I've adapted my previous solution for multi-dimensional retrieval using
unix directory style path lookup:
function arrayGetValue( &$array, $path, $default=null )
{
$subArray = &$array;
$bits = explode( '/', $path );
foreach( $bits as $aBit )
{
if( isset( $subArray[$aBit] ) )
{
$subArray = &$subArray[$aBit];
}
else
{
unset( $subArray );
$subArray = $default;
break;
}
}
return $subArray;
}
function arrayGetValueProcessed( &$array, $path, $process, $default=null
)
{
return $process( arrayGetValue( $array, $path, $default ) );
}
function cleanser( $value )
{
return mysql_real_escape_string( trim( $value ) ) );
}
//
// Example.
//
$title = arrayGetValueProcessed( $games, $userId.'/favourite/rpg' )
Cheers,
Rob.
