How to Check If a String Contains a Specific Word in PHP

Topic: JavaScript / jQueryPrev|Next

Answer: Use the PHP strpos() Function

You can use the PHP strpos() function to check whether a string contains a specific word or not.

The strpos() function returns the position of the first occurrence of a substring in a string. If the substring is not found it returns false. Also note that string positions start at 0, and not 1.

Let's check out an example to understand how this function basically works:

  • <?php
  • $word = "fox";
  • $mystring = "The quick brown fox jumps over the lazy dog";
  •  
  • // Test if string contains the word 
  • if(strpos($mystring, $word) !== false){
  •     echo "Word Found!";
  • } else{
  •     echo "Word Not Found!";
  • }
  • ?>
