word occurence

I know fopen function is to open website (handle) but don't know how to search for number of occurences of particular word.
Would you help me ?
Thank You.

Look at preg_match and preg_match_all, it allows you to match all instances of words and patterns

http://uk.php.net/manual/en/function.preg-match.php

A few problems with preg... it will match test in testing for example easy too fix but try something like this:

PHP Code:

---

<?php
  function NumInstancesOfWord($HayStack, $Needle, $MatchCase = false)
  {
    $WordArray = array();
    # Make shure nasty chars don't affect the results.
    $HayStack  = preg_replace('#[^a-z0-9 ]#si', '', $HayStack);
    if ($MatchCase == false) # Case insensative
    {
      $WordArray = explode(' ', strtolower($HayStack));
      $Needle      = strtolower($Needle);
    }
    else
    {
      $WordArray = explode(' ', $HayStack);
    }
        
    $CountVar = 0;
    $i        = 0;
    while ($WordArray[$i])
    {
      if ($WordArray[$i] == $Needle)
      {
        ++$CountVar;
      }
      ++$i;
    }
    return ($CountVar);
  }
?>

---

Example:

PHP Code:

---

<?php
  echo NumInstancesOfWord('This is a test, testing 123, testing 1123', 'test'); # Returns 1
  echo NumInstancesOfWord('This is a test, testing 123, testing 1123', 'testing '); # Returns 2
?>

I'm not shure what you mean, the name of the site or the contents of the file?

If the second the contents can be grabbed as follows:

PHP Code:

---

<?php
  $Contents = implode('', file('www.anyname.com/home.asp'));
?>

---

Then just plug that in as a parameter :)

Not working :rolleyes:

Code:

<?php
        function NumInstancesOfWord($HayStack, $Needle, $MatchCase = false)
        {
          $WordArray = array();
                # Make shure masty chars don't affect the results.
                $HayStack  = preg_replace('#[^a-z0-9 ]#si', '', $HayStack);
          if ($MatchCase == false) # Case insensative
                {
            $WordArray = explode(' ', strtolower($HayStack));
                        $$Needle  = strtolower($Needle);
          }
                else
                {
            $WordArray = explode(' ', $HayStack);
                }
               
                $CountVar = 0;
                $i        = 0;
                while ($WordArray[$i])
                {
                  if ($WordArray[$i] == $Needle)
                        {
                          ++$CountVar;
                        }
                  ++$i;
                }
                return ($CountVar);
        }
        $TestStr = 'This is a test, test ing 123, testing 1123';
        echo ('There are ' . NumInstancesOfWord($TestStr, 'testing') . ' instances of testing.<br />');
        echo ('There are ' . NumInstancesOfWord($TestStr, 'test')    . ' instances of test.<br />');
        $Contents = implode('', file('http://vbforums.com/showthread.php?p=2338266#post2338266'));
        //echo($Contents);
        echo ('There are ' . NumInstancesOfWord($Contents, 'slice')    . ' instances of slice.<br />');
//        echo ($TestStr);
?>

This version seems too work better.

The problem was that I checked for only the character, not the instance of the needle.
