#47307 [NEW]: Very wrong info in documentation
From: saskia at sa5kia dot nl
Operating system: NetBSD
PHP version: Irrelevant
PHP Bug Type: Documentation problem
Bug description: Very wrong info in documentation
Description:
------------
The information on the file_exists() function on
http://nl2.php.net/file_exists is very wrong. I spend
an hour to find out
what the problem of my script was, but your manual was the one that was
wrong. It sais the function gives a TRUE or a FALSE as an output, but this
is very incorrect. It outputs 1 or 0. This is absolutely not the same on
unix systems. TRUE or FALSE are boolean values, integers 1 or 0 are used
for this a lot, but are INTEGERS. "If" statements in php will NOT recognize
the boolean and will not function correctly when treated as one.
Please just say a function outputs 0 or 1, if it outputs 0 or 1.
Reproduce code:
---------------
$does_the_file_exist = "yes";
if ( ! file_exists( "some_not_an_existing_file" ) )
{
$does_the_file_exist = "no"
}
Expected result:
----------------
The value of $does_the_file_exist is "yes", but it should be "no".
