Example #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 "phar://myphar.phar/b"
} catch (Exception $e) {
// Handle error
}
// The stream wrapper equivalent of the above code.
// E_WARNING 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"
?>
