product etc';
				//$details = $pieces[7];
				//now check that the email hasnt been entered before with a duplicate
				if($fee>"0.01"){
					$q = "SELECT * FROM $tablename WHERE aw_id='$aw_id'";
					$qr = mysql_query($q);
					$qrn = mysql_num_rows($qr);
						if($qrn<"1"){
						//new products
						$i = ++$i;
						$insq = "INSERT INTO $tablename 
						(name, aw_img, aw_deeplink, prod_name, cat, fee, aw_id, mer_id, delivery, in_stock, valid_to, rrp, details, last_update) 
						VALUES 
						('$name', '$image', '$deeplink', '$prod_name', '$cats', '$fee', '$aw_id', '$mer_id', '$delivery', '$stock', '$valid_to', '$rrp', '$details', '$timestamp')";
						$insr = mysql_query($insq);
						}else{
						//its a dupe
						$ud = "UPDATE $tablename SET name='$name', aw_img='$image', aw_deeplink='$deeplink', prod_name='$prod_name', cat='$cats', fee='$fee', aw_id='$aw_id', mer_id='$mer_id', delivery='$delivery', in_stock='$stock', valid_to='$valid_to', rrp='$rrp', details='$details', last_update='$timestamp' WHERE aw_id='$aw_id'";
						$udr = mysql_query($ud);
						$b = ++$b;
						}
					}else{
					$ig = ++$ig;
					}
				}
			zip_entry_close($zip_entry);
			}
		}
	zip_close($zip);
	//delete zip file
	unlink($file_name);
}

 

this gives this output:

 

Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 7136978 bytes) in /web/public_html/zip.php on line 39

 

How do i empty out the memory as basically it needs it as im looping ??
