Join them; it only takes a minute: Sign up How do I fix Undefined variable error in PHP? up vote 1 down vote favorite Today, I have started to learn PHP. And, I have created my first PHP file how to solve undefined index error in php to test different variables. You can see my file as follow. Test variables inside the function:
"; echo "Variable x is: $x"; echo "
"; echo "Variable y is: $y"; } myTest(); echo "
Test variables outside the function:
"; echo "Variable x is: $x"; echo "
"; echo "Variable y is: $y"; ?> I have found following error when I have run this file in browser. Notice: Undefined variable: undefined variable php solution x in /opt/lampp/htdocs/anand/php/index.php on line 19 Notice: Undefined variable: y in /opt/lampp/htdocs/anand/php/index.php on line 29 Can anybody help me to fix issue regarding it? php error-handling compiler-errors syntax-error runtime-error share|improve this question edited Dec 5 '13 at 6:10 zzlalani 8,967123155 asked Dec 5 '13 at 4:59 Anand Mistry 6112 You can make Global variable for this error . php.net/manual/en/reserved.variables.globals.php –Zeeshan Dec 5 '13 at 5:05 add a comment| 7 Answers 7 active oldest votes up vote 2 down vote The first error ($x is undefined) is because globals are not imported into functions by default (as opposed to "super globals", which are). You need to tell your function you're referencing the global variable $x: function myTest() { global $x; // $x refers to the global variable $y=10; // local scope echo "
Test variables inside the function:
"; echo "Variable x is: $x"; echo "
"; echo "Variable y is: $y"; } Otherwise, PHP cannot tell whether you are shadowing the global variable with a local variable of the same name. The second error ($y is undefined), is because local scope is just that, local. The whole point of it is that $y doesn't "leak" out of the function. Of course you cannot access $y later in your code, outside the function in which it is defined. If you could, it would be no different than a global. share|improve this answer answered Dec 5

If I use variables without initializing, it gives me an error. The source code did not change. Only the LAMP environment did. How would you solve this problem?

You should define all your variables, those warnings are there for a reason, to make you code better. Undefined variables can easily lead to typo errors in variable names. You can change the *error_reporting* level, above E_NOTICE to get rid of that, but it is highly unadvisable. share|improve this answer answered Feb 21 '11 at 1:25 Orbling 15.8k33856 add a comment| up vote 3 down vote You can set notices to not show. error_reporting(E_ALL & ~E_NOTICE) You should be developing with error_reporting(E_ALL | E_STRICT) share|improve this answer answered Feb 21 '11 at 1:24 Spechal 1,18741229 add a comment| up vote 1 down vote you can change

Published on Aug 2, 2015How to fix Notice: error in Undefined variable in PHPSo you have been writing the PHP code and you are getting this very annoying notice something about undefined variable?Then you have come to right place because we will make your notice disappeared in no time.Relying on the default value of an uninitialized variable is problematic in the case of including one file into another which uses the same variable name. It is also a major securityrisk error in php with register_globals turned on. E_NOTICE level erroris issued in case of working with uninitialized variables, however not in the case of appending elements to the uninitialized array.Ways to deal with the issue:1)Define the variables at the beginning of the function so if there are no records, the variables exist and you won't get the error. OR 2)Use empty string.So both method will just work fine, its totally upto you which method to use.Thanks for watching please subscribe to my channel if i have helped you :) Category Education License Standard YouTube License Show more Show less Loading...
