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

publicPhar::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;
}
?>
