Crazy array !!!

[Anon]

I got multiple arrays (array1[],array2[] ...)included in a loop (for ...)

When using these arrays in each loop, some of them merge old values with new ones !!!

for ($cpt=0;$cpt<sizeof($array1);$cpt++)
{
$array1[$cpt] = "Hi number #$cpt";
$array2[$cpt] = "Good luck number $cpt";
print $array1[0] ."\n".$array1[1];
}

I can see :
Hi number 1
Good luck number 1
Hi number 1Hi number 2
Good luck number 2

Ideas ??? I need to empty each array for each loop ?

I use php3 and not php4 :-)

Thanks

Your using $array1[] in the forloop AND asssigning it new values, not a wise choice, this makes it very confusing.

This is how I do it, should work...

$count = $array1;

foreach($count as $pos => $val)
{
$array1[$pos] = "Hi number #$val";
$array2[$pos] = "Good luck number $val";
echo "$array1[$pos] \n $array2[$pos] \n";
}

You can find more about "foreach" here

www.php.net/manual/control-structures.foreach.php

foreach is another possibly better then for(;😉 in some cases.

if $array1[] looked like this.

$array1[0] = '';
$array1[1] = '';
$array1[2] = '';
$array1[3] = '';

for ($c = 0; $c < count($array1); $c++)

would work. but if array1[] looked like.

$array1[0] = '';
$array1[2] = '';
$array1[3] = '';

then

for(;😉 wouldn't work so great.

Improved code:

// $count = $array1; ## Not necessary

foreach($count as $pos => $val)
{
$newArray["Hi number #$val"] = "Good luck number $val";
}

foreach ($newArray as $intro => $goodluck)
echo "$intro \n $goodluck \n";

The second loop isn't necessary and could be added to the first, but it makes the code easier to read. I won't try to figure out why you are asigning these values to arrays just before echoing them though.
