Single Action Hooks – Multiple Execution

After you custom action hook is significantly defined and made public, it can be implemented by any developer using several plugins. If there are two or more In situations where more than two developers implement the same hook in their plugins, priority of the actions are of prime concern.

Consider the following code where two plugins implement the same action.

function wpr1_after_post_title() {
// Plugin 1
function wpr2_after_post_title() {
// Plugin 2

In such scenarios, it is better to prioritise your Action Hooks with values so that precedence of other actions can be adjusted accordingly.
