Exploding

[DamienGiles]

Hi,

You know when you can't find a simple solution without creating lines of code?

Well this is it - can someone suggest a simple, clean way of doing it.

$Config = array(
  'system' => array(
    'memory' => array(
      'maxmemory' => 16
    )
  )
);

$Query = "system.memory.maxmemory"; 

I want to find if $Query is going in $Config?

foreach ( explode( '.', $query ) as $test ) {
    if ( !isset( $tmp_config ) ) $tmp_config =& $global_config;
    if ( !isset( $tmp_config[ $test ] ) ) {
        $reached = false; break;
    }

    $tmp_config =& $tmp_config[ $test ];
    $reached = true;
}

if ( $reached === true ) echo 'For config?';
