i set a variable while im in a function, but it does not keep its value
when returning to the place the function was called. is this something to
do with register_global s being off? is there anyway i can make the
variable keep its value when returning to the code where it branched from?
TIA (again)
function textsearch($the _items_descript ion){
$pos = strpos($the_ite ms_description, $search_for);
if ($the_items_des cription == "") {
$does_contain_t ext = true;
} else {
if ($pos === false) {
$does_contain_t ext = false;
} else {
$does_contain_t ext = true;
}
}
echo ("before leaving <BR>");
echo ("$does_contain _text");
echo ("<br>");
} 6 2757
its the $does_contain_t ext variable that i want to keep the val of

i fixed it, i just put $does_contain_t ext = true; at the start of the
file. thanks anyway .
i realised that what i tried wasn't working because it was always
evaluating to true, for some reason after global $does_contain_t ext; or
whatever my variable was called, it say's there's a parse error on the
first line that tried to assign the variable - $does_contain_t ext = true;

why not return the variable you need? something like:
function myfunc($var1,$v ar2) {
// lines of code
$var_of_intrest = ...
return $var_of_intrest ;
}
$what_i_want = myfunc('var1val ue','var2value' );
note that, in your code, you are not passing $search_for to your
function but you do use it. if you do not pass it, you need to put
global $search_for
inside your function.
also, your if/else construction is strange...
maybe it is a good idea to read the beginning of the manual at least?
steven.
In the function, it considers that it's a local variable unless told
otherwise, so you have to declare it as a global one: either by
putting in the function "global $does_contain_t ext;" or using the
$_GLOBALS['does_contain_t ext'] variable. Read http://www.php.net/manual/en/languag...bles.scope.php for more
informations about it. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

now in my web I have some global variables to be used in many different
subpages, in the old ASP I simply loaded a variables.asp file into memory
using the eval() function. Now I'd like to use XML but what method would I
use to load the entries from the xml file into memory and make them quickly
accessible globally in the web code? Just need to know what functions
specifically I should start reading about!

Hi all,
I did not understand why do the global vars are
initialized to NULL where as the block level variables have random
values? I know that the C standard requires this as was mentioned in a
recent thread.
I want to know why this descrimination is in place. Can't all the
variables be initialised to NULL automatically by the compiler? This
would make programming a little easier.

Hello,
I have a problem with restoring variables in the setjmp/longjmp
functions:
K&R2 for longjmp says:
"Accessible objects have the same value they had when longjmp was
called, except for automatic non volatile variables of the function
invoking setjmp, these will be undefined if modified after the setjmp

Summary
This article explores the negative ramifications of using global variables. The use of global variables is such a problem that C++ architects have called it polluting the global namespace. This article explores what happens when the global namespace becomes polluted and how to avoid this condition.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
