Bug description: NOTICE error reporting fails when an undeclared var is global within
function
Hi,
I've turned error_reporting() to die() the execution of my scripts as soon
as any error, warning, notice, etc is encountered.
Yet, in the example global_test() function below,
$some_undefined_variable, which is never set, is declared global, and
$another_undefined_variable is never set and isn't declared global.
isset() returns false on both variables, yet only the line "print
$another_undefined_variable;" triggers an error.
Here's the code:
-----------------------
<?
function allErrorsFatal ($errno, $errstr, $errfile, $errline) {
global $ERROR_STR;
echo "<b>Error</b> [" . $ERROR_STR[$errno] . "] $errstr<br>\n";
echo "Fatal error in line ".$errline." of file ".$errfile."<br>";
exit -1;
break;
}
$ERROR_STR = array(1 => 'ERROR', 2 => 'WARNING', 4 => 'PARSE',
8 => 'NOTICE', 16 => 'CORE_ERROR', 32 =>
'CORE_WARNING',
64 => 'COMPILE_ERROR', 128 => 'COMPILE_WARNING', 256 =>
'USER_ERROR',
512 => 'USER_WARNING', 1024 => 'USER_NOTICE');
error_reporting (E_ALL);
set_error_handler("allErrorsFatal");
function global_test() {
global $some_undefined_variable;
if (isset($some_undefined_variable)) {
print "some_undefined_variable is set - \n";
} else {
print "some_undefined_variable is not set - \n";
}
print $some_undefined_variable;
if (isset($another_undefined_variable)) {
print "another_undefined_variable is set - \n";
} else {
print "another_undefined_variable is not set - \n";
}
print $another_undefined_variable;
}
global_test();
?>
---------------------------
Outputs:
---------------------------
some_undefined_variable is not set -
another_undefined_variable is not set -
<b>Error</b> [NOTICE] Undefined variable: another_undefined_variable<br>
Fatal error in line 33 of file /[...]/global_test.php<br>
---------------------------
IMHO, the line "print $some_undefined_variable;" should trigger the
notice. Apparently, the global keyword incorrectly affects the way
$some_undefined_variable is handled by the parser later on.
