how can i use python's like "For loop" in php to reverse string? -

here python code:

def is_palindrome(s):     return revers(s) == s  def revers(s):     ret = ''     ch in s:         ret = ch + ret     return ret  print is_palindrome('racecar')  # print true 

when convert function php.

function is_palindrome($string){     if (strrev($string) == $string) return true;     return false; } $word = "racecar"; var_dump(is_palindrome($word)); // true  

both functions works fine but, how can revers string php in loop ??

$string = str_split(hello); $output = ''; foreach($string $c){         $output .= $c; } print $output; // output  hello  //i did this, 

that's work find there way in better way ? $string = "hello"; $lent = strlen($string);

$ret = ''; for($i = $lent; ($i > 0) or ($i == 0); $i--) {     $ret .= $string[$i];     #$lent = $lent - 1; }  print $output; //output  olleh 

replace

$output .= $c; 

with

$output = $c . $output;
