Another Simple One..

[Schwalbach]

Ok guys, I have a text file, sorted like this(for flash reasons)

&count1=0&count2=0&count3=0

So I use an explode to explode this data:

$count = explode("=", $file);

This is ok, but then when I do an echo for $count[2] (or whichever one turns out like this) I want a number, and I get 0&count2
I just want the count's in diff. array's(actually, I can get rid of the count's fully, I just need to know which numbers correspond with what. So how can I explode both, so I come out with numbers, and then use those numbers later on?

Thanks yet again, I always get stuck on easy stuff..

change $count = explode("=", $file);

to $count = explode("&", $file);

Your "&" is your delimiter, you still need the assignment operator ("=") or php won't create vars from the GET vals

[weekender]

//the string from the file
$string = "&count1=0&count2=0&count3=0";

$parts = explode("&", $string);
//now $parts[0] = "count1=0", $parts[1] = "count2=0" etc

//split the array into keys and values, and run the loop on each pair
foreach($parts as $key => $value){
$temp = explode("=", $value);
echo "Name: " . $temp[0] . " & Value: " . $temp[1] . "<BR>";
}

the above code will echo
Name: count1 & Value: 0<BR>
Name: count2 & Value: 0<BR>
Name: count3 & Value: 0<BR>

Here's another option....

$file  = '&count1=1&count2=3&count3=6';
$count = explode('=',$file);
$numbers = array();
foreach($count as $c) {
   $num = str_replace(strstr($c,"&"),"",$c);
   if(!empty($num)) {
      $numbers[] = $num;
   }
}

The actual numbers will now be in their own array.

see how you guys are??? i give the most simple answer and you go and take the next step and help him (or her) out even more...

... just kidding... that's what I love the most about this place (phpbuilder)!!

but seriously for a minute, just an extra tip that when you use the foreach() make sure that you first test that the var is an array or php will throw an ugly error. I'm adding this because the original poster stated that 'I always get stuck on easy stuff' and I remember that was an error I hated when I first started with php4....

heres the code, to use LordShryku 's example

$file = '&count1=1&count2=3&count3=6';
$count = explode('=',$file);
$numbers = array();
foreach($count as $c) {
$num = str_replace(strstr($c,"&"),"",$c);
if(!empty($num)) {
$numbers[] = $num;
}
}

would be best as

$file = '&count1=1&count2=3&count3=6';
$count = explode('=',$file);
$numbers = array();
if (is_array($count)) {
foreach($count as $c) {
$num = str_replace(strstr($c,"&"),"",$c);
if(!empty($num)) {
$numbers[] = $num;
}
}
} else {
// some code for the times when flash doesn't send vars, maybe a
die("Error, vars haven't made it from Flash...<br>");
}

Happy Holidays to All!

Using explode, you will always end up with an array. If you don't use it right, then you'll get the error before you even get to the loop. Use on something that it can't explode on, and it will still create the array. Example:

$file  = '&count1=1&count2=3&count3=6';
$count = explode('blah',$file);
print_r($count);

This will still return an array

Array ( [0] => &count1=1&count2=3&count3=6 )

Thanks again 🙂

would it not be easiest to use [man]parse_str/man? 🙂

[coditoergosum]

Damn, Moonglobe beat me to it. 😃

Yeah, just use parse_str().
