本文实例讲述了php5.3提示Function ereg() is deprecated Error问题解决方法。分享给大家供大家参考。具体实现方法如下:
一、问题:
PHP 5.3 ereg() 无法正常使用,提示“Function ereg() is deprecated Error”是因为它长ereg 函数进行了升级处理,需要像preg_match使用/ /来规则了,当然也是php5.3把ereg给废掉的节奏了。
PHP 5.3 ereg() 无法正常使用,提示“Function ereg() is deprecated Error”。
问题根源是php中有两种正则表示方法,一个是posix,一个是perl,php6打算废除posix的正则表示方法所以后来就加了个preg_match。此问题解决办法很简单,在ereg前加个过滤提示信息符号即可:把ereg()变成@ereg()。这样屏蔽了提示信息,但根本问题还是没有解决,php在5.2版本以前ereg都使用正常,在5.3以后,就要用preg_match来代替ereg。所以就需要变成这样。
原来:ereg("^[0-9]*$",$page)变成:preg_match("/^[0-9]*$/",$page)
特别提醒:posix与perl的很明显的表达区别就是是否加斜杠,所以与ereg相比,后者在正则的前后分别增加了两个"/"符号,不能缺少。
例如:
改前:
代码如下:
function inject_check($sql_str) {
$sql_str = strtolower($sql_str);
return eregi('fopen|post|eval|select|insert|and|or|update|delete|'|/*|*|../|./|union|into|load_file|outfile', $sql_str); // 进行过滤
}
二、解决方法:
找到代码所在的文件位置:
代码如下:
function inject_check($sql_str) {
$sql_str = strtolower($sql_str);
return preg_match('/fopen|post|eval|select|insert|and|or|update|delete|'|/*|*|../|./|union|into|load_file|outfile/', $sql_str); // 进行过滤
}
注意:一定要加'/'开头与结束。此段参考:http://www.bitsCN.com/article/38857.htm
补充:此问题在php5.2之前版本不会出现。
希望本文所述对大家的PHP程序设计有所帮助。

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
