How to check if string contains specific word in PHP

    RahulBy 1 Min ReadUpdated:

    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 an input string contains another substring in it.

    Here is a sample PHP programme, which will evaluate to true because the main string $str contains the substring ‘TecAdmin‘ in it. This will print “true”.

    <?php
    $str = 'Welcome to Tecadmin';
     
    if (strpos($str, 'Tecadmin') !== false) {
        echo 'true';
    }
    ?>

    Another PHP program will evaluate to false because the main string $str doesn’t contains the substring ‘Hello‘ in it. This will nothing print.
