Default HTML Catalog Cleaner - Removes excess white space

This script acts like a one time {strip} tag, removing all unnecessary white spaces from your .html files generated by the HTML Catalog, thus reducing the bandwidth needed for these files.

At the moment, I don't have a .tpl interface written for it, so you have to call it from your browser. This works on your existing catalog, though I am sure you could pull out the regex code and stick it into admin/html_catalog.php if your so inclined.

Here is the code. Put it in whatever directory you wish under whatever name you wish (.php extension of course)...
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>HTML Catalog Cleaner</title> </head> <body> <?php ###################################################### ## ## HTML Catalog Cleaner ## ## ###################################################### ## ## ## Strips every file in the HTML catalog directory ## ## of all excess white spaces. ## ###################################################### ## Version: 1.0.0 (6/26/2004) ## Last updated: 1.0.4 6/26/2004 # Function to Clean-up # ######################## function script_shutdown() { ini_set('max_execution_time', '30'); // Reset the maximum execution time. ini_set('max_input_time', '60'); // Reset the maximum input time. ob_implicit_flush(0); // Data should be kept in the buffer until ready. } register_shutdown_function('script_shutdown'); // Register the shutdown function. # Modify PHP Settings # ####################### ini_set('max_execution_time', '14400'); // Make the maximum execution/input time 4 hours so that the script doesn't time-out. ini_set('max_input_time', '14400'); ini_set('zlib.output_compression_level', 'Off'); // Turn off zlib compression, if On, to prevent Mozilla output problems. ob_implicit_flush(1); // Show the progress in the browser. echo "Stripping the HTML files of excess spaces... "; # Initialize variables. $dir = '/home/your-site-dir/path-to-xcart/catalog'; // Set the absolute directory path. $successes = 0; $failures = 0; $filesize['init'] = 0; $filesize['final'] = 0; $cnt['tmp'] = 0; // Newline counter $cnt['tot'] = 0; // Totals counter $pblr = 0; // Progress bar length reducer # Initialize settings. $regex = array(''=>'/[\t\n\r\f]+/', // Newlines and tabs ' '=>'/ +/', // Excess spaces ''=>'/ /i', // Additional space after non-breaking space '><'=>'/> </' // Space between HTML tags ); # Open the directory and store the file list. if (is_dir($dir)) { if ($dh = opendir($dir)) { # Iterate over file list. while (($filename = readdir($dh)) !== false) { // Use instead of scandir to skip some files. if (strpos($filename,'.htm') !== false) $file_list[] = $filename; } closedir($dh); // Close the directory. } # Perform specific operations on the files. foreach ($file_list as $file) { if (($fs_tmp = filesize($dir.DIRECTORY_SEPARATOR.$file)) !== false) $filesize['init'] += $fs_tmp; $file_contents = file_get_contents($dir.DIRECTORY_SEPARATOR.$file); foreach ($regex as $replace=>$finds) // Do each replacement. $file_contents = preg_replace($finds,$replace,$file_contents); $fp = fopen($dir.DIRECTORY_SEPARATOR.$file, 'w'); // Truncate file, then apply the modifications. if (!fwrite($fp,$file_contents)) { $failure_list[] = $file; // Log failures. $failures++; } else { $successes++; } fclose($fp); if (($fs_tmp = filesize($dir.DIRECTORY_SEPARATOR.$file)) !== false) $filesize['final'] += $fs_tmp; if ($pblr == 5) { // Modify this number to reduce the length of progress bar in case of a lot of files. echo '|'; // Show progess line. $cnt['tmp']++; // Increment the newline counter. $pblr = 0; // Reset pblr counter. } else { $pblr++; } $cnt['tot']++; // Increment totals counter. if ($cnt['tmp']==300) { echo ' '; $cnt['tmp']=0; } // Reset the counter. } } else die(''.$dir.' is not a directory!'); echo ' There were '.number_format($successes).' successful cleanings and '.number_format($failures).' failures out of a total of '.number_format($cnt['tot']).' files.</p>'; echo ' Your HTML Catalog files initially occupied '.number_format($filesize['init']).' bytes of disk space.'; echo ' They now occupy '.number_format($filesize['final']).' bytes of disk space.</p>'; if (isset($failure_list)) { echo ' The following files could not be written: '; foreach ($failure_list as $fail) echo ''.$fail.' '; } ?> </body> </html>

Let me know if you find any problems!

Code:
# Initialize variables. $dir = '/home/your-site-dir/path-to-xcart/catalog'; // Set the absolute
Don't forget to set the path to your html catalog!

I'm testing now!

The code is cleaned up although the reported initial and finished file size for the work is the same.

Pages are lightning quick.

This is a SICK SICK mod. I love it.

I just added it as a link under my HTML Catalog link in the menu admin.

I had already done the once over with this mod on our catalog, when at the last second I decided to add the 'filesize difference' code before posting so I never even saw the output.

I am suprised that there was no difference in filesize. I wonder why not....hmmm.

By the way adpboss, did you make use of those regular expressions I posted for adding {literal} tags to every space and newline in your plain text emails? I have not gotten a chance to actually test it, but I will be doing so soon as I need plain text labels to print.

Am thinking about writing a customizable mod to allow printing on sheets of Avery style labels.

Found a bug, it kills this javascript that I have in my product pages that pops up a new window for detailed images.

So I can't use it as-is, but hopefully I'll find time to play with this and get it to work.

Is there a way to PREVENT areas of code from being touched?

Code:
{literal} <SCRIPT language=JavaScript1.2> <!-- var store_language='{/literal}{$store_language}{literal}'; function product_option(name_of_option) { {/literal} for(i=0; i<{$product_options_count|default:"0"}; i++) if (document.orderform[i].name.search(name_of_option) != -1) return document.orderform[i]; return -1; {literal} } function FormValidation() { {/literal} {if $javascript_code} {$javascript_code} {else} return true; {/if} {literal} } --> </SCRIPT>

Here is the revised version. This should take care of the javascript problem.

Script still kills Javascript and hangs.

I ran it four times tonight and everytime it ran for more than 15 minutes when eventually I had to stop it.

I am going to be redoing our HTML catalog soon. I will have to work on it then.

Not sure what is wrong though.
