This PHP ArrayReplace function allows you to change the PHP array value using an array key or value.



I recently came across this issue in my project, where I need to replace PHP array value by array key.

Here's the PHP ArrayReplace function I wrote to take care of this significant task.

Example:

<?php

function ArrayReplace($Array, $Find, $Replace){
      if(is_array($Array)){
            foreach($Array as $Key=>$Val) {
                  if(is_array($Array[$Key])){
                        $Array[$Key] = ArrayReplace($Array[$Key], $Find, $Replace);
                  }else{
                        if($Key === $Find) {
                           $Array[$Key] = $Replace;
                        }
                  }
            }
      }
      return $Array;
}

//Define Array
$Array = array('FirstName'=>"Alex",'DOB'=>'1985-06-12');
echo '<pre>',print_r($Array,1),'</pre>';

//Replace in Array
$Array = ArrayReplace($Array,'DOB',date('j \of\ F Y',strtotime($Array['DOB'])));
echo '<pre>',print_r($Array,1),'</pre>';

?>

I recently came across this issue when having to deal with a multidimensional array that I needed to have scrubbed for certain values. Here in the above example, I have replaced DOB value in the array by using the array key.

Program Output:

Array
(
   [FirstName] => Alex
   [DOB] => 1985-06-12
)

Array
(
   [FirstName] => Alex
   [DOB] => 12 of June 1985
)

After minor modification, you can also use this function to replace it by value.
