PharData::offsetSet

(PHP 5 >= 5.3.0, PHP 7, PHP 8, PECL phar >= 2.0.0)

PharData::offsetSetSet the contents of a file within the tar/zip to those of an external file or string

说明

public PharData::offsetSet ( string $offset , string $value ) : void

This is an implementation of the ArrayAccess interface allowing direct manipulation of the contents of a tar/zip archive using array access brackets. offsetSet is used for modifying an existing file, or adding a new file to a tar/zip archive.

参数

offset

The filename (relative path) to modify in a tar or zip archive.

value

Content of the file.

返回值

No return values.

错误/异常

Throws PharException if there are any problems flushing changes made to the tar/zip archive to disk.

范例

示例 #1 A PharData::offsetSet() example

offsetSet should not be accessed directly, but instead used via array access with the [] operator.

<?php
$p 
= new PharData('/path/to/my.tar');
try {
    
// calls offsetSet
    
$p['file.txt'] = 'Hi there';
} catch (
Exception $e) {
    echo 
'Could not modify file.txt:'$e;
}
?>

注释

注意: PharData::addFile(), PharData::addFromString() and PharData::offsetSet() save a new phar archive each time they are called. If performance is a concern, PharData::buildFromDirectory() or PharData::buildFromIterator() should be used instead.
