What should I do if the php7.0 zip module is not supported?

With the continuous development and upgrading of programming languages, program development is becoming faster and more efficient. In the PHP field, the launch of PHP7.0 has also brought a faster and more efficient development experience. However, some PHP programmers reported that in PHP7.0, the zip module is no longer supported. This problem troubles some programmers who use the zip module. This article will describe this problem in detail and how to solve it.

The role of the zip module

First, we need to understand the role of the zip module. The zip module is used to package, compress and decompress files. In PHP, through the zip module, you can package multiple files into a compressed file, or decompress a compressed file into multiple files. The function of the zip module is very practical, especially when a large number of files need to be transferred. Multiple files can be merged into one compressed file for transmission to improve transmission efficiency. Therefore, many PHP programmers will use the zip module.

The reason why the zip module is not supported in PHP7.0

In PHP7.0, the zip module is no longer supported. This is because the zlib library of PHP7.0 is different from the zlib of PHP5.x Caused by library incompatibility. The zlib library in PHP7.0 uses the latest version of the zlib library, while the old version of the zlib library is used in PHP5.x. This results in PHP7.0 no longer supporting the old version of the zip module. If you still need to use the zip module in PHP7.0, we must install the new version of the zlib library ourselves and add the -zlib option when compiling PHP.

Solution

If you need to use the zip module in PHP7.0, you can follow the steps below:

1. Download the latest version of the zlib library Version:

   First, you need to download the latest zlib library through the following link: https://www.zlib.net/

2. Installation zlib library

   Next, you need to unzip the downloaded zlib library and install it into your system. The installation process is as follows:

   $ tar -zxvf zlib-1.2.11.tar.gz
   $ cd zlib-1.2.11
   $ ./configure --prefix=/usr/local/zlib
   $ make
   $ make install

   In the above command, --prefix specifies the directory where the zlib library is installed, which can be modified according to your own needs.

3. Change the PHP configuration file

   After installing the zlib library, we need to modify the PHP configuration file to support the zip module. You need to find the php.ini file and add the following two lines in it:

   extension=php_zip.so
   extension_dir=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/

   The first line is to import the zip module, and the second line is to specify the path to import the module, which can be modified according to your own needs.

4. Recompile PHP

   After modifying the configuration file, we need to recompile PHP to make it effective. You need to execute the following command:

   $ ./configure --with-zlib-dir=/usr/local/zlib --with-php-config=/usr/local/php7/bin/php-config
   $ make
   $ make install

   In the above command, --with-zlib-dir specifies the installation path of the zlib library, and --with-php-config specifies the installation path of PHP. The path here needs to be modified according to your actual situation.

Through the above steps, you can use the zip module in PHP7.0. It should be noted that if you did not add the -zlib option when compiling PHP, you need to manually copy the php_zip.so file to the extension directory after compilation and add extension=php_zip.so in php.ini.

Conclusion

Although the zip module is no longer supported in PHP7.0, we can continue to use the zip module in PHP7.0 by installing a new version of the zlib library and recompiling PHP. . These steps may be tedious, but for programmers who need to use the zip module, the problem is worth solving. Hope this article helps with this issue.
