使用Phar来打包发布PHP程序

简单来说,Phar就是把Java界的jar概念移植到了PHP界。

Phar可以将一组PHP文件进行打包,还可以创建默认执行的stub(或者叫做?bootstrap loader),Phar可以选择是否进行压缩,可选gzip和bzip2格式。

下面举例说明如何创建和使用Phar:

假设我们的项目名称是user,包含三个文件:

user/user.class.php

1

10

<?php
?
class?user {
????private?$name="anonymous";
????private?$email="[email protected]";
?
????public?function?set_email($email) {
????????$this->email=$email;
????}
????public?function?set_name($name) {
????????$this->name=$name;
????}
????public?function?introduce() {
????????echo?"My name is $this->name and my email address is $this->email.\n";
????}
?
}

user/user.func.php

<?php
?
require_once?"user.class.php";
?
function?make_user($name,$email) {
????$u=new?user();
????$u->set_name($name);
????$u->set_email($email);
????return?$u;
}
?
function?dump_user($u) {
????$u->introduce();
}

user/test.php

<?php
require_once?"user.class.php";
?
$u=new?user();
$u->set_name("laomeng");
$u->set_email("[email protected]");
$u->introduce();

然后我们使用如下PHP程序创建Phar文件:

make_phar.php

1
2
3
4
5
<?php
$phar?=?new?Phar('user.phar', 0,?'user.phar');
$phar->buildFromDirectory(dirname(__FILE__) .?'/user');
$phar->setStub($phar->createDefaultStub('test.php',?'test.php'));
$phar->compressFiles(Phar::GZ);

执行 php make_phar.php后,可以在当前目录发现一个叫做user.phar的文件。

我们可以直接执行user.phar文件:

php user.phar,这个相当于执行user/test.php

我们还可以引用此文件:

test_phar.php

<?php
require_once?"user.phar";
require_once?"phar://user.phar/user.class.php";
$u=new user();
$u->set_name("mengguang");
$u->set_email("[email protected]");
$u->introduce();
?
require_once?"phar://user.phar/user.func.php";
?
$u=make_user("xiaomeng","[email protected]");
dump_user($u);
