[Resolved] [Resolved] Pulling data and parsing it

Corpheous

How would I pull data out of a blob and parse it so I can use it? Let's say the blob holds this data:

Fire Resistance:10%, Water Resistance:20%, Dark Magic Resistance: 0%, Earth Resistance:-10%

And I want to pull it out and put it in a form more like this:

$fire_resist = Fire Resistance;
$water_resist = Water Resistance;
etc...

I searched for a bit but came up empty on parsing techniques. I just can't figure out how to pull out the data and parse it up so I can use it.

You could explode on the comma, so:

Fire Resistance:10%, Water Resistance:20%, Dark Magic Resistance: 0%, Earth Resistance:-10%

$mydataarray = explode(',', 'Fire Resistance:10%, Water Resistance:20%, Dark Magic Resistance: 0%, Earth Resistance:-10%');

And $mydataarray would be split into large pieces - but still doesn't give you what you want.

What you'll need to do now is loop each array item and split it on the colon:

$data = array();
for($a = 0; $a < count($mydataarray); $a++)
{
  $temparray = explode(':', $mydataarray[$a]);
  $data[trim($temparray[0])] = trim($temparray[1]);
}  // end for($a = 0; $a < count($mydataarray); $a++)

Now $data will contain an array indexed using the terms like 'Fire Resistance' so you should be able to do:

echo $data['Fire Resistance'] and the output should be 10%.

I think this comes close to what you're looking for. If anything, the parsing should get you started and if you need the variables to be more specific, you could get crazy with if() or switch().

Thanks, that's pretty much exactly what I was looking for 🙂

So just to make sure, what I can do now is something like pull the blob out of the database and then assign it to something like

$resistances = $row['resistances'];

and then do this?:

$mydataarray = explode(',', '$resistances');

Yup - exactly! My bad for forgetting to post that line of code. That would have helped you out a lot. But you've got it!

Thanks again, thread resolved 🙂
