How to Check If a String Contains a Specific Word in PHP? To get this you can use afunction named strpos()  to check if a string contains a specific word or not. PHP strpos() function returns the position of the first substring in a string

<?php

$my_word = "track";

$my_string = "Aspiring champion race car Lightning McQueen

is on the fast track to success, fame, and everything he's ever hoped for";



// Test if string contains the word 

if(strpos($my_string, $my_word) !== false){

echo "Word Found in string!";

} else{

echo "Word Not Found in string!";

}

?>

Simply, using preg_match(), you can add many different words in the pattern, just use this separator " | " (without quotes) between words.

<?php
$my_string = "Aspiring champion race car Lightning McQueen

  is on the fast track to success, fame, and everything he's ever hoped for";


if (preg_match("/race|fame|ever/", $my_string))

  {

  echo "words was matched";

  }

  else echo "not fund";

  ?>
