How check whether the string is empty?

Zer0_CooL · **Author**

Hello guys!
How check whether the string is empty?

PHP Code:


			
new StringText[512]

...........
...........
...........

if (StringText[0]=='^n')
return true // string is empty
else return false // string is not empty

This is correct?

Check it against EOS:

Code:

if ( szText[0] == EOS )

Note that EOS is equal to '^0' and 0 in pawn.

if (!StringText[0])

Replace ''^n" by EOS.

You don't have to explicit it if you want.

if( StringText[0] ) // not empty
if( !StringText[0] ) // empty

in my opinion, i think he should use this condition :

if (equal(szString, ""))
return 1 // The string is empty

No he shouldn't, it's an unnecessary native call.

A null-terminated string ends where the first null character ('^n', 0, or EOS) is located. If the very first character in a string is EOS, then guess what, it's empty. Use what Emp posted, no sense in wasting a native call on something like this..
