Extract class

Nadat D@rk vroeg om hoe je een file moet extracten in linux dacht ik dat het wel leuk was om een class te maken die dat voor je kan doen met een paar extra opties. Ook kan deze class encrypted zip files extracten.

Download alle bestanden als ZIP

extract-class

<?php

// $exdir is the directory you want the content of the compressed file to be extracted
// use for the value of exdir unix style
// if overwrite is 1 old files with same names will be replaced, if 0 old files will be spared :P

class extract
{

// used to extract zip files
// if password is filled in the zip file will be encrypted
function extract_zip($file,$overwrite=0,$exdir="",$password=""){
	
	//building the command	
	$para['password']  = (!empty($password)) ? "-P ".$password." " : "";
	$para['overwrite'] = ($overwrite == 1) ? " -o " : " -n ";
	$para['exdir']     = (!empty($exdir)) ? "-d ".$exdir." " : "";
	exec("unzip".$para['overwrite'].$para['password']." ".$file." ".$para['exdir']);
	
}


// used to extract gz files 
function extract_gz($file,$overwrite=0,$exdir=""){
	
	//building the command
	$para['overwrite'] = ($overwrite == 1) ? "" : " -k";
	$para['exdir']     = (!empty($exdir)) ? "-C ".$exdir." " : "";
	echo exec("tar -zxf ".$file." ".$para['exdir'].$para['overwrite']);
	
}


// used to extract bz2 files 
function extract_bz2($file,$overwrite=0,$exdir=""){
	
	//building the command
	$para['overwrite'] = ($overwrite == 1) ? "" : " -k";
	$para['exdir']     = (!empty($exdir)) ? "-C ".$exdir." " : "";
	exec("tar -jxf ".$file." ".$para['exdir'].$para['overwrite']);	
	
}

// end of class
// in the future i will build a check that will verify the extracted files.
}

// example
$test = new extract();
$test->extract_gz("test.tar.gz",1"./output");

// another example
extract::extract_gz("test.tar.gz",1"./output");
?>
