$php_errormsg is indeed a local variable. The global variant is called error_get_last().

and sorry, forgot to notice, I know of set_error_handler() :-)

<?
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);

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.

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
