The most common way to compare the two strings is to use "=" to determine whether they are equal. As for the difference between it and "=, simply put, the former emphasizes that the "identical" type also requires the same; the latter requires "equal"

1. Poor Support for Recursion Recursion is a function calling mechanism. This is a powerful feature that can make some complicated things very simple. A recursive example is quick sort ). Unfortunately, PHP is not good at recursion. Zeev, a PHP

Encapsulate process-oriented C or C ++ interfaces for PHP. This refers to process-oriented encapsulation. The purpose of encapsulating PHP extensions is: Because PHP cannot directly use C functions, it needs to use its own memory management and

How can I use PHP to call a function compiled into the so file? One method is to write a PHP module (PhP extension), call the functions in this module in PHP, and then call the functions in so through this module. The following is a simple example.

In PHP, we often use resource type variables. For example, MySQL connection and file handle. These variables cannot be expressed by scalar. How does one link the resource variables in PHP with the resources in C language in the Zend kernel? I. Use
