PHP Decompression tar.gz Format file method,

This article describes the PHP method of extracting tar.gz format files. Share to everyone for your reference, as follows:

1, the use of PHP self-compression and archiving extension (Phar)

$phar = new Phardata (' song.tar.gz ');//The path to extract the file is overwritten $phar->extractto (' c:/tmp ', NULL, true);

2, first need to install Pear class management tools

Linux under

/usr/local/php/bin/pear Install Archive_tar

Wamp default is not installed pear, go-pear.php suitable for the old version, php5.3 need to download Go-pear.phar

Put the downloaded file in the PHP directory (any directory can) execute the PHP go-pear.phar command, according to the prompt to press ENTER

①, installation

#这个类实际安装pear时默认就会安装pear Install Archive_tar

Ii

/** principle: The first 512 bytes of the TAR compression package has its own fixed format, according to these 512 bytes can get the file name of the compressed package, size and other information in conjunction with Gzopen,gzread can decompress GZ format */$tar _object = new Archive_tar (" Song.tar.gz "); $tar _object->extract (' c:/tmp ', true);

3, PHP call external command to perform decompression

Must wait for the command to complete, the script will be launched, the Popen command is not asynchronous to execute error_reporting (e_all); Ini_set ("Display_errors", 1); $handle = Popen ("TAR-XZVF Song.tar.gz 2>&1 ", ' R ');/*while (!feof ($handle)) {set_time_limit (3);  $buffer = fgets ($handle);  echo "$buffer \ n";  Ob_flush ();  Flush ();} */echo "Start \ n";p close ($handle); echo "End \ n";
