How to Iterate over Characters in String in PHP ?

To iterate over characters in a string in PHP, you can use a for loop or the str_split function to convert the string into an array of characters.

In this example,

We create a string named $str with a value of "PHP".
We use a for loop with an index variable $i to iterate over the string length.
Within the loop, we access each character using $str[$i].
Finally, we print each character.

<?php
$str = 'PHP';
for ($i = 0; $i < strlen($str); $i++) {
    echo $str[$i] . "\n";
}
?>
