Custom Functions?

OBCENEIKON

I am just getting started in learning custom functions and am having a bit of a problem. I cannot figure out why

function hello($text, $text2) {

echo "Testing<br>";
echo "$text<br>";
echo "$text2";

}

hello(asdf, two);

will work, but

function verify($text) {

echo "$text<br>";

}

if ($result->numRows() == "0") { // If incorrect, retry.

verify(Login Failed);
//echo "argh!";

}

wont.
Removing the comment from echo "argh!"; and adding it to verify(Login Failed); will display argh!

Strings

You need to surround the string in double quotes when passing it to the function like this:

verify("Login Failed");

hmm, thanks...odd thing is though, the other function didnt have any quotes and had two variables and it worked. Thats the part that was confusing me. but it works, so im not gonna argue. thanks again

It's because of the space between Login and Failed. Sending one word only does not require the spaces, but it's good practice.

asdf and two would be considered by PHP as undefined constants 🙂

<?php
function foo ($a, $b){
	echo $a." ".$b."<br>";
}
foo(a, b);
define("a", "");
foo(a, b);
?>
