compser可以检查php扩展吗,composer扩展

## 一些简单的thinkphp扩展

1. 正则表达式的扩展：

PHP7以上：

```

composer req gherkins/regexpbuilderphp

```

PHP5

```

composer req gherkins/regexpbuilderphp:0.7.*

```

[使用文档](https://github.com/gherkins/regexpbuilderphp/wiki)

[实例](https://github.com/gherkins/regexpbuilderphp)

2.Blade模板引擎扩展

```

composer require terranc/think-blade

```

[GitHub文档](https://github.com/terranc/think-blade)

3.Twig模板引擎扩展

```

composer require yunwuxin/think-twig

```

[GitHub使用文档](https://github.com/yunwuxin/think-twig)

4.Swoole扩展

```

composer require topthink/think-swoole

```

[GitHub使用文档](https://github.com/top-think/think-swoole)

5.phpmailer扩展文件

```

composer require phpmailer/phpmailer

```

或者在composer.json中手动增加一个phpmailer require

```

"require": {

"php": ">=5.4.0",

"topthink/framework": "^5.0",

"topthink/think-image": "^1.0",

"topthink/think-captcha": "^1.0",

"topthink/think-mongo": "^1.0",

"topthink/think-migration": "^1.0",

"topthink/think-angular": "^1.0",

"topthink/think-sae": "^1.0",

"topthink/think-worker": "^1.0",

"topthink/think-queue": "^1.0",

"topthink/think-testing": "^1.0",

"phpmailer/phpmailer": "^5.2"

},

```

然后使用phpmailer类：

```

public function testmailer(){

$mail = new PHPMailer;

dump($mail);

}

```

打印结果:

```

object(PHPMailer)#5 (75) {

["Version"] => string(6) "5.2.16"

["Priority"] => NULL

["CharSet"] => string(10) "iso-8859-1"

["ContentType"] => string(10) "text/plain"

["Encoding"] => string(4) "8bit"

["ErrorInfo"] => string(0) ""

["From"] => string(14) "root@localhost"

["FromName"] => string(9) "Root User"

["Sender"] => string(0) ""

["ReturnPath"] => string(0) ""

["Subject"] => string(0) ""

["Body"] => string(0) ""

["AltBody"] => string(0) ""

["Ical"] => string(0) ""

["MIMEBody":protected] => string(0) ""

["MIMEHeader":protected] => string(0) ""

["mailHeader":protected] => string(0) ""

["WordWrap"] => int(0)

["Mailer"] => string(4) "mail"

["Sendmail"] => string(18) "/usr/sbin/sendmail"

["UseSendmailOptions"] => bool(true)

["PluginDir"] => string(0) ""

["ConfirmReadingTo"] => string(0) ""

["Hostname"] => string(0) ""

["MessageID"] => string(0) ""

["MessageDate"] => string(0) ""

["Host"] => string(9) "localhost"

["Port"] => int(25)

["Helo"] => string(0) ""

["SMTPSecure"] => string(0) ""

```

下一步为了分便使用可以把配置函数写到common.php公共函数文件中如

```

function SendMail($address,$title,$message)

{

$mail=new \PHPMailer;

// 设置PHPMailer使用SMTP服务器发送Email

$mail->IsSMTP();

// 设置邮件的字符编码，若不指定，则为'UTF-8'

$mail->CharSet='UTF-8';

// 添加收件人地址，可以多次使用来添加多个收件人

$mail->AddAddress($address);

// 设置邮件正文

$mail->Body=$message;

// 设置邮件头的From字段。

$mail->From=C('MAIL_ADDRESS');

// 设置发件人名字

$mail->FromName='LilyRecruit';

// 设置邮件标题

$mail->Subject=$title;

// 设置SMTP服务器。

$mail->Host=C('MAIL_SMTP');

// 设置为"需要验证"

$mail->SMTPAuth=true;

// 设置用户名和密码。

$mail->Username=C('MAIL_LOGINNAME');

$mail->Password=C('MAIL_PASSWORD');

// 发送邮件。

return($mail->Send());

}

```
