just starting to learn php
what is wrong with this code please ? nothing is echoed to the screen
<?php
function melon($arg1, $arg2, $arg3)
{
$result = ($arg1 + ($arg2 + $arg3));
return $result;
echo $result;
}
melon(3,3,4);
?>
ps is there any php guru on here who would volunteer to mark my (simple) php exercises ?
The reason why nothing is being echo’d is because you returned before you echo’d.
Try out this code:
<?php
function melon($arg1, $arg2, $arg3)
{
$result = ($arg1 + ($arg2 + $arg3));
echo $result;
}
melon(3,3,4);
?>
if you want to return through a function, try this code:
<?php
function melon($arg1, $arg2, $arg3)
{
$result = ($arg1 + ($arg2 + $arg3));
return $result;
}
echo melon(3, 3, 4);
?>
many thanks!
can i come back to you re: arrays ?
$result = ($arg1 + ($arg2 + $arg3));
I don’t think there parantasis are really necessary. Try removing them all and see if it still produces the same result.
same result !
