Bug description:array_search() should accept a callable as $needle
Description:
------------
It would be really helpful if array_search() would accept a callable as
$needle. There are many instances where it is needed to loop through an
array and stop and the first instance. Currently, the only work around
is to make a function with a foreach() that returns early. This would
bring PHP inline with JavaScript's Array.find() method.
This change would not be a breaking change because array_search() would
continue to work exactly as before the change. The only difference would
be that now $needle can accept a callable that returns a boolean.
This change would also make array_search() more like array_filter().
Test script:
---------------
// Current
function search( $haystack ) {
foreach ( $haystack as $index => $value ) {
if ( $value->id === 3 ) {
return $value;
}
}
return null;
}
$found = search( $haystack );
// Future
$found = array_search( function( $value, $index ) {
return $value->id === 3;
}, $haystack );
