How to use PHP ZipArchive to filter and search files in compressed packages?
Overview
In web development, we often need to process compressed package files, including filtering and searching. PHP provides the ZipArchive extension, which allows us to easily operate on compressed packages. This article will teach you how to use the PHP ZipArchive extension to filter and search compressed archive files.
Steps
$zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { // 成功打开压缩包文件 } else { // 打开压缩包文件失败 }
$fileContent = $zip->getFromName('example.txt');
$index = $zip->locateName('*.txt');
$zip->extractTo('/path/to/extract/');
Complete example
The following is a complete sample code that demonstrates how to use PHP ZipArchive to filter and search compressed package files.
$zip = new ZipArchive; if ($zip->open('test.zip') === TRUE) { $fileContent = $zip->getFromName('example.txt'); $index = $zip->locateName('*.txt'); if ($index !== false) { $extractDir = '/path/to/extract/'; for($i = 0; $i < $zip->numFiles; $i++) { $fileName = $zip->getNameIndex($i); if(preg_match('/.txt$/', $fileName)) { // 过滤出.txt文件 $zip->extractTo($extractDir, $fileName); } } } $zip->close(); } else { echo '打开压缩包文件失败'; }
Summary
This article introduces how to use PHP ZipArchive to implement filtering and search functions for compressed package files. Through a series of methods of ZipArchive, we can easily open, read, search and extract compressed archive files.
