[RESOLVED] strange action of a string

[Mgccl]

ok... I'm totally SCREWED by this script... I tired everything for 8 HOURS and this is still giving me errors like CRAZY

<?php
$count = 1;
$i = 0;
while($i < $count){
   $str_expected[$i] = '$expected["'.$i.'"] = 1/(1+pow(10, (func_math_mean_array($array';
   $str_expected[$i] .= ') - $elo['.$i.'])/400));';
echo $str_expected[$i].'<br>';
echo '$expected["0"] = 1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));';

//test see if it's true
if ($str_expected[$i] == '1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));') {
	echo 'true';
}

$i++;
}
?>

I mean in what way does this SCRIPT never echos TRUE! I mean... look at the result THE RESULT IS AMAZINGLY CALLING the word SAME!
THE HELL IS WRONG WITH PHP! GOD! it was include in a big script! I used 8 hours to find out this freaken thing is screwing with me by using unexplainable way!
what the hell it WRONG...
soory for the extreme expression of my emotion...
any one can answer me plz... it's the 1st time I get screwed by PHP so much...

Well, the simple answer is that you're comparing:

$expected["0"] = 1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));

with

1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));

Which are clealy not the same.

God no... ofcause not that... that's not the problem. you can try again with out the <br>

[madwormer2]

It's not the <br> bit, it's the $expected["0"] = bit, ITS NOT IN THE SECOND STRING, BUT IS IN THE FIRST ONE.

Duh!

[Mgccl]

oh that!, let me test
man thx you are sooooooo master
sooooooooooo masterrrrrrrr
thhhhhhhx!!!!

Umm... I have an answer to this:

$str_expected[$i] = '$expected["'.$i.'"] = 1/(1+pow(10, (func_math_mean_array($array';

Okay...

$str_expected[$i] .= ') - $elo['.$i.'])/400));'; 

Okay....

if ($str_expected[$i] == '1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));')

Expand this:

if( '$expected["0"] = 1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400);' == '1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));')
    echo true;

Do you see the difference.... here it is on two lines:

$expected["0"] = 1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400);
1/(1+pow(10, (func_math_mean_array($array) - $elo[0])/400));

Notice a difference?

EDIT
CRAP!!! Much too slow in actually pointing it out 🙁

[madwormer2]

Lol, notice how he didn't even see it when they were put next to each other in my above post :p

[Mgccl]

yeah... I was very stupid not to see that
