note 31945 added to function.preg-match

A comprehensive guide on (Perl) regular expressions: [http://www.wdvl.com/Authoring/Languages/Perl/ PerlfortheWeb/pattern_matching.html] I inserted an example below for a search & change (this time not a search & delete as shown lots of time in the other comments). If you want to do a search & change you can use the following example: Say I want to search a html file and change all the direct links to point to a template file with an added variable. The variable would be the original name of the html file (the (\w+) block). It would look like this: $file = "some_file.html"; $search_string = "/(<a href=")(\w+)(\.html)/i"; $replace_string = "\${1}template_file.php?pagename=\$2"; $contents = file($file); foreach ($contents as $line_num => $line) { if (preg_match('/(<a href=")(\w+)(\.html)/i', $line)) { echo ($line_num. " before: ". $line. "<br>"); $line = preg_replace($search_string, $replace_string, $line); echo ($line_num. " after: ". $line. "<br>"); } } Make sure you use double quotes in the $replace_string or the blocks $1 and $2 will not be replaced with the original contents. Add a piece of code that 'walks' all the html files in a directory and you could use it to move entire (static) websites into a database in just one go.
