Description:
------------
in debug mode, my script stores every error that occured in the script. when an error occurs in eval(), the error is stored correctly in $php_errormsg. however when the error occured in a function called by eval() the error isn't stored anymore.
Reproduce code:
---------------
register_tick_function("store_errors", true);
function &store_errors($do_tick = true) {
GLOBAL $php_errormsg;
static $errors = array();
if ($do_tick) {
if (isset($php_errormsg) && $php_errormsg != "") {
if ($trace = debug_backtrace()) {
$func = $trace[1]['function'];
if (isset($trace[1]['class']))
$func = $trace[1]['class'].$trace[1]['type'].$func;
}else {
$func = 'unknown';
}
$errors[] = array(
0 => $php_errormsg,
1 => $func
);
$php_errormsg = "";
}
}else {
return $errors;
}
}
/* stupid test function */
function blah() { echo $blah2; echo "error is set here: $php_errormsg<br>"; }
eval ('echo $blah1; blah();');
$ar = store_errors(false);
while(list($key,$val) = each($ar)) {
echo "{$key} => {$val[0]} in {$val[1]}<br>\n";
}
Expected result:
----------------
Notice: Undefined variable: blah1 in /home/dush/public_html/core/loader.inc.php(28) : eval()'d code on line 1
Notice: Undefined variable: blah2 in /home/dush/public_html/core/loader.inc.php on line 27
error is set here: Undefined variable: blah2
0 => Undefined variable: blah1 in unknown
1 => Undefined variable: blah2 in blah
Actual result:
--------------
Notice: Undefined variable: blah1 in /home/dush/public_html/core/loader.inc.php(28) : eval()'d code on line 1
Notice: Undefined variable: blah2 in /home/dush/public_html/core/loader.inc.php on line 27
error is set here: Undefined variable: blah2
0 => Undefined variable: blah1 in unknown

Can't find any errors here: <? eval('echo $blah;'); var_dump($php_errormsg); echo $bla; var_dump($php_errormsg); ?> outputs: --- Notice: Undefined variable: blah in /www/index.php(3) : eval()'d code on line 1 string(24) "Undefined variable: blah" Notice: Undefined variable: bla in /www/index.php on line 7 string(23) "Undefined variable: bla" --- Check your code.<? function bla3() { echo $bla3; var_dump($php_errormsg); } echo $bla2; var_dump($php_errormsg); eval('echo $bla1;'); var_dump($php_errormsg); eval('bla3();'); var_dump($php_errormsg); ?> outputs: Notice: Undefined variable: bla2 in /home/dush/public_html/test.php on line 8 string(25) "Undefined variable: bla2" Notice: Undefined variable: bla1 in /home/dush/public_html/test.php(10) : eval()'d code on line 1 string(25) "Undefined variable: bla1" Notice: Undefined variable: bla3 in /home/dush/public_html/test.php on line 5 string(25) "Undefined variable: bla3" string(25) "Undefined variable: bla1" It's certainly not a bug if it's supposed to be a different $php_errormsg for every scope, but I thought it was a global variable. If I'm not correct, please think of adding something like $global_php_errormsg, as it would be very handy for debugging purposes without having errors on possibly a lot of different positions on a page with error_reporting(E_ALL);
