Fira Posted September 24, 2006 Share Posted September 24, 2006 I've been learning php for a month, and have made decent progress, but seem to have stumbled upon this:I've an include file, named inc.php. Within it stores many variables, one of which is called $var.I've another file, named function.php. It includes inc.php. Within function.php is a function named fun(). Would Fun() be able to recognize $var without any direct declarations within the function itself? And what if Fun() was called from another file that includes function.php?Help is appreciated.

alpine Posted September 24, 2006 Share Posted September 24, 2006 If you set $var as GLOBAL you can use it within the function fun() Quote Link to comment Share on other sites More sharing options...
Fira Posted September 24, 2006 Author Share Posted September 24, 2006 And global is only needed for usage of variables within functions?edit: Now I'm recieving the error[quote]Parse error: parse error, unexpected '=', expecting ',' or ';' in c:\WEB_ROOT\includes\include.php on line 13[/quote]Here's line 13 of include.php:[quote]global $epts = (mysql_result($result,0,'ep'));[/quote] Quote Link to comment Share on other sites More sharing options...
.josh Posted September 24, 2006 Share Posted September 24, 2006 try global $epts;$epts = mysql_result($result,0,'ep');also, unless you passed $result as an argument ot the function, you're going to have to declare it as a global too.

Barand Posted September 24, 2006 Share Posted September 24, 2006 Better than using globals - pass variables to the function as arguments and use return value.So define the function as [code]fun ($result) { $res = mysql_result($result,0,'ep'); return $res;}[/code]and call with$epts = fun($result); Quote Link to comment Share on other sites More sharing options...
