[SOLVED] Help with preg_match with file reads

[skippylou]

So I have this preg_match problem that I am hoping someone can help me with.

 

I have a file that I am reading in that contains lines like such:

 

12:00:05.609540 6 10.1.1.100.62448 -> 10.1.1.200.80 74 0 REQ

 

In a php script I have a chunk of code like:

 

$fh = fopen($procfile,'r');

while (!feof($fh)) {

  $data = fgets($fh);

  $data = trim($data);

  if (preg_match("/(\d\d:\d\d:\d\d\.\d+) (\d)+ (\d+\.\d+\.\d+\.\d+)\.(\d+) ([\<\-\>]+) (\d+\.\d+\.\d+\.\d+)\.(\d+) (\d+) (\d+) (\w+)/", $data, $matches)) {

    echo "blah";

  }

}

 

This isn't working. However the following two things do work or shed light on parts that are working:

 

1) If I just put: echo $data;  outside of the if statement, I see all the lines with their spaces trimmed, etc.  So this proves the file read is happening and it is removing whitespace, etc.  The lines look good.

2) If I change the if statement to match a static example of a sample line from the file, instead of $data, it works:

 

if (preg_match("/(\d\d:\d\d:\d\d\.\d+) (\d)+ (\d+\.\d+\.\d+\.\d+)\.(\d+) ([\<\-\>]+) (\d+\.\d+\.\d+\.\d+)\.(\d+) (\d+) (\d+) (\w+)/", "12:00:05.609540 6 10.1.1.100.62448 -> 10.1.1.200.80 74 0 REQ", $matches)) {

    echo "blah";

  }

 

With this above, I get a "blah" printed for every line in the file.  So this proves the regex is working.

 

I have also tried double-quoting ("$data"), the $data variable to see if that was it - but with no luck.

 

Can anyone shed any light on this, or have any ideas where my errors are?

 

Thanks,

 

Scott

Found my error.  I was debugging using my web interface, which html reduces number of whitespace down to 1 - when in actuality, my file had 5, 6, 8, etc. spaces between fields. 

 

Changed " " to \s* in my pattern, all good now.
