Exiting a function early

alex_the_kidd

I have this:

<?php

...

function x() {

if (condition) {
do something;
***;
}

statements;
}
...

?>
Where the stars are I want it to "fall-out" of the function. That is I want the function to end and not execute statements. Is this possible? E.g. exit; or something?

I realise I can simply do this:

<?php

...

function x() {

if (condition) {
do something;
***;
} else {

 statements;

}
}
...

Which will have the same effect. But can it be forced to exit the function?

Hope that's clear.

Thanks,

Alex.

if u want it to exit the function type

return true;
or
return false;

Alex, you want to use a return statement.

Exit will end execution of your script (program). Return will end the function, returning control to the calling code.

if ($condition) {
  statement;
  return;
}
continue...

if i understood well, you should try return;

e.g.

return FALSE;
return TRUE;
return(0);

$errmsg = "sorry, the database says she doesn't want to ";
$errmsg .= "update any tables any more today";
return $errmsg;

yup I guess I was the 2nd fastest typist 😃 -- the return statement doesn't require an expression -- or more exactly, you can return a null expression by just saying
return;

but if you want some meaningful value back then follow Kevin or axo's advice and return something that will give you information about the results of the function's operation

p.s. I was just thrilled to finally see a post I knew the answer for!

Ok that works.
