Description

This class can search for files with a given string using grep.

It can take a given string and performs a search using the grep command on files inside a given directory that may contain that string.

The grep command may take custom options, so it may perform searches on directories recursively.

Certain files specified in a class array variable may be ignored and not be returned in the results.

Searching for the contents of files in PHP is easy. However it can be slow when you need to search for data in many files.

This class provides an alternative that can be faster by using the grep command that is available in most Unix or Linux distributions, so it can search many files at once traversing directories recursively.

SearchStringInDirectory

PHP Search String In Directory

Searching for the contents of files in PHP is easy. However it can be slow when you need to search for data in many files.

This class provides an alternative that can be faster by using the grep command that is available in most Unix or Linux distributions, so it can search many files at once traversing directories recursively.

How to use 1. Require class: require_once 'SearchStringInDirectory.php'; 2. Using: $srch = new SearchStringInDirectory('/path/to/search/folder'); 3. Using: $result $srch->search("Search string");

Example code in 'index.php' file.

Thank you !

I highly appreciate any of your donations.
