PharData::decompressFiles

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

PharData::decompressFiles — Decompresses all files in the current zip archive

說明

public PharData::decompressFiles(): bool

注意:

此方法需要 將 php.ini 中的 phar.readonly 設為 0 以適合 Phar 對象. 否則, 將拋出PharException.

For tar-based archives, this method throws a BadMethodCallException, as compression of individual files within a tar archive is not supported by the file format. Use PharData::compress() to compress an entire tar-based archive.

For Zip-based archives, this method decompresses all files in the archive. The zlib or bzip2 extensions must be enabled to take advantage of this feature if any files are compressed using bzip2/zlib compression.

參數(shù)

此函數(shù)沒有參數(shù)。

返回值

成功時返回 true， 或者在失敗時返回 false。

錯誤／異常

Throws BadMethodCallException if the zlib extension is not available, or if any files are compressed using bzip2 compression and the bzip2 extension is not enabled.

范例

示例 #1 A PharData::decompressFiles() example

<?php
$p = new PharData('/path/to/my.zip');
$p['myfile.txt'] = 'hi';
$p['myfile2.txt'] = 'hi';
$p->compressFiles(Phar::GZ);
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
$p->decompressFiles();
foreach ($p as $file) {
    var_dump($file->getFileName());
    var_dump($file->isCompressed());
    var_dump($file->isCompressed(Phar::BZ2));
    var_dump($file->isCompressed(Phar::GZ));
}
?>

以上例程會輸出：

string(10) "myfile.txt"
int(4096)
bool(false)
bool(true)
string(11) "myfile2.txt"
int(4096)
bool(false)
bool(true)
string(10) "myfile.txt"
bool(false)
bool(false)
bool(false)
string(11) "myfile2.txt"
bool(false)
bool(false)
bool(false)
