Phar::setAlias
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.2.1)
Phar::setAlias — Set the alias for the Phar archive
说明
public Phar::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 the phar stream 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 in
pharstream 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
Example #1 A Phar::setAlias() example
<?phptry { $phar = new Phar('myphar.phar'); $phar->setAlias('myp.phar');} catch (Exception $e) { // handle error}?>
