Simple Stupid For Loop

phence

For some reason i can't remeber how to write a for loop correctly... i looked at php.net and it was no help. Sorry to bother you with this stupid question, but it's making me mad and im spending too much time trying to figure it out..

I have a function the creates random numbers called "scores()"
now i want to call that function 7 times total, so i can get 7 numbers.

I want each number to be stored in an array called ability, then print each number out...

this is the code i have... nothing is echoed... and i have made sure that if you call the funciton it returns a number

$ability = array();

// Collect Ability scores into an array
for ($i = 0; $i >= 8; $i++)
{
	$ability = scores();	
}

// Print out Ability Scores
echo $ability[0] . "<br>";
echo $ability[1] . "<br>";
echo $ability[2] . "<br>";
echo $ability[3] . "<br>";
echo $ability[4] . "<br>";
echo $ability[5] . "<br>";
echo $ability[6] . "<br>";

What am i doing wrong!!! ahhh im so stupid, i hate for loops

Try $ability[] = scores();
don't know what scores() does, but this way will add an element to your array each time, which seems to be what you're trying to do!
edit: sorry, you told me what scores() does, I should read your post properly.

well your test condition fails.

for($i=0; $i>=8;$i++)
{
//Code
}

for $i >= 8 then run the code

Since your $i is initially 0, it fails immediately. So you for loop never run

so change it to $i<=8

lol

thanks... but still no output...

is the for loop constructed right?

patmcv

did you see both posts? You have to make the change that khoang82 suggests, and mine too!

Hi,
Almost. Try like this (full code):


for ($i = 0; $i < 6; $i++) // for x start at 0, smaller 6, increment
{ 
    $ability[$i] = scores();     

} 

// Print out Ability Scores 
echo $ability[0] . "<br>"; 
echo $ability[1] . "<br>"; 
echo $ability[2] . "<br>"; 
echo $ability[3] . "<br>"; 
echo $ability[4] . "<br>"; 
echo $ability[5] . "<br>"; 
echo $ability[6] . "<br>";

// This printout can of course be done in the for loop using: echo $ability[$i];
