How to Search and Replace using PHP
Posted: Sun Nov 29, 2009 4:39 am
For when you need to find that variable or string in all your files. Or when you need to change the name of a variable in all your scripts. These Search and Replace scripts operate on all the files of a given type an any directory.
The way the scripts are written you cannot use the # character in the search string (but you can modify the scripts if needed). If you need to use " in the search string or new value string you will need to use \" in the string in the script.
This is the Search Script.
This is the Replace Script.
As always, take a backup before making any changes.

Code: Select all
<?php
// this script will search all the files of a specific type in a specific directory and list those that contain a specific string
//
// enter the string you want to find - it cannot contain the # char or the script will fail
$searchString = "find this";
// enter tha path to the search directory, and the file type to search
$path = "path_to_files/*.htm";
//
// do not change anything below this line
$searchString = "#".$searchString."#";
$globarray = glob($path);
if ($globarray) foreach ($globarray as $filename) {
$source = file_get_contents($filename);
if (preg_match($searchString,$source)) echo "$filename <br>";
$count++;
}
echo "Done - processed $count files";
