将循环值存储在数组中

Question

I want to store all value in a array and get out from the loop is it possible?

<?php
    $a=array('a', 'b', 'c');
    foreach($a as $b)
    {
        for($i=0; $i<count($a); $i++)
        {
            $c = array();
            $c[$i] = $b;     
        }

        print_r($c);
    }
?>

Answer 1

I made a mistake the array variable $c=array() should be out side of loop

<?php

   $a=array('a','b','c');

   $c=array();
   // for loop
   for($i=0;$i<count($a);$i++){
       $c[$i]=$a[$i];
   }
   // forEach loop
   foreach ($a as $b){
         $c[]=$b;
   }
   // while loop
   $x=0;
   while($x<count($a)){
          $c[$x]=$a[$x];
          $x++;
   }

  print_r($c);
?>
