PHP Options/Info Functions
After being set to 1, my assert_options(ASSERT_BAIL) value stubbornly stayed there until Apache was restarted, returning it to its default of 0.
(Reproducible on my PHP Version 5.1.2, Apache/2.2.0 (Win32))

For all of you try to throw an exception in assert callback function you must set options in following form:
<?php
error_reporting(E_ALL | E_STRICT);
function assert_callcack($file, $line, $message) {
throw new Exception();
}
assert_options(ASSERT_ACTIVE, 1);
assert_options(ASSERT_WARNING, 0);
assert_options(ASSERT_BAIL, 0);
assert_options(ASSERT_QUIET_EVAL, 0);
assert_options(ASSERT_CALLBACK, 'assert_callcack');
try {
assert(false);
} catch (Exception $e) {
echo 'Yes';
}
?>

Here is an exemple how to use the assertion callback function :
<?php
assert_options( ASSERT_CALLBACK, 'assert_callback');
function assert_callback( $script, $line, $message ) {
echo 'You have a design error in your script <b>', $script,'</b> : line <b>', $line,'</b> :<br />';
echo '<b>', ereg_replace( '^.*//\*', '', $message ), '</b><br /><br />';
echo 'Open the source file and check it, because it\'s not a normal behaviour !';
exit;
}
$x = 3;
assert('is_integer( $x ) && ($x >= 0) && ($x <= 10); //* $x must be an integer value from 0 to 10' );
echo "0 <= $x <= 10";
?>
assertion is usefull for "design by contract" methodology ...
