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

Return Values
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.
Examples
Example #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"
?>
