Compatibility issues encountered when migrating ECshop to PHP7 version

When installing ECShop V2.7.3 on PHP7, an error occurred!

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

The reason for this error is that PHP7 no longer supports the constructor method with the same name as the class. The constructor method uniformly uses __construct(). For example, if the following writing method is used, PHP7 will report this error.

<&#63;php 
class foo { 
function foo() {
echo 'I am the constructor';
}
}
&#63;>

Back to ecshop Let’s take a look at line 25 of the cls_ecshop.php file. As shown below

Sure enough, there is a constructor method with the same name as the class. We changed the constructor method ECS to __construct,

Go back to the ecshop installation homepage and refresh it, and find that there are no errors anymore.

Click next and report an error

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

The reason for this error is that the non-static method is statically called. For example, the following code will report this error

<&#63;php 
class foo { 
function bar() {
echo 'I am not static!';
}
}
foo::bar(); 
&#63;>

The modification method is also very simple, or change the method to a static method, Either change the call to a non-static call. Let’s take a look at the 31 lines of code of the error file lib_installer.php

and the gd version() method of the cls image class file. We can see that the static keyword is indeed not used

The first type Modification method, modify the method to a static method, add the keyword public static

in front of the method. The second modification method is to use non-static calling and modify the 31 lines of code of lib_installer.php

Both methods can solve the problem. Returning to the second page of the ecshop installation steps, the error message has disappeared.

The next tragedy is that PHP7 does not support the original mysql api. PHP7 supports better Mysqli API and pdo_mysql api, so ecshop cannot run on PHP7 without changing the api that operates mysql.

OneAPM for PHP can go deep into all PHP applications to complete application performance management and monitoring, including visibility of code-level performance issues and rapid identification and tracing of performance bottlenecks. , real user experience monitoring, server monitoring and end-to-end application performance management.

The above has shared with you the compatibility issues encountered when ECshop migrated to the PHP7 version. I hope it will be helpful to everyone.
