Phar::offsetSet()
(PHP 5 >= 5.3.0, PHP 7, PECL phar >= 1.0.0)
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 is1,BadMethodCallException is thrown, as modifying a Phar is only allowed when phar.readonly is set to0. Throws PharException if there are any problems flushing changes made to the Phar archive to disk.
范例
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; } ?>
