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

Описание

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

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

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.

Пример #1 A PharData::copy() example

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

<?php
try {
    $phar = new PharData('myphar.tar');
    $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.tar/a', 'phar//myphar.tar/c');
echo file_get_contents('phar://myphar.tar/c'); // outputs "hi"
?>
