I/O error when parsing many domxml docs

[Joer.]

Hi all,

 

I have a script which if I run more than 50 instances(loop) I get this error or just a blank screen:

 

Warning: domxml_open_file() [function.domxml-open-file]: I/O in /home/eagleboo/public_html/PHP/book.php on line 64

Warning: domxml_open_file() [function.domxml-open-file]: warning : in /home/eagleboo/public_html/PHP/book.php on line 64

Warning: domxml_open_file() [function.domxml-open-file]: failed to load HTTP resource in /home/eagleboo/public_html/PHP/book.php on line 64

Fatal error: Call to a member function on a non-object in /home/eagleboo/public_html/PHP/book.php on line 66 

 

My code is this, I have snipped a ffew things out that shouldnt matter.

 for($i = 0; $i < 60; $i++){
sleep(.9);

$valid[] = checkAmazon($arrayISBN[$i]);

if(strlen($valid[$i]) == 0){
	$gsu[] = $arrayISBN[$i];
}else{
	$countworked++;
}

} 


function checkAmazon($isbn){
$isbn=trim($isbn);
$amazon=*SNIP*
$xml=domxml_open_file($amazon);
$root=$xml->document_element();

$want=array("Author", "Title","TotalNew","TotalUsed", "Amount", "URL");


//Author, ISBN, Title, New Price, Used Price, PicURL
foreach($want as $now){
	$elements=$root->get_elements_by_tagname($now);
	foreach($elements as $element){
		$content=$element->get_content();
		$parentNode=$element->parent_node();
		$parentTag=$parentNode->tagname();

		$xmlResults[]=array("parent"=>$parentTag, "tag"=>$now, "content"=>$content);
	}
}
if(!isset($xmlResults)){
	return false;
}else{
*SNIP*
	}
}

$results['isbn']=$isbn;
             $xml->free();
return $results;
}

} 

 

Not sure what to do in this case.  Does anyone know how to free up memory or resources being used?

[Joer.]

fclose($xml);

 

I tried that but I get an error since im not using fopen.

THere must be some way to clear our the resources used here. I dont need to have them all open while looping through.

 

Just to sum up some of that code for people who dont want to look at it:

 

while loop

  call function checkAmazon

end while

 

function checkAmazon

domxml_open_file()

parse through it

 

end function

 

 

THe problem is it will through a I/O error I think because php has run our of resources from never 'closing' of 'freeing' up those xml docs.

ah

 

I turned off php safe mode on my VPS.  Now it seems to be using free(). 

So that works now I need to figure out why the script is wrong half the time where before it wasnt.
