Function to return value of an array element taking the array and a key as input

[gkb6891]

PHP has a syntactical issue with a construct like the following:

$value = return_array_fun()[$key];

where return_array_fun() is a function returning an array as output.

One is forced to rewrite it as

$temp_array = return_array_fun();
$value = $temp_array[$key];

It would be nice to have a function in WordPress that makes this simple. Here's the one-liner:

 /**
   * Get the value of an element in an array
   */
  function array_get_value( $array, $key ) {
          return $array[$key];
  }

I didn't create a separate diff file for this.

I don't think you need an accessor function like that, it's too much reflection. Reading values is like 1000x's faster than reading the return value of a function call in PHP. And instead of setting $value = $arr[$key], just refer to it as $arr[$key] unless you act on it by calling trim() or something

Agreed. Maybe I should be talking to the guys at ​php.net project to resolve the syntactic issues. :)

I do believe some recent versions of PHP do allow this but as wonderboymusic said this is sure not preferable.

This is no longer a problem as of PHP 5.4.
