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.

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.

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.

Örnek 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"
?>
