File Generator

[Ruggie]

I was having trouble with an upload script that I had and was getting a 502 Bad Gateway error, I wanted to know if it was a filesize problem or a timeout problem.

Finding files on my computer of the right sizes proved to be too annoying so I wrote a quick script that makes files in increments of 1 meg.

It proved very helpful, turns out I was dealing with a timeout issue and not a file size issue, below is the code if anyone else wants to use it!

FYI, was written for windows based systems and was made to be ran from the command line. I did add some <pre> tags incase it was ever ran from a browser.

<?
// Adjust these as you see fit
$start_at_megs = 1; // In Megs, Start at 1 Meg
$end_at_megs = 50; // In Megs, Stop at 100 Megs

set_time_limit(7200); // 2 hours
$fileNames = array();
$fileSizes = array(); // in bytes
// Build Array's
for($i=$start_at_megs;$i<=$end_at_megs;$i++){
	$fileNames[] = $i."MB";
	$fileSizes[] = $i*1024*1024;
}

echo "<pre>\r\n\r\n";$output = "";
if (count($fileNames) == count($fileSizes)){
	$count = count($fileNames);
	for($i=0;$i<$count;$i++){
		$fp = @fopen($fileNames[$i].".txt","x"); // Only create new files, don't overwrite old ones.
		if ($fp != false){
			echo $fileNames[$i].".txt created, filling with data ... ";
			$difference = $fileSizes[$i] - strlen($output);
			for($l=1;$l<=$difference;$l++){
				$output .= "1"; // 1 byte of data
			}
			fwrite($fp,$output);
			echo "done!\r\n";
		}else{
			if ($display_as_html) echo "<br>";
			echo $fileNames[$i].".txt already exists ... skipping!\r\n";
		}
		@fclose($fp);
	}
}else{
	echo "Arrays not the same length! \r\n";
	echo "Exiting...\r\n";
}
echo "\r\n</pre>";
?>

Enjoy!
