To get characters of a string one by one in PHP, you can use a combination of the strlen () and substr () functions. Here's an example:



$str = "Hello World";

for ($i = 0; $i < strlen($str); $i++) {
    echo substr($str, $i, 1) . "<br>";
}

In this example, we define a string variable $str and use a for loop to iterate over the string. The strlen () function returns the length of the string, which is used as the limit for the loop.

Inside the loop, we use the substr () function to extract one character from the string at a time. The first argument of substr () is the string itself, the second argument is the starting index, and the third argument is the length (which is 1 in this case).

Finally, we use echo to output each character of the string on a separate line.

Alternatively, you can also use the str_split () function to split a string into an array of characters and then loop over the array:



$str = "Hello World";

$chars = str_split($str);

foreach ($chars as $char) {
    echo $char . "<br>";
}

This approach splits the string into an array of characters using the str_split() function and then uses a foreach loop to iterate over the array. The $char variable contains one character from the array at a time, which we can output using echo.
