speeding up a script

[trigger]

I got this script...

require_once('Connections/Connection.php');
mysql_select_db($database_Connection, $Connection);
//first opening of directory to extract filenames, keywords, and descriptions
$dh  = opendir("C:\webfolder");
while (false !== ($filename = readdir($dh))) {	
	if ((preg_match('/htm/', $filename)) || (preg_match('/sun(.*)php/', $filename))){
	$handle = fopen($filename, "rb");
	$tags = get_meta_tags ($filename);
	$description = $tags['description'];
	$keywords =  $tags['keywords'];
	echo "$filename : $description : $keywords \n";
	$buffer = fread($handle, filesize($filename));
	fclose($handle);
	//get the title
	preg_match('#<title>(.*)</title>#isU', $buffer, $match); 
	$title = $match[1];
	echo "$title \n";
	//get the content
	preg_match('#<body(.*)</body>#isU', $buffer, $bodymatch);
	$bodytemp = $bodymatch[1];

//start of function to strip punctuation and tags out
$search = array ("'<script[^>]*?>.*?</script>'si",  // Strip out javascript
             "'<[\/\!]*?[^<>]*?>'si",           // Strip out html tags
             "'([\r\n])[\s]+'",                 // Strip out white space
             "'&(quot|#34);'i",                 // Replace html entities
             "'&(amp|#38);'i",
             "'&(lt|#60);'i",
             "'&(gt|#62);'i",
             "'&(nbsp|#160);'i",
             "'&(iexcl|#161);'i",
             "'&(cent|#162);'i",
             "'&(pound|#163);'i",
             "'&(copy|#169);'i",
             "'&#(\d+);'e");                    // evaluate as php

		$replace = array ("",
              "",
              "\\1",
              "\"",
              "&",
              "<",
              ">",
              " ",
              chr(161),
              chr(162),
              chr(163),
              chr(169),
              "chr(\\1)");

$body1 = preg_replace ($search, $replace, $bodytemp);

$body3 = str_replace('/', '', $body1); 
//end of function
	$body = strip_tags($body3);
	$content = stripslashes($body);
	$content = preg_replace('/[^\w\s]/', '', $content); 
	//$content = preg_replace('/[^A-Za-z0-9_]/', ' ', $bodytemp);
	echo "$content \n\n";				$sqlquery = "INSERT INTO fullsearch (page_id, page_url, page_title, page_description, page_keywords, page_content) 
	VALUES('','$filename', '$title', '$description','$keywords', '$content')";
	echo "FILENAME: $filename\n<br>QUERY: $sqlquery <br>\n";
                $results = mysql_query($sqlquery);
                echo "ERROR: " . mysql_error() ."<br><br><br>\n";	
		}
		else{
		}
}

It times out in the "r"'s of my files, with a fatal exception error because the
Fatal error: Maximum execution time of 30 seconds exceeded
error message. Can I turn that up in my internal php.ini file, or shorten the processing time? I'm running it locally.

It is setting up your arrays for preg_replace with each file. Move that out of the loop it only need to be done once.

You are echoing out an awful lot of text as well, that will slow it down too.

You do an array bassed preg_replace followed by a strreplace. That just doesn't make any sense. You may try using successive preg calls instead of using arrays. It's ugly but it may be quicker.

I really think the biggest speed hit here is coming from the redeclaration or those arrays everytime through the loop though.
