PHP - Extracting Text From Different File Formats

I have a large text file that I need to search and extract text from.

I have some code that somewhat works but is not good for what I need because it only reads one line at a time.

I need to be able to echo all code between two strings and continue scanning the entire document.

I am attaching the TXT file that is being read by the script:

Here is the script:

Code: [Select]
<?
$searchthis = "Problem:";
$search="Check:";
$matches = array();

$handle = @fopen("1numbers.txt", "r")or die("can't open file");

if ($handle)
{
    while (!feof($handle))
    {
        $buffer = fgets($handle);
        if(strpos($buffer, $searchthis) !== FALSE)
            echo "<br>". $buffer."<br>";
     if(strpos($buffer, $search) !== FALSE)
            echo "<br>". $buffer."<br>";
    }
    fclose($handle);
}
?>
you can see what this script outputs by visiting this link:

http://yourautofix.com/data/data.php

but my problem is it only outputs one line of text that finds the search match.

I need it to output all lines of text between two matches for example any text between "Problem:" and "Check:" should be Echo'd

and any text between "Check:" and "Likely:" should be echo'd

there may be 1 line or 20 lines of text between the tags... I need to print all lines between the 2 determined search strings and then continue through the text file displaying all matches between the search strings in a  large file.

any thoughts on how I can get this done or point me in the right direction?

Thanks for any input on this

I have html files in which, there are lines of urls starting with http:// (simple text, not hyperlink) without a tag. What is the simplest way to extract them?
 

Hi

I'm learning php and trying to write a script to extract registration information from a large text file. Sadly my meagre knowledge of php is letting me down a bit. It's a case of knowing what you want the script to do but not having the knowlege of how to 'say it'.

So i was hoping that if I posted my code here someone could either give me a few pointers on where i am going wrong or suggest  a better way.

The text file data luckily has a recurring format as follows (for brevity i've only included one entry, which contains made up information):

As you can see the data has a convenient boundary at the 'from' field and the colon (or so it occurred to me) so I created my script as follows:

$the_string = "

One major problem is when i write the new data to a csv file the csv contains spacings that cause it to be reproduced in a column form rather than as separate fields for each comma boundary.

So can anyone suggest either

a) a better way of extracting the data from the text file (doesn't need to be 100% clean and perfect)

b) How can i stop the spaces in the csv (i thought i would have fixed this when i stripped the tags from the string at the start??).

Any help would be greatly received by a newbie phper.

It's my first shot at performing anything moderately taxing so if I've made some blaring oversites I would very much welcome your wisdom!

Thank you

I am looking at using PHP (or whatever) to compress images/video/music when it is uploaded to be stored on the server and decompressed when required on the webpage. I know I will have to make a decompress function so it knows when to decompress to its full size, but any ideas on how to do the compression.

Requirements: biggest, best and efficient compression of music/image/video files.


Thanks in advance.
