generating pdf _ trouble

[jakebur01]

I am having trouble generating a .pdf . I have a html page with several form fields, I am only posting two fields to php for testing purposes. I created a .pdf named PHPCertification.pdf with

<<NAME>>

<<Name>>

<<score>>

<<mm/dd/yyyy>>

in the text.

 

Here is my php code:

<?php
  set_time_limit( 180 ); // this script can be slow

  //create short variable names
  $SSC_COMPANY = $_POST['SSC_COMPANY'];
  $SSC_DATE = $_POST['SSC_DATE'];

  function pdf_replace( $pattern, $replacement, $string )
  {
    $len = strlen( $pattern );
    $regexp = '';
    for ( $i = 0; $i<$len; $i++ )
    {
      $regexp .= $pattern[$i];
      if ($i<$len-1)
        $regexp .= "(\)\-{0,1}[0-9]*\(){0,1}";
    }
    return ereg_replace ( $regexp, $replacement, $string );
  }
  
  if(!$SSC_COMPANY||!$SSC_DATE)
  {
    echo '<h1>Error:</h1><p>This page was called incorrectly</p>';
  }
  else
  {
    //generate the headers to help a browser choose the correct application
    header( 'Content-Disposition:  filename=cert.pdf');
    header( 'Content-type: application/pdf' );

$date = date( 'F d, Y' );
  
    // open our template file
    $filename = 'PHPCertification.pdf';
    $fp = fopen ( $filename, 'r' );
    //read our template into a variable
    $output = fread( $fp, filesize( $filename ) );

    fclose ( $fp );

   // replace the place holders in the template with our data
    $output = pdf_replace( '<<NAME>>', $SSC_COMPANY, $output );
    $output = pdf_replace( '<<Name>>', $SSC_COMPANY, $output );
    $output = pdf_replace( '<<score>>', $SSC_DATE, $output );
    $output = pdf_replace( '<<mm/dd/yyyy>>', $date, $output );
   
    // send the generated document to the browser

    echo $output;
  }
?>

 

I get an acrobat message box saying that the file is damaged and could not be repaired.
