Phar::offsetSet
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
Phar::offsetSet — Set the contents of an internal file to those of an external file
说明
public Phar::offsetSet
( string $offset
, string $value
) : void
Note:
此方法需要 将
php.ini中的phar.readonly设为0以适合 Phar 对象. 否则, 将抛出PharException.
This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a Phar archive using array access brackets. offsetSet is used for modifying an existing file, or adding a new file to a Phar archive.
参数
offset- The filename (relative path) to modify in a Phar.
value- Content of the file.
返回值
No return values.
错误／异常
if phar.readonly is 1,
BadMethodCallException is thrown, as modifying a Phar
is only allowed when phar.readonly is set to 0. Throws
PharException if there are any problems flushing
changes made to the Phar archive to disk.
范例
Example #1 A Phar::offsetSet() example
offsetSet should not be accessed directly, but instead used
via array access with the [] operator.
<?php$p = new Phar('/path/to/my.phar', 0, 'my.phar');try { // calls offsetSet $p['file.txt'] = 'Hi there';} catch (Exception $e) { echo 'Could not modify file.txt:', $e;}?>
