Phar::copy — Copy a file internal to the phar archive to another new file within the phar

Описание

bool Phar::copy ( string $oldfile , string $newfile )

Замечание: This method requires the php.ini setting phar.readonly to be set to 0 in order to work for Phar objects. Otherwise, a PharException will be thrown.

Copy a file internal to the phar archive to another new file within the phar. This is an object-oriented alternative to using copy() with the phar stream wrapper.

newfile

Возвращаемые значения

returns TRUE on success, but it is safer to encase method call in a try/catch block and assume success if no exception is thrown.

Errors/Exceptions

throws UnexpectedValueException if the source file does not exist, the destination file already exists, write access is disabled, opening either file fails, reading the source file fails, or a PharException if writing the changes to the phar fails.

Примеры

Пример #1 A Phar::copy() example

This example shows using Phar::copy() and the equivalent stream wrapper performance of the same thing. The primary difference between the two approaches is error handling. All Phar methods throw exceptions, whereas the stream wrapper uses trigger_error().


<?php
try {
    $phar = new Phar('myphar.phar');
    $phar['a'] = 'hi';
    $phar->copy('a', 'b');
    echo $phar['b']; // outputs "hi"
} catch (Exception $e) {
    // handle error
}

// the stream wrapper equivalent of the above code.
// E_WARNINGS are triggered on error rather than exceptions.
copy('phar://myphar.phar/a', 'phar//myphar.phar/c');
echo file_get_contents('phar://myphar.phar/c'); // outputs "hi"
?>
