PHP str_contains()

The str_contains() function performs a case sensitive search for a given substring within a string. Checking for the presence of an empty string will always return a positive result.

Syntax

str_contains($aString, $aSubstring)

• $aString: The string to be searched.
• $aSubstring: The substring to be found.

Example

The following example demonstrates the case sensitive nature of str_contains().

<?php
    $sentence = "I love New York";
    $word = "new";

    if(str_contains($sentence, $word)) {
        echo $word." found.";
    }

    $word = "New";
    if(str_contains($sentence, $word)) {
        echo $word." found.";
    }
?>
