split a line into several array elements - php

Question

I just got help from some on this site and was able to let a user upload a text file, and have the in the upload process grab the file and programatically search for keywords I specify. The script then counts how many times the word is found and outputs the entire line that it was found in into an array.
So the example results returns this when using this code:
$sceneINT = $sf->countKeyWord('INT', $file);
with my class looking like so:
public static function countKeyWord($word, $file){
if(!$word)
return NULL;
$contents = file_get_contents($file);
#standardise those line endings
$contents = str_replace(array("\r","\r\n","\n\r","\n"),"\n",$contents);
$lines = explode("\n", $contents);
#find your result
$result = $line_num = array();
foreach($lines as $line_num => $l)
if(strpos($l, $word)) {
$result[] = $l;
$line_nums[] = $line_num;
}
echo "<pre>"; // I am echoing out the results for debugging purpuses
print_r($result);
echo "</pre>";
return count($result); //final result shown to the user will only be the count
}
The results from this look like this:
Array
(
[0] => 3 INT. MARTEY'S OFFICE - DAY 3
[1] => 4 INT. RONNEY'S OFFICE - DAY 4
[2] => 6 INT. - BREEZE'S APARTMENT - DAY 6
[3] => 9 INT. - WAREHOUSE/SOUNDSTAGE - DAY 9
[4] => 11 INT. EXAM ROOM - DAY 11
[5] => 12 INT. RAJA'S OFFICE - LATER 12
[6] => 14 INT. RAJA'S OFFICE - LATER 14
[7] => 15 INT. LARGE OPERATING ROOM - DAY 15
[8] => 16 INT. RAJA'S OFFICE - LATER 16
[9] => 17 INT. OLIVER'S CAR - DAY 17
[10] => 20 INT. - ROY THUNDER'S OFFICE - NIGHT 20
[11] => 22 A 2ND CLIP FROM "GOLDEN GATE GUNS"- INT. BASEMENT - DAY 22
[12] => 27 INT. HOUSE WIFE #3'S HOUSE - LATER 27
[13] => 29 INT. LIBRARY - DAY 29
[14] => 31 INT. COFFEE SHOP - NIGHT 31
[15] => 32 INT. WAITING AREA - DAY 32
[16] => 33 INT. CASTING OFFICE - DAY 33
[17] => 34 INT. CASTING OFFICE - DAY 34
[18] => 35 INT. WAITING AREA - DAY 35
[19] => 36 INT. WAITING AREA - LATER 36
[20] => 37 INT. MOTEL ROOM - DAY 37
[21] => INT. WAITING AREA - LATER
[22] => 39 INT. WAITING AREA - DAY 39
[23] => 42 INT. WAITING AREA - DAY 42
[24] => 43 INT. CASTING OFFICE - DAY 43
[25] => 44 INT. AUDITION ROOM - DAY 44
[26] => INT. AUDITION ROOM - DAY
[27] => 45 INT. WAITING AREA - DAY 45
[28] => 46 INT. CASTING OFFICE - DAY 46
[29] => 47 INT. AUDITION ROOM - DAY 47
[30] => 48 INT. CASTING OFFICE - DAY 48
[31] => 49 INT. WAITING AREA - DAY 49
[32] => 50 INT. AUDITION ROOM - DAY 50
[33] => 51 INT. CASTING OFFICE - DAY 51
[34] => 52 INT. WAITING AREA - DAY 52
[35] => 53 INT. CASTING OFFICE - DAY 53
[36] => 54 INT. BURGER JOINT - NIGHT 54
)
I need to upload the results into a database;
Taking Array[0] for example I would need to prepare that line for the database to look like this
scene: 3
int_ext: INT
scene_name: MARTEY'S OFFICE
day_night: DAY
All that will go into 1 row in the database, I don't know how to approach this. How can I take the result and split into what I need and then send it to the database so that ALL items found are stored when the user presses the SAVE button.

Answer 1

Your code has some errors.
You create array $line_num but use $line_nums to add entries
You don't use $line_nums, why do you create it?
I would use a regular expression to find all relevant information:
$contents = file_get_contents($file);
$pattern = "!INT\. (.*?) - (MORNING|NIGHT|DAY|LATER)!si";
preg_match_all($pattern, $contents, $matches);
echo '<pre>';
print_r($matches);
echo '</pre>';
.
If you really need the line number, you have to go another way:
Use preg_replace to replace all line breaks:
//OLD: $contents = str_replace(array("\r","\r\n","\n\r","\n"),"\n",$contents);
//replaces even empty rows
$contents = preg_replace("!(\r|\n|\r\n\r\n|\r\r|\n\n)!s", "\n", $contents);
You can use the the regexp of m4rc to split your data ;-)

Answer 2

Heres a really really quick regex I just did. I'm sure that you can tidy it up a bit but it gives you something to go on. I'd look up http://php.net/manual/en/function.preg-split.php
foreach($result as $line)
{
$splitLine = preg_split("/(\d{1,3})[ ]+([A-Z.]{4}) ([A-Z' ]{1,}) - ([A-Z]{3,})/", $line);
}
That should split it up into an array. I've tested it with the first line of your array. one thing to be aware of is that it wasn't clear whether there were any padding spaces before the first number on each line of the array - so you might have to play around with the regex.
