How to divide a string into N equal parts with PHP

Answer 1

function DivideStringIntoEqualParts($str, $parts) {
    $length = strlen($str);
    
    if ($length % $parts != 0) {
        echo "No equal parts";
        return NULL;
    }
    
    $j = 0;
    $part_size = (int)($length / $parts);
    $parts_arr = array_fill(0, $parts, NULL);
    
    for ($i = 0; $i < $length; $i = $i + $part_size) {
        $parts_arr[$j] = substr($str, $i, $i + $part_size - $i);
        $j++;
    }
    
    return $parts_arr;
}

$str = "php java c++ c python c#";
$parts = 4;

$parts_arr = DivideStringIntoEqualParts($str, $parts);

for ($i = 0; $i < count($parts_arr); $i++) {
    echo $parts_arr[$i],"\n";
}
