Question

I have some code that extracts a bunch of data and stores the result into a variable.
When I try to run a reg expression on it, it is unable to find a match. But if I dump the variable to screen by doing an echo statement, and then copy all the data from the screen into a variable and run the regex on the new variable then it is able to find 80+ matches.

Here is the code that I am currently using:

  require 'HPVC.php';

  $hp = new HPVC('10.14.3.23', '123', '');
  echo "<br>Attempting connection";

  $hp->connect();
  echo "<br>connection succeeded";
  $data = $hp->showPSAll();
  echo "<br>closing connection...";
  $hp->close();
  echo "<br>connection closed.";

  print_r($data);
  $pattern = '/(\w+)(\s*)(\w+\/\w+|\s+)(\s*)(\|)(\s*)(\w+)(\s*)(\w+)(\s*)(\w+|\s+)(\s*)(\w+)(\s*)(\w+)(\s*)(\w+)(\s*)(\d)/i';
  echo '<br>Number of matches: '.preg_match_all($pattern, $data, $matches, PREG_PATTERN_ORDER);

Here’s what the print_r gives in part :(it’s really really long!)

         connection closed.

Could someone please assist with this issue?

Answer 1

Check your raw data. What you may be copying is slightly different than what is in $data. An example of this might be non-white space characters displaying as white space and then being copied as white space. You might have to dump $data to a file with a binary write and then look at the characters with a hex editor.

I have run into similar problems myself in the past.
