PHP4: Warning: Undefined variable

Anon

I installed PHP 4 on both Windows 98 and Windows NT, and ran the old application I had written for PHP 3 (was working fine on PHP3) and keep getting the following errors:

Warning: Undefined variable: report in ....
or:
Warning: Supplied argument is not a valid ODBC-Link resource in D:\web\project.php3 on line 55
Warning: Use of undefined constant ....

What is wrong? I must be missing something when I was installing PHP4.

Please advise!

Weihong,

Did you ever figure this out. I just moved over to Win2000 Advanced Server and IIS 5.0 and the latest PHP for Windows and MySQL Beta for Windows and all is well except the undefined variable errors.

Thanks in advance,
Mark

I meet the same problem on Win98+MySQL+PHP4+OmmniHTTpd plat.

Anon

Same problem, every thing worked fine on Linux with Apache. But on windows 2000 with IIS 5 the 'Undefined variable warning' is present in several applications. Help me

Anon

I believe it is your php.ini and the errors reporting which is probably set to all on windows and errors on linux ... check your php.ini and set:

error_reporting = E_ERROR & ~E_NOTICE

that should take away the errors ... php allows you to use a variable that has not yet been initialized/defined ...

I use IIS 5.1 under WinXP and it's set in php.ini exactly as Mark says, but those errors still appear, can anyone give an idea?

Anon

I followed Marks instructions (NT/IIS4) I stopped "default" web site and started it again, still had the problem, it wasn't until I went into "services" and stop/started "World Wide Web Publinshing Service" that Marks advice worked.

Nice One Mark ;-)

Alternatively you can use the http://www.php.net/manual/en/function.error-reporting.php if you don't have access to the .ini file. This is what I did in a shared NT environment with much success... thanks mark.

Anon

Yes, like Nick described use:

error_reporting (55);

And all your errors are gone!

PHP-Win Ver 4.1.0

I did it
error_reporting = E_ERROR & ~E_NOTICE

no more warning of course

still not working even simpliest code

I can\'t pass argument ?!?

My script worked before ! php 4.0.6

I use the $_GET array to access all my get varibles. Like this:

url.php?param=fu&param2=bar
<body>
<?
echo $GET[param];
echo $GET[param2];
?>
</body>

results in:

fubar

I think this is more secure, and keeps it easy to know where the varible's are coming from when I go back to my code later.

However when I went to windows with some code I had written in linux, this caused some problems. Anywhere I did this it gave me the Undefiened Constant / Undefined Varible message. I tryed using quotes, and for some reason this worked sometimes such as:
echo $_GET["param"];

However, othertimes, such as when I was trying to set varibles to these, and when I would test them in an if statement, it would give me the error.

Simply changing the error logging was all it took on windows to fix this "broken code".
Changed error_reporting to this:
error_reporting = E_ERROR & ~E_NOTICE

Thanks Mark. 🙂
