ECshop 迁移到 PHP7版本时遇到的兼容性问题_php实例
在 PHP7 上安装 ECShop V2.7.3时,报错!
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; ECS has a deprecated constructor in /usr/local/nginx/html/ecshop/upload/includes/cls_ecshop.php on line 25
这个报错的原因是 PHP7 不再支持与类名相同的构造方法,构造方法统一使用 __construct(), 比如下面的写法 PHP7 就会报这个错误。
<?php class foo { function foo() { echo 'I am the constructor'; } } ?>
回到 ecshop 我们看一下 cls_ecshop.php 文件的25行。如下
果然有与类名相同的构造方法,我们将构造方法 ECS 修改为 __construct,
回到 ecshop 的安装首页刷新,发现已经没有错误了。
单击下一步,报错
Deprecated: Non-static method cls_image::gd_version() should not be called statically in /usr/local/nginx/html/ecshop/upload/install/includes/lib_installer.php on line 31
这个报错的原因是静态调用非静态方法,比如下面的代码就会报这个错误
<?php class foo { function bar() { echo 'I am not static!'; } } foo::bar(); ?>
修改方法也很简单,要么将该方法改为静态方法,要么将该调用改为非静态调用。 我们看一下报错的文件 lib_installer.php 的 31行代码
还有cls image类文件的 gd version() 方法,可以看到的确没有使用 static关键字
第一种修改方式,将该方法修改为静态方法,在方法前加关键字 public static
第二种修改方式,采用非静态方式的调用,修改lib_installer.php 的 31行代码
这两种方法都可以解决问题。 回到ecshop的安装步骤第二页,错误提示已经不见了。
再下一步悲剧了,PHP7 不支持原始的 mysql api 了,PHP7 支持更好的 Mysqli API 和 pdo_mysql api 所以 ecshop 不改掉操作 mysql 的 api 是无法在 PHP7 上运行起来了。

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

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

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

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.
