README

WholeTextFinder is a simple whole text finder.

Basic Usage

Use the find method. Here is a basic search:

//..
use Finder\WholeTextFinder;

$haystack  = "PHP PHP is the #1 web scripting PHP language of choice.";
$needle = "php";

// 3 matches
$matches = WholeTextFinder::find($haystack, $needle);

// $matches is equals to:
//
// array(3) {
//    [0] =>
//  array(2) {
//            [0] =>
//    string(3) "PHP"
//            [1] =>
//    int(0)
//  }
//  [1] =>
//  array(2) {
//            [0] =>
//    string(3) "PHP"
//            [1] =>
//    int(4)
//  }
//  [2] =>
//  array(2) {
//            [0] =>
//    string(3) "PHP"
//            [1] =>
//    int(32)
//  }
// }

Multi bytes strings

Please note that WholeTextFinder::find function is multi byte safe and returns the correct word positions in the original phrase. Take a look here:

//..
use Finder\WholeTextFinder;

$haystack  = "La casa è bella bella";
$needle = "bella";

$matches = WholeTextFinder::find($haystack, $needle, true, true, true);

// $matches is equals to:
// array (
//    0 =>
//        array (
//            0 => 'bella',
//            1 => 10,
//        ),
//    1 =>
//        array (
//            0 => 'bella',
//            1 => 16,
//        ),
//)

Find and Replace

There is also available a findAndReplace method:

//..
use Finder\WholeTextFinder;

$haystack = 'Δύο παράγοντες καθόρισαν την αντίληψή μου για την Τενεσί Ουίλιαμς και τη σκηνική παρουσίαση των κειμένων: η Maria Britneva και η Annette Saddik, αφετέρου.';
$needle = 'και';
$replacement = 'test';

$matches = WholeTextFinder::findAndReplace($haystack, $needle, $replacement);

// $matches is equals to:
//
// array(2) {
//   ["replacement"]=>
//   string(252) "Δύο παράγοντες καθόρισαν την αντίληψή μου για την Τενεσί Ουίλιαμς test τη σκηνική παρουσίαση των κειμένων: η Maria Britneva test η Annette Saddik, αφετέρου."
//   ["occurrencies"]=>
//   array(2) {
//     [0]=>
//     array(2) {
//       [0]=>
//       string(6) "και"
//       [1]=>
//       int(66)
//     }
//     [1]=>
//     array(2) {
//       [0]=>
//       string(6) "και"
//       [1]=>
//       int(123)
//     }
//   }
// } 
//

This method will automatically exclude from replace HTML and some Matecat special tags, but allows to replace the inner content inside HTML tags.

So, for example:

//..
use Finder\WholeTextFinder;

// Example 1
$haystack = "Beauty -> 2 Anti-Akne Gesichtsreiniger Schlankmacher <g id=\"2\">XXX</g>";
$needle = 2;
$replacement = "test";

$matches = WholeTextFinder::findAndReplace($haystack, $needle, $replacement);

// $matches is equals to:
//
// array(2) {
//   ["replacement"]=>
//   string(252) "Beauty -> test Anti-Akne Gesichtsreiniger Schlankmacher <g id="2">XXX</g>"
//   ["occurrencies"]=>
//   array(1) {
//    [0]=>
//      array(2) {
//        [0]=>
//        string(1) "2"
//        [1]=>
//        int(10)
//     }
//   }
// } 
//

// Example 2
$haystack = "Beauty -> 2 Anti-Akne Gesichtsreiniger Schlankmacher <g id=\"2\">XXX</g>";
$needle = 'XXX';
$replacement = "test";

$matches = WholeTextFinder::findAndReplace($haystack, $needle, $replacement);

// $matches is equals to:
//
// array(2) {
//   ["replacement"]=>
//   string(252) "Beauty -> 2 Anti-Akne Gesichtsreiniger Schlankmacher <g id="2">test</g>"
//   ["occurrencies"]=>
//   array(1) {
//    [0]=>
//      array(2) {
//        [0]=>
//        string(1) "test"
//        [1]=>
//        int(55)
//     }
//   }
// } 
//

Search options

Some options are avaliable:

You can also specify four options:

• $skipHtmlEntities (true by default)
• $exactMatch (false by default)
• $caseSensitive (false by default)
• $preserveNbsps (false by default)

Here are some examples:

//..
use Finder\WholeTextFinder;

$haystack  = "PHP PHP is the #1 web scripting PHP language of choice.";

// 0 matches
$needle = "php";
$matches = WholeTextFinder::find($haystack, $needle, true, true, true);
   
// 1 match 
$needle = "#1";
$matches = WholeTextFinder::find($haystack, $needle, true, true, true);

// 1 match, even if the haystack contains an invisible nbsp and the needle has an ordinary spacer
$haystackWithNbsp  = "Lawful basis for processing including basis of legitimate interest";
$needleWithoutNbsp = "Lawful basis for processing including basis of legitimate interest";
$matches = WholeTextFinder::find($haystackWithNbsp, $needleWithoutNbsp, true, true, true);
