PHP Class: fast find text (string) in files (recursively)

Scanning your server for specifies phrases
In this post I will present you a PHP class to find a specified text string in files. Files to scan can be grouped in directories and subdirectories because the class uses recursion.

Use case 1: find all files with text "hello", but not "Hello"
include 'FindTxt.php';

$f = new FindTxt;
$f->caseSensitive = true; //find "hello", but not "Hello" (case sensitive search)
$f->formats = array();
$res = $f->find('directory', 'hello');

print_r($res);

Use case 2: find all files with text "hello" but also "Hello"
include 'FindTxt.php';

$f = new FindTxt;
$f->caseSensitive = false; //find "hello" and "Hello" (case insensitive search)
$f->formats = array();
$res = $f->find('directory', 'hello');

print_r($res);

Use case 3: find all files with text "hello" but also "Hello"; ignore GIF, JPEG and PNG files
include 'FindTxt.php';

$f = new FindTxt;
$f->caseSensitive = false; //find "hello" and "Hello" (case insensitive search)
$f->excludeMode = true;
$f->formats = array('.gif', '.jpg', '.jpeg', '.jpe', '.png'); //exclude these files from search
$res = $f->find('directory', 'hello');

print_r($res);

Use case 4: find all .TXT and .XML files with text "hello" but also "Hello"
include 'FindTxt.php';

$f = new FindTxt;
$f->caseSensitive = false; //find "hello" and "Hello" (case insensitive search)
$f->excludeMode = false;
$f->formats = array('.txt', '.xml'); //include only these files in search
$res = $f->find('directory', 'hello');

print_r($res);
