Phar::loadPhar — Loads any phar archive with an alias
$filename
[, string $alias
] ) : boolThis can be used to read the contents of an external Phar archive. This is most useful for assigning an alias to a phar so that subsequent references to the phar can use the shorter alias, or for loading Phar archives that only contain data and are not intended for execution/inclusion in PHP scripts.
filenamethe full or relative path to the phar archive to open
aliasThe alias that may be used to refer to the phar archive. Note that many phar archives specify an explicit alias inside the phar archive, and a PharException will be thrown if a new alias is specified in this case.
成功时返回 TRUE， 或者在失败时返回 FALSE。
PharException is thrown if an alias is passed in and the phar archive already has an explicit alias
Example #1 A Phar::loadPhar() example
Phar::loadPhar can be used anywhere to load an external Phar archive, whereas Phar::mapPhar should be used in a loader stub for a Phar.
<?php
try {
Phar::loadPhar('/path/to/phar.phar', 'my.phar');
echo file_get_contents('phar://my.phar/file.txt');
} catch (PharException $e) {
echo $e;
}
?>
