Search text file

[muppet77]

I would like to search a text file for a date and then stop searching when the date changes.

 

Eg search for 19-10

 

18-10 monkey

19-10 bananas

19-10 nuts

20-10 leaves

 

Would return

19-10 bananas

19-10 nuts

 

Could anyone please help me make some sort of loop(?) script?

Thanks

Assuming we have a file called "date.txt" in the root directory of your filesystem.

 

<?php
 $txt = file_get_contents("http://yourdomain.com/date.txt");
 $lines = explode("\n",$txt);
 $retVal = "";
 foreach($lines as $line) {
  if(preg_match("@(\d{2}\-\d{2}(.*?)@",$line)&&(substr($retVal,0,4)!=substr($line,0,4)) $retVal .= substr($line,0) . "\n";
  else continue;
 }
 echo printf("<pre>%1</pre>",$retVal);
?> 

It's not been tested, though it should work.

 

Edit: added a minor thing.

Thanks. Where do I put the date please?

With a second look it is in the format 19-02-2009

Ah.

 

Adjust this line, then.

 

if(preg_match("@([0-3]{1}[0-9]{1}\-[0-1]{1}[0-9]{1}\-[1-2]{1}[0-9]{3})@",$line)&&(strlen($retVal)<9)&&(substr($retVal,0,9)!=substr($line,0,9))) $retVal .= $line . "\n";

I'm not particularly sure about this, but this should theoretically work.

 

Also, remove the echo before the printf function.

Thanks. This seems to keep searching the entire file which is huge.

Is there another way? The days are in order so once the day changes there will be no others later in the file. Thank you.
