word occurence

[slice]

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

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

<?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
  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
?>

and both are returning 1.

and both are returning 1.

There are 2 instances of testing.
There are 1 instances of test.
This is a test, testing 123, testing 1123

Exact code in file attatched.

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

Then just plug that in as a parameter

This version seems too work better.

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