PHP RegEx: Case Insensitive PHP Script


PHP RegEx: Case Insensitive PHP Script

In previous tutorial we match at the beggining of the string given. But that is a case sensitive. If your condition like this: if(preg_match(“/^ABC/”, $string)) then the value of your string “abc”. The script will returned with this message:

No match found

This is because of case sensitive. But in this script we will make the condition insensitive using regex “i” for insensitive. Shown below:

 

 

    <?php // create a string 
    $string = 'Ronard'; 
    // try to match our pattern 
    if(preg_match("/^ron/i", $string)) { 
    // echo this is it matches 
    echo 'The string begins with Ron'; 
    } else { 
    // if not match is found echo this line 
    echo 'No match found'; } 
    ?>

 

Even if your string given are ROn, rOn, RoN the script will read insensitive and display the message “The string begins with Ron”.
