PHP - iterate on string characters

Question

Is there a nice way to iterate on the characters of a string? I\'d like to be able to do foreach, array_map, array_walk, array_

Answer 1

Iterate string:

for ($i = 0; $i < strlen($str); $i++){
    echo $str[$i];
}

Answer 2

If your strings are in Unicode you should use preg_split with /u modifier

From comments in php documentation:

function mb_str_split( $string ) { 
    # Split at all position not after the start: ^ 
    # and not before the end: $ 
    return preg_split('/(?<!^)(?!$)/u', $string ); 
} 

Answer 3

Step 1: convert the string to an array using the str_split function

$array = str_split($your_string);

Step 2: loop through the newly created array

foreach ($array as $char) {
 echo $char;
}

You can check the PHP docs for more information: str_split
