PHP check a string contains specific value or string

How to check if a string having specific characters or string


In PHP we can check with strpos() . strpos() is the simplest way to get string having search texts or not.


Examples :-
For examle here is a php string and we want to know that it contains "php" word or not.

$a = 'Hello string do u have php word?';

The below line of code echo true if php word exist in string.




if (strpos($a, 'php') !== false) { echo 'true'; } OR

if (strpos($string, $word) === FALSE) { ... not found ... }

We can also use preg_match() to determine that

Example
if (preg_match('/php/',$a)) {
  echo 'true';
}
