Number of Instances of a Specific Word in a Log File

[feedyourself]

I'm pretty sure this is really simple to do using the count function, but I am having a hard time finding examples on how to count the number of times a "SPECIFIC" word occurs in a file. For example, I just want to display how many times "this-word" occurs in "http://www.mysite.com/logfile.log". Any help would be appreciated.

One way:

 

$count = preg_match_all('#\bsomeword\b#', file_get_contents('logfile.log'), $matches);

You could also use substr_count() for seeing how many times this-word appears, if there is no need for a regular expression like above.

 

If the log file is big, then it might be better to move through the file a piece at a time and tally up the number of occurences of the word.

Forgot about that one.  Probably much faster also.  But you may have problems with the word being part of a larger word, etc.  So you would want to add a space before and after, but then you have problems if the word is at the beginning or end of a line, etc...  Depends on what you want.

A key point. Lets see if the OP gives any feedback.
