Hi,
I maid the modifications you suggested. For the error
context when i display it, it gives a lot of
information, but not easy to understand how the array
is structured. If somebody knows about a site
explaining how to access the context it would be
great.
I also modified the error reporting to E_ALL as you
suggested. Now an other question arise: For the
connection to the database if i put a wrong username
or password the error is reported automatically to the
function that i defined as the error handling
function, but for the next statement (see code below)
if i put a wrong database name the error is not
reported automatically, i have to trigger it using
triger_error. So i'm wondering if there are some rules
that can help me know if an error will be reported
automatically or not. here is my code after
modification:
<?php
function error_handler($errno, $errstr, $filename,
$lineno, $errcontext)
{
echo "handling reported error<br>";
switch($errno) {
case E_USER_ERROR: $type = "E_USER_ERROR";break;
case E_USER_WARNING: $type =
"E_USER_WARNING";break;
case E_USER_NOTICE: $type = "E_USER_NOTICE";break;
case E_ERROR: $type = "E_ERROR";break;
case E_WARNING: $type = "E_WARNING";break;
case E_PARSE: $type = "E_PARSE";break;
case E_NOTICE: $type = "E_NOTICE";break;
case E_CORE_ERROR: $type = "E_CORE_ERROR";break;
case E_CORE_WARNING: $type =
"E_CORE_WARNING";break;
case E_COMPILE_ERROR: $type =
"E_COMPILE_ERROR";break;
case E_STRICT: $type = "E_STRICT";break;
case E_COMPILE_WARNING: $type =
"E_COMPILE_WARNING";break;
case E_RECOVERABLE_ERROR: $type =
"E_RECOVERABLE_ERROR";break;
default: echo "<br>This is an error not listed";
}
$str = "";
$str .= "<br><br>ERROR TYPE: ". $type;
$str .= "<br><br>ERROR Number: ". $errno;
$str .= "<br>ERROR MESSAGE: ". $errstr;
$str.= "<br>File: ". $filename;
$str.= "<br>Line number: ". $lineno;
echo $str;
echo "Context: <br>";
print_r($errcontext);
}
echo "<h1>Testing set_error_handler</h1>";
error_reporting(E_ALL);
set_error_handler('error_handler');
mysql_connect("localhost", "admin", "admin");
mysql_select_db("wrongdb") or trigger_error("wrong
database");
