PHP Linux script operation example: realizing file compression and decompression

In Linux systems, file compression and decompression are frequently used operations. As a powerful server-side programming language, PHP scripts can also be used in the Linux environment to complete file compression and decompression operations. This article will introduce how to use PHP scripts to compress and decompress files, and provide specific code examples.

1. File Compression

First of all, we need to use the compression tools in the Linux system, such as gzip, tar, etc. to achieve file compression. PHP calls these compression tools by executing the command line and integrating them into PHP scripts. Below is an example that shows how to use a PHP script to compress files:

<?php
$fileToCompress = '/path/to/file.txt';
$compressedFile = '/path/to/compressed_file.gz';

$command = 'gzip ' . $fileToCompress . ' > ' . $compressedFile;
exec($command);

if (file_exists($compressedFile)) {
    echo '文件压缩成功';
} else {
    echo '文件压缩失败';
}
?>

In the above example, we have used the exec function to execute the gzip command and compress the file to gz format compressed package. Other compression formats and corresponding command line tools can also be used.

2. File decompression

File decompression is similar to file compression and also needs to be completed using the decompression tool in the Linux system. The PHP script can call the decompression tool by executing the command line and save the decompressed file to the specified location. The following is an example that shows how to use a PHP script to decompress files:

<?php
$compressedFile = '/path/to/compressed_file.gz';
$uncompressedFile = '/path/to/uncompressed_file.txt';

$command = 'gzip -d ' . $compressedFile . ' > ' . $uncompressedFile;
exec($command);

if (file_exists($uncompressedFile)) {
    echo '文件解压成功';
} else {
    echo '文件解压失败';
}
?>

In the above example, we used the gzip -d command to decompress the gz format compressed package and The decompressed file is saved in txt format. Similarly, we can also use other compression formats and corresponding command line tools during decompression operations.

Summary:

This article introduces how to use PHP scripts to implement file compression and decompression operations, and provides specific code examples. By using PHP scripts combined with compression and decompression tools in Linux systems, we can easily compress and decompress files and achieve more efficient file processing. I hope these examples are helpful for your needs in handling files in daily development.
