to determine whether a string contains another string you can use the php function strpos(). int strpos ( string $haystack , mixed $needle [, int $offset = ] ) <?php $haystack = 'how are you'; $needle = 'are'; if (strpos($haystack,$needle) !== false) { echo '$haystack contains $needle'; } ?> caution: if the needle you are  use strpos $haystack = "foo bar baz"; $needle = "bar"; if( strpos( $haystack, $needle ) !== false ) { echo "\"bar\" exists in the haystack variable"; }. in your case: if( strpos( $a, 'some text' ) !== false ) echo 'text';. note that my use of the !== operator (instead of != false or == true or even just if( strpos( ) ) { ) is because of the  mai this tutorial will help you to check if a string contains any substring in php programming language. for example, you want to run a specific line of code only if any input string contains another substring in it. example : the following code will evaluate to true because the string $str contains the

public static function contains(&$haystack, &$needle, &$offset) { $result = strpos($haystack, $needle, $offset); return $result !== false; } intuitive implementation .. if not found returns . public static function strpos(&$haystack, &$needle, &$offset) { $result = strpos($haystack, $needle, $offset); if ($result === false ) there is no php function just to check only _if_ $needle occurs in $haystack; strpos() tells you if it _doesn't_ by returning false, but, if it does occur, it tells you _where_ it occurs as an integer, which is (zero) if $needle is the first part of $haystack, which is why testing if (strpos($needle, $haystack)===false) is the only way to  it impossible to receive false as a return value from in_array using loose checking if your arrays contains both the constants true and false. you might understandably trip over this (or the inverse passing boolean true to check against an array of e.g. nonempty strings), but it's certainly not counter intuitive and makes perfect
