What if php _ _ autoload fails?

Failure reason of PHP function _ _ autoload (related to smarty)

The PHP function _ _ autoload can achieve simple automatic loading, but after the introduction of smarty, it is found that the _ _ autoload function is invalid, which is later found to be the cause of the spl_autoload_register function.

Execute the following code:

Function _ _ autoload ($name) {require 'class/'.$name.'.php';echo' 1percent;} function autoload_test ($name) {echo '2percent;} spl_autoload_register (' autoload_test'); $ca=new Ca ()

Result output 2, you can see that the _ _ autoload function is not executed. The parsing on the official website is: if the _ _ autoload () function has been implemented in your program, it must be explicitly registered in the _ _ autoload () queue. Because the spl_autoload_register () function replaces the _ _ autoload () function in Zend Engine with spl_autoload () or spl_autoload_call ().

In order for the code to work properly, you should re-register the _ _ autoload function:

Function _ _ autoload ($name) {require 'class/'.$name.'.php';echo' 1century;} function autoload_test ($name) {echo '2customers;} spl_autoload_register (' autoload_test'); spl_autoload_register ('_ autoload'); $ca=new Ca (); at this point, the study of "what to do with the failure of _ _ autoload in php" is over, hoping to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
