Example that shows the effect of scream
This example demonstrates how scream affects the behaviour of PHP's error handler.
Пример #1 Enabling and disabling scream at runtime
<?php
// Make sure errors will be shown
ini_set('display_errors', true);
error_reporting(E_ALL);
// Disable scream - this is the default and produce an error
ini_set('scream.enabled', false);
echo "Opening http://example.com/not-existing-file\n";
@fopen('http://example.com/not-existing-file', 'r');
// Now enable scream and try again
ini_set('scream.enabled', true);
echo "Opening http://example.com/not-existing-file\n";
@fopen('http://example.com/another-not-existing-file', 'r');
?>
Результатом выполнения данного примера будет что-то подобное:
Opening http://example.com/not-existing-file Opening http://example.com/not-existing-file Warning: fopen(http://example.com/another-not-existing-file): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in example.php on line 14
Замечание: Usually one would set this in the php.ini configuration file instead of changing the code.

In the example code above, "scream.enabled" is written twice. The first instance should be "scream.disabled"
