Search and Replace

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.

You can download this script as a .txt file. Remember to rename the file as a .php file.

//
// 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
