How to extract tar.gz format files in PHP _php tips

This article illustrates the way PHP extracts tar.gz format files. Share to everyone for your reference, specific as follows:

1, the use of PHP with compression and archive expansion (Phar)

$phar = new Phardata (' song.tar.gz ');
Path to extract whether the file overwrites
$phar->extractto (' c:/tmp ', NULL, true);

2, the first need to install Pear class management tools

Linux under

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

Wamp default does not install pear, go-pear.php for older versions, php5.3 need to download Go-pear.phar

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

①, installation

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

/**
principle: Tar compression package before 512 bytes have their own fixed format, according to these 512 bytes can get the file name of the compression package, size and other information
in conjunction with Gzopen,gzread can extract GZ format
 * * *
$tar _ Object = new Archive_tar ("song.tar.gz");
$tar _object->extract (' c:/tmp ', true);

3, PHP calls the external command to perform decompression

The script will not be launched until the command is executed, and 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 "$buffer \ n";
  Ob_flush ();
  Flush ();
} * *
echo "start \ n";
Pclose ($handle);
echo "End \ n";
