directory scanning function

-----------------------------------

this function would be especially useful for things like photo galleries or other things that require obtaining all the files in a directory (it uses regular expressions too, so you can get all the files of a specific type or named a certain way, etc etc)

note that this uses eregi so its searches are case insensitive... easily changed by changing it to ereg


//this function is used to scan directories for certain filenames
/*
dir - the directory to scan
filenamepattern - the pattern expression to look for in the file names
empty - what to return if the directory is empty
*/

function scandir ($sdir, $filenamepattern, $empty){
	$filearray=array();
	$scanning = opendir($sdir);

	while (false != ($filename = readdir($scanning))){
		if (eregi($filenamepattern, $filename)){
			$filearray[] = $filename;
		}
	}

	closedir($scanning);
	if (count($filearray)=="0"){
		$filearray[0]=$empty;
	}

	return $filearray;
}

Nice,
Ill use that for the pix display i .....was creating..some time ago..wonder where it is..


Anyways,
You guys know how some sites have 'How many sec it took to generate a page'?


  /* Generated how long it page took to load
     it will display the result in seconds  */

  function utime () { 
      $time = explode( " ", microtime());
	  $usec = (double)$time[0]; 
	  $sec = (double)$time[1]; 
	  return $sec + $usec; 
  } 


	  /* Some variables for the rending time of the page...
	     How long the page took to load                 */
		$generate_start = utime(); 
		$generate_end = utime(); 
		$generate_run = $generate_end - $generate_start; 
		$page_generate = "Page generated in approximately " .  substr($generate_run, 0, 5) . " seconds.";


:D,

1 thing...how do i get the percentage of the PHP and MYSQL Queary it loaded? or w/e?

I.E: (4.06% PHP - 95.94% MySQL)

so you mean like is there any way to find out how much time it spent on sql queries and how much time it spent on parsing actual php? ...

well... I guess you could get the time of loading the page just before you do the query, and then again after you do the query, get the difference (after time - before time) of those and add that value to some total mySQL time variable .... and then for the php time it would be total time of document - mySQL time ...

and then the percents would be easy from there...

I know it might not be the cleanest way to do it... but it's the best way that I can think of (I couldn't find any predefined function that gets the time a query took ... closest was probably mysql_info() which looks like it just gives info about what tables, rows etc were affected or something)

What about the PHP?
Like...the percentage of the PHP loaded on the page...

-----------------------------------

well... assuming there's only mysql and php that you are dealing with do something like totalTime - mysqlTime = phpTime
