Phar::setAlias()

(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.2.1)

Set the alias for the Phar archive

说明

publicPhar::setAlias(string $alias): bool

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 alias for the Phar archive, and write it as the permanent alias for this phar archive. An alias can be used internally to a phar archive to ensure that use of thepharstream wrapper to access internal files always works regardless of the location of the phar archive on the filesystem. Another alternative is to rely upon Phar's interception of include or to use Phar::interceptFileFuncs() and use relative paths.

参数

$alias

A shorthand string that this archive can be referred to inpharstream wrapper access.

返回值

错误／异常

Throws UnexpectedValueException when write access is disabled, and PharException if the alias is already in use or any problems were encountered flushing changes to disk.

范例

}
?>
