If Else Statements

[x-rusty]

When I want to check if $var has SOMETHINg, I use

if ($item_absorb_hp != '')

and if equals nothing

i use

if ($item_absorb_hp == '')

I saw someone using

if ($item_absorb_hp)

and

if (!$item_absorb_hp)

are those thesame stuff?

Using the latter format will cast the statement to boolean and check its value--if it has a value, it will most likely return TRUE, and the if will continue.

However, neither of those are the correct method of going about this. What you want is:

if (!empty($item_absorb_hp)) {
}

Thanks! How bout to check if a variable contians something?

This one:

if ($item_absorb_hp) 

is right?
