Extracting ZIP file directories in PHP

Here is the code.

<?php $toDir= getcwd();
$fromFile = "joomlacomponent.zip";
if (!file_exists($toDir))
mkdir($toDir, 0777);
if (class_exists('ZipArchive', false))
{
$zip = new ZipArchive();
if ($zip->open($fromFile) === true AND $zip->extractTo($toDir) AND $zip->close())
return true;
return false;
}
die();
?>

Deleting all files from a folder using php

Here is the code to this.

<?php

function deleteDirectory($dirPath) {

if (is_dir($dirPath)) {

$objects = scandir($dirPath);

foreach ($objects as $object) {

if ($object != "." && $object !="..") {

if (filetype($dirPath . DIRECTORY_SEPARATOR . $object) == "dir") {

deleteDirectory($dirPath . DIRECTORY_SEPARATOR . $object);

} else {

unlink($dirPath . DIRECTORY_SEPARATOR . $object);

}

reset($objects);

rmdir($dirPath);

}

echo deleteDirectory("old");

Creating a zip file with PHP

I recently had a requirement to create a zip file from a number of files created within my application.

Code Is bellow.

<?php
//include "class.recursivezip.php";
class recursiveZip
{
/**
* Recursively reads a directory and compress files
*
* @param file $src source directory
* @param file $zip recursively adds file
* @param file $path the file path
*/
private function recursive_zip($src,&$zip,$path) {
// open file/directory
$dir = opendir($src);
// loop through the directory
while(false !== ( $file = readdir($dir)) ) {
// skip parent (..) and root (.) directory
if (( $file != '.' ) && ( $file != '..' )) {
// if directory found again, call recursive_zip() function again
if ( is_dir($src . '/' . $file) ) {
$this->recursive_zip($src . '/' . $file,$zip,$path);
}
else {
// add files to zip
$zip->addFile($src . '/' . $file,substr($src . '/' . $file,$path));
}
}
}
closedir($dir);
}

/**
* Perform compression
*
* @param file $source source file/direcctory for compress
* @param file $dst destination directory where zip file will be created
* @return zip file / folder
*/
public function compress($src,$dst=''){

// check zip extension loaded or not
// and
// check soure file/directory exists or not
if (!extension_loaded('zip') || !file_exists($src)) {
return false;
}

// remove last slash (/) from source directory / destination directory
if(substr($src,-1)==='/'){
$src=substr($src,0,-1);
}
if(substr($dst,-1)==='/'){
$dst=substr($dst,0,-1);
}
$path=strlen(dirname($src).'/');
//$filename=substr($src,strrpos($src,'/')+1).'.zip';
$filename=substr($src,strrpos($src,'/')).'.zip';
$dst=empty($dst)? $filename : $dst.'/'.$filename;
@unlink($dst);

// create zip
$zip = new ZipArchive;
$res = $zip->open($dst, ZipArchive::CREATE);
if($res !== TRUE){
echo 'Error: Unable to create zip file';
exit;
}
if(is_file($src)){
$zip->addFile($src,substr($src,$path));
}
else{
if(!is_dir($src)){
$zip->close();
@unlink($dst);
echo 'Error: File not found';
exit;
}
$this->recursive_zip($src,$zip,$path);
}
$zip->close();
return $dst;
}
} // end class file

//------- for mac ------------------
// Always use absolute path
$src=$_SERVER['DOCUMENT_ROOT']."/";
$dst=$_SERVER['DOCUMENT_ROOT'];
$z= new recursiveZip();
echo $z->compress($src,$dst);

?>
