PharData::setSignatureAlgorithm — Set the signature algorithm for a phar and apply it

说明

public PharData::setSignatureAlgorithm ( int $algo , string|null $privateKey = null ) : void

Note:
此方法需要将 php.ini 中的 phar.readonly 设为 0 以适合 Phar 对象. 否则, 将抛出PharException.

Set the signature algorithm for a phar and apply it. The signature algorithm must be one of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL.

参数

algo: One of Phar::MD5, Phar::SHA1, Phar::SHA256, Phar::SHA512, or Phar::OPENSSL

返回值

没有返回值。

错误／异常

Throws UnexpectedValueException for many errors, BadMethodCallException if called for a zip- or a tar-based phar archive, and a PharException if any problems occur flushing changes to disk.

更新日志

版本	说明
8.0.0	`privateKey` is now nullable.

As a note, the docs don't show the (optional) second parameter nor mention the existence of the Phar::OPENSSL class constant also available for use with this method.



To sign a phar with OpenSSL, for example...



<?php



$phar = new Phar('somephar.phar');

// ... add your files and such

$phar->setSignatureAlgorithm(Phar::OPENSSL, file_get_contents('private_key_here.pem'));

// ... do whatever else you want afterwards here ...

?>



Hope this proves useful to someone.
