Need Help Please - Searching and Extracting from Text File

[Looktrne]

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:

 

<?
$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:

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

After a search hit you need to set a state variable that you then test for to see if further lines should be output for each loop.  This variable should be cleared when you reach the end of a group of lines (the next Check or Likely?).

 

While the state variable is set you echo all lines.

 

You might run into the problem of reading too much, but the above is principally what you need to do.

Red do you have an example code I can see so I know what I am trying to do?

 

thanks

The principle:

 

$echo = false;

while (!feof($handle))

{

    $buffer = fgets($handle);

 

    if (found start pattern)

        $echo = true;

 

    if (found end pattern or a new start pattern?)

        $echo = false;

 

    if ($echo)

        echo $buffer;

}

 

You know better than me what determines the end of the sequence.

 

Cheers,

1. do you have a larger chunk of the text file with which we can 'play'?

2. how is the text file created/derived?

Thanks Red this looks like a simple concept I will play around with it tomorrow and see how it goes
