using data from a function return()

[tragikx]

if you have return $varname; in a function call, how do you then use that variable?

ex:

function test() {

$sql_query = 'select * from table';

return $sql_query;

}

is it possible to return a query like this? basically i want the function to simply query the database based on passed info, and have the parsing be handled by the calling page.

if you have return $varname; in a function call, how do you then use that variable?

$my_query = test( );

The function doesn't know its an query what its returning is just a string. Your function doesnt have any coding for quering the database.

for more info on functions check the php manual.

well for what its worth..

function test() {

$x = 5;

return;

}

$testvar = test();

echo $testvar;

nothing happens...so i'm assuming that all function output has to be done within the function call? and that you cant use variables/queries/etc. to be displayed in the calling page?

Your test() function returns a null value.

Try this instead:

function test() {
	$x = 5; //$x is some local variable
	return $x;
}

$testvar = test();

echo $testvar;
