Loop Through Two Dimensional Array

[Isityou]

I have a two dimensional array that contains data. I want to loop through the two dimensional array and sanitize each element with htmlentities(), how would I go about doing that?

Use nested while/for loops.

 

$i = 0;
while($arr = $array[$i]){
$j = 0;
while($nextarr = $arr[$j]){
//operate on value here
$j++;
}
$i++;
}

ya can take lots of different ways.

$td = array(
  array('%','&'),
  array('<','>'),
  array(5,6)
);

 

the simplest is using foreach 2 levels

foreach($td as $key => $sd)
{
   foreach($sd as $key => $item)
   {
      $sd[$key]=htmlentities($item);
  }
}

Thanks  . I nested foreach loops as you showed me.

try

<?php
function my_h(&$a){$a = htmlentities($a);}
$td = array(
  array('%','&'),
  array('<','>'),
  array(5,6)
);
array_walk_recursive($td, 'my_h');
print_r($td);
?>
