[Phplib-users] php 4.2.1

[Marko K. <Mar...@mc...>]

Hi,

I just installed php from 4.0.6 to 4.2.1, but unfortunately my project
isn't working anymore as before.

There is one example appended. A function ExtractExpLinks breaks. PHP just
stops interpreting the inc-file where this snipout was located in.

Another problem was that one of my php scripts isn't executed at all. I
don't know what's going on. Did anybody hear about caching problems or
something like that?

        function ExtractExpLinks( $s= "" )
        {
                global $ExpNames,$ExpNr;
                $ret=TRUE;
                $i=0;

                unset($ExpNames[],$ExpNr[]);

                echo '<P CLASS=dbg>';

                while($ret)
                {
                        $ret=ereg("E:{([^}]+)}{([^}]+)}",$s,$arg);
                        if ($ret)
                        {
                                $ExpNr[$i]=$arg[1];
                                $ExpNames[$i++]=$arg[2];
                                $s=str_replace($arg[0],'',$s);
                        }
                }

                return $i;
        }

Hi,

I found solutions myself. It's eventually not related to phplib, rather to
PHP itself.

>                 unset($ExpNames[],$ExpNr[]);

php 4.2.1 doesn't like (in contradiction to 4.0.4) such an unset()
command.  If I skip the [] brackets it doesn't throw an error message
anymore. But unfortunately the assignments down the snipout to these 2
arrays do not work as expected anyway... Well, have to investigate that.

Another thing was that I had somewhere in my code a typo. One ";" at a
line end was followed by a ":"! The funny thing was that php 4.2.1 didn't
give me an error message in the browser. nothing, just blank screen and
stopped processing the php script. I was totally irritated.  Only when I
reinstalled 4.0.4 I saw an error message pointing me to the type. Strange,
isn't it?

Hope I didn't bother somebody.

I had the same problem when I upgraded to 4.1.

unset was working on the page, but was not being saved if the var was
registered as a session variable.  I ended up having to assign the var
to null to get it to work.

$foo is an array
unset($foo) does not work
$foo = array() does work.

Hi Daniel,

I see.

same symptom.

> $foo = array() does work.
Oh gosh, life can be so easy.

I actually tried the same, but BEFORE this array() assignment I did a
unset($foo), where $foo was a variable defined as global inside that
function. That obviously caused that the variable disappeared in global
namespace and was just locally created with array().
So eventually I came to this solution:

	for($j=0;$j<count($ExpNames);$j++) unset($ExpNames[$j],$ExpNr[j]);

unsetting each element of the array. It works! But of course your solution
is so much nicer. ;)

Thanks for the hint!
