7 hook_module_implements_alter(&$implementations, $hook)

Alter the registry of modules implementing a hook.

This hook is invoked during module_implements(). A module may implement this hook in order to reorder the implementing modules, which are otherwise ordered by the module's system weight.

Parameters

&$implementations An array keyed by the module's name. The value of each item corresponds to a $group, which is usually FALSE, unless the implementation is in a file named $module.$group.inc.

$hook The name of the module hook being implemented.

<?php
function hook_module_implements_alter(&$implementations, $hook) {

    // Move my_module_rdf_mapping() to the end of the list. module_implements()
    // iterates through $implementations with a foreach loop which PHP iterates
    // in the order that the items were added, so to move an item to the end of
    // the array, we remove it and then add it.
    $group = $implementations['my_module'];
    unset($implementations['my_module']);
    $implementations['my_module'] = $group;
