Phar::setAliasSet the alias for the Phar archive


public Phar::setAlias(string $alias): bool


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.



A shorthand string that this archive can be referred to in phar stream wrapper access.



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.


示例 #1 A Phar::setAlias() example

try {
$phar = new Phar('myphar.phar');
} catch (
Exception $e) {
// handle error
