Explode() Question

When I have an exploded string. How do I break this Array into lines so that may be read individually?

php Code:

Original - php Code
$last_part = "INITIAL 24/2100Z 30.5N 49.5W 50 KTS 12HR VT 25/0600Z 31.0N 49.5W 50 KTS 24HR VT 25/1800Z 32.0N 50.0W 50 KTS 36HR VT 26/0600Z 33.0N 50.9W 50 KTS 48HR VT 26/1800Z 33.8N 52.0W 50 KTS 72HR VT 27/1800Z 34.5N 54.0W 50 KTS";

 
$last_part = "INITIAL     24/2100Z 30.5N  49.5W    50 KTS
12HR VT     25/0600Z 31.0N  49.5W    50 KTS
24HR VT     25/1800Z 32.0N  50.0W    50 KTS
36HR VT     26/0600Z 33.0N  50.9W    50 KTS
48HR VT     26/1800Z 33.8N  52.0W    50 KTS
72HR VT     27/1800Z 34.5N  54.0W    50 KTS";

RE: Explode() Question

Well, working with what you have posted, it looks like you have a newline character after each line that you would like as a seperate line. If that is always the case, you can use this:

$lines = explode("rn",$last_part);

that will place each line into a seperate array element and you can then address them as such:

php Code:

Original - php Code
echo $lines[0]; echo $lines[1]; or foreach($lines as $value) { echo "$value<BR>n"; }

 
echo $lines[0];
echo $lines[1];
 
or
 
foreach($lines as $value) {
   echo "$value<BR>n";
}

RE: Explode() Question

Does this break the lines up into a string or to another set of Arrays?
Well, at least the $lines are an Array...
Can I then explode() the $lines in seperate Arrays?

RE: Explode() Question

That breaks $last_part down into an array called $lines which has each line in a seperate element. The end result would be as if you had done this:

php Code:

Original - php Code
$lines[0] = "INITIAL 24/2100Z 30.5N 49.5W 50 KTS"; $lines[1] = "12HR VT 25/0600Z 31.0N 49.5W 50 KTS"; $lines[2] = "24HR VT 25/1800Z 32.0N 50.0W 50 KTS"; $lines[3] = "36HR VT 26/0600Z 33.0N 50.9W 50 KTS"; $lines[4] = "48HR VT 26/1800Z 33.8N 52.0W 50 KTS"; $lines[5] = "72HR VT 27/1800Z 34.5N 54.0W 50 KTS";

 
$lines[0] = "INITIAL     24/2100Z 30.5N  49.5W    50 KTS";
$lines[1] = "12HR VT     25/0600Z 31.0N  49.5W    50 KTS";
$lines[2] = "24HR VT     25/1800Z 32.0N  50.0W    50 KTS";
$lines[3] = "36HR VT     26/0600Z 33.0N  50.9W    50 KTS";
$lines[4] = "48HR VT     26/1800Z 33.8N  52.0W    50 KTS";
$lines[5] = "72HR VT     27/1800Z 34.5N  54.0W    50 KTS";

RE: Explode() Question

Now that I have the $lines Array.
Can I break up the Array again?

php Code:

Original - php Code

 
$lines[0] = "INITIAL     24/2100Z 30.5N  49.5W    50 KTS";
$lines[1] = "12HR VT     25/0600Z 31.0N  49.5W    50 KTS";
$lines[2] = "24HR VT     25/1800Z 32.0N  50.0W    50 KTS";
$lines[3] = "36HR VT     26/0600Z 33.0N  50.9W    50 KTS";
$lines[4] = "48HR VT     26/1800Z 33.8N  52.0W    50 KTS";
$lines[5] = "72HR VT     27/1800Z 34.5N  54.0W    50 KTS";
 
//Convert to
$parts[0] = "INITIAL";
$parts[1] = "24/2100Z";
$parts[2] = "30.5N";
$parts[3] = "49.5W";
$parts[4] = "50 KTS";
//...etc....

RE: Explode() Question

Well, it appears that it is lined up by character count all the way. If this is the case for all your data, you can use substr()'s to get the data you want. I would have suggested just exploding it further but the amount of spaces in there makes that difficult. Actually what you could do is replace all sets of 5 spaces to 2 spaces. replace all sets of 4 spaces to 2 spaces, then replace all occurences of Z with Z plus a space. then explode with 2 spaces as your separator. If you want an example of that, let me know....

RE: Explode() Question

Hmm... weird... I was using a FOR Statment but for some reason the first two Arrays were being exploded.
Eventhough, $i did return as Number(6). It only seemed to only count to Number(1).

Thanks again, Matt. Now to apply this to "EVERYTHING!!!" hahahaha Ok I'm getting to much power from this...
