If you get blank pages when trying to access a phar web-page, then you probably have Suhosin on your PHP (like in Debian and Ubuntu), and you need to ad this to your php.ini to allow execution of PHAR archives :
suhosin.executor.include.whitelist="phar"
Users should set the `sys_temp_dir` directive.
PHAR stores temporary files in either `sys_temp_dir` or the current working directory(CWD).
This is especially important if you're CWD is on a remote file system. Often web server clusters will share a common file system between each web server (using NFS, DFS, etc...). In such scenarios, if you don't set `sys_temp_dir` to a local directory, PHAR will be creating temporary files over the network, which will result in performance and functionality problems.
Here is an apache2 htaccess example that prevents the downloading of phar-Archives by the user:
RewriteEngine on
RewriteRule ^(.*)\.phar$ - [F]
It triggers a "403 - Forbidden" message instead of delivering the archive.
Here is a very simple class to build a phar file from a given source directory. You can use this for your own project and simple deployment.
But my main goal was to show how to use PHAR functions in a simple way.
<?php
class BuildPhar
{
private $_sourceDirectory = null;
private $_stubFile = null;
private $_outputDirectory = null;
private $_pharFileName = null;
/**
* @param $_sourceDirectory // This is the directory where your project is stored.
* @param $stubFile // Name the entry point for your phar file. This file have to be within the source
* directory.
* @param null $_outputDirectory // Directory where the phar file will be placed.
* @param string $pharFileName // Name of your final *.phar file.
*/
public function __construct($_sourceDirectory, $stubFile, $_outputDirectory = null, $pharFileName = 'myPhar.phar') {
if ((file_exists($_sourceDirectory) === false) || (is_dir($_sourceDirectory) === false)) {
throw new Exception('No valid source directory given.');
}
$this->_sourceDirectory = $_sourceDirectory;
if (file_exists($this->_sourceDirectory.'/'.$stubFile) === false) {
throw new Exception('Your given stub file doesn\'t exists.');
}
$this->_stubFile = $stubFile;
if(empty($pharFileName) === true) {
throw new Exception('Your given output name for your phar-file is empty.');
}
$this->_pharFileName = $pharFileName;
if ((empty($_outputDirectory) === true) || (file_exists($_outputDirectory) === false) || (is_dir($_outputDirectory) === false)) {
if ($_outputDirectory !== null) {
trigger_error ( 'Your output directory is invalid. We set the fallback to: "'.dirname(__FILE__).'".', E_USER_WARNING);
}
$this->_outputDirectory = dirname(__FILE__);
} else {
$this->_outputDirectory = $_outputDirectory;
}
$this->prepareBuildDirectory();
$this->buildPhar();
}
private function prepareBuildDirectory() {
if (preg_match('/.phar$/', $this->_pharFileName) == FALSE) {
$this->_pharFileName .= '.phar';
}
if (file_exists($this->_pharFileName) === true) {
unlink($this->_pharFileName);
}
}
private function buildPhar() {
$phar = new Phar($this->_outputDirectory.'/'.$this->_pharFileName);
$phar->buildFromDirectory($this->_sourceDirectory);
$phar->setDefaultStub($this->_stubFile);
}
}
//END Class
//Example Usage:
$builder = new BuildPhar(
dirname(__FILE__).'/_source',
'my_default_stub.php',
dirname(__FILE__).'/_output',
'my-phar-file.phar'
);
Here is a very simple program for creating phar files with CLI. Note that it requires phar.readonly in php.ini set to false (Off).
<?php
$filename = "default";
$dir = "./";
$regex = "/^(?!.*build\\.php)(?:.*)$/";
$main = "main.php";
$shebang = "#!/usr/bin/env php";
$chmod = true;
for ($i = 0; $i < $argc; $i++) {
switch ($argv[$i]) {
case "-o":
$i++;
if ($i >= $argc) {
echo "Missing output file name" . PHP_EOL;
exit(1);
}
$filename = $argv[$i];
break;
case "-i":
$i++;
if ($i >= $argc) {
echo "Missing input directory name" . PHP_EOL;
exit(1);
}
$dir = $argv[$i];
break;
case "-p":
$i++;
if ($i >= $argc) {
echo "Missing regular expression pattern" . PHP_EOL;
exit(1);
}
$regex = $argv[$i];
break;
case "-m":
$i++;
if ($i >= $argc) {
echo "Missing main file" . PHP_EOL;
exit(1);
}
$main = $argv[$i];
break;
case "-b":
$i++;
if ($i >= $argc) {
echo "Missing shebang of file" . PHP_EOL;
exit(1);
}
$shebang = $argv[$i];
break;
case "--no-chmod":
$chmod = false;
break;
}
}
if (file_exists($filename)) unlink($filename);
$phar = new Phar($filename);
$phar->buildFromDirectory($dir, $regex);
$phar->setStub(($shebang ? $shebang . PHP_EOL : "") . $phar->createDefaultStub($main));
if ($chmod) {
chmod($filename, fileperms($phar) | 0700);
}
when read via phar://, stream will unserialize object including phar file
Use this to create phar
<?php
// create new Phar
$phar = new Phar('lemon.phar');
$phar->startBuffering();
$phar->addFromString('test.txt', 'text');
$phar->setStub('<?php __HALT_COMPILER(); ? >');
// add object of any class as meta data
class AnyClass {}
$object = new AnyClass;
$object->data = 'Chanh';
$phar->setMetadata($object);
$phar->stopBuffering();
?>
and read it by:
<?php
class AnyClass {
function __destruct() {
echo $this->data;
}
}
// output: Chanh
file_get_contents('phar://test.phar');
?>
