error logging

[pradeepjain]

I have set a error_log value in php.ini and its reporting errors to that file correctly .In my site case there will be various events taking place so each will be maintained by others .So i wanted to write tht events errors to separate log files of tht events instead of writing everything to a single log file
so i tried this script but not working

<?php
ini_set('error_reporting', E_ALL);
//error_reporting(E_ALL);
ini_set('log_errors',TRUE);
ini_set('html_errors',FALSE);
ini_set('error_log', dirname(__FILE__) . DIRECTORY_SEPARATOR . 'errors.txt');
//error_log('sadfsadasd','1',dirname(__FILE__) . DIRECTORY_SEPARATOR . 'errors.txt');
ini_set('display_errors',FALSE);
error_reporting(E_ALL);

$test="ttt
echo $test;
echo "<br/>";
echo dirname(__FILE__). DIRECTORY_SEPARATOR . 'Errors.log';
?>

as u can see i have made a error in the script so tht it generates error but its not writing to new file but still writing errors to old log file in php.ini. Any way to solve this

Have you tried changing 'error_log' in your php.ini file? Surely that will change the error log file?

That will work .but there we can specify only one name ..thats the problem....

Hi.

I'm not really sure it is possible to manipulate the log the way you are trying if your intention is to catch syntax errors. Those would most likely have to be logged to the file you specify in the error_log directive.
I mean, you can't really rely on the broken syntax to set your ini values correctly, can you?

But, you can use the error_log function to catch logical errors and log them to different files.

Like say, if you had a database abstraction class and a function that handles member logins, you could do something like:
[code=php]
class MyDatabase
{
// Not botherhing with the details... just skipping ahead to the good stuff :)
public function Execute($sql) {
$result = mysql_query($sq l);
if(!$result) {
error_log(time( ) ." - Query failed: ". mysql_error(),
3, "/path/to/db/error.log");
}
else {
// Do something useful.
}
}
}

function MemberLogin($us r, $pwd)
{
$pwd = sha1($pwd);
$sql =<<<SQL
SELECT ID FROM MemberTable
WHERE User = '$usr' AND Pass = '$pwd'
SQL;

$dbLink = MyDatabase::Get Link();
$result = $dbLink->Execute($sql );

if($result->RowCount == 0) {
error_log(time( ) ." - Failed login for '$usr' ",
3, "/path/to/login/failiure.log");
return false;
}
else if($result->RowCount > 1) {
error_log(time( ) ." - Multiple users matched for user '$usr'",
3, "/path/to/impossible/error.log");
return false;
}
else {
return true;
}
}
[/code]
Get my meaning?

yup custom error logging and mailing i have tried..i wanted the way i wanted ..if i cld achieve it it would be good bcos each event there will be different coders so if i can generate a separate log for each of them they cld fix it else me monitoring each of them in a single file :(
