Re: [PHP] what's undefined index ?
Your message of Mon, 25 Mar 2002 11:35:57 +1100: undefined variable is when you try to use a variable before you set it, eg $foobar undefined index is when you try to reference an array index before you set it, eg $foobar[10] Hi, thank you both for the explanation. It's clear why I get the undefined, these variables *are* for various reasons undefined at the moment. However, there are NO arrays involved, f.i. KundeRemark is NOT an array it's a simple string variable created by $KundeRemark = stripslashes($val[KundeRemark]); which is a field from a SQL result which currently doesn't exist because I changed the connection to a different db where this field is named differently. So, it's undefined, fine. But why is it called undefined index where it should be undefined variable ?

RE: [PHP] what's undefined index ?
Good day, The error message refers to the KundeRemark in $val[KundeRemark], not $KundeRemark which you are trying to assign the result to. The former is (if it existed) an index, the latter is a variable.

RE: [PHP] what's undefined index ?
$KundeRemark = stripslashes($val[KundeRemark]); ^^^ \ This is fine, you're assigning TO this \ It's this bit that's undefined as you said: which is a field from a SQL result which currently doesn't exist... so, in a way, you answered your own question.

RE: [PHP] what's undefined index ?
Just a follow up - I've been doing some debugging of my own code and here are the three different errors to do with undefined varariables: Undefined variable - variable not set/declared Undefined offset- numeric index doesn't exist Undefined index - alphanumeric index doesn't exist (I may have missed out on one/some) I didn't think about offset with I sent my first reply to this thread Hope that helps someone Martin -Original Message- From: Kai Schaetzl [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 26, 2002 11:32 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] what's undefined index ?

undefined variable is when you try to use a variable before you set it, eg $foobar undefined index is when you try to reference an array index before you set it, eg $foobar[10] -Original Message- From: Kai Schaetzl [mailto:[EMAIL PROTECTED]] Sent: Monday, March 25, 2002 11:31 AM To: [EMAIL PROTECTED] Subject: [PHP] what's undefined index ?

Just to extend the explanation further. The most common cause of undefined
index is the use of unquoted array keys:
$doo = array('dah' = 'dib');
echo $doo[dah]; # incorrect, undefined index error
echo $doo['dah']; # correct, no error
