Note: will not count occurences of search string if it is broken across 2 or more lines.
how to find the number of occurrances of a string?
Hello
I have some very long text
I need to count the number of times the phrase ‘Num photos’
appears in the global text (stored in variable $content)
Is there an efficient way to do this without resorting to parsing?
regards

function count_str_in_file($search, $file, $nocase = FALSE)
# int count_str_in_file(str search, str file[, bool nocase])
{
$handle = @fopen($file, 'r');
if($handle)
{
$i = ($nocase) ? 'i' : ''; # make case-insensitive or not
$search = preg_replace("/([^w_ ])/", "\\$1", $search);
while(!feof($handle))
{
$line = fgets($handle, 4096);
$count += preg_match("/$search/$i", $line, $matches);
}
fclose($handle);
return($count);
}
return(FALSE); # could not read file
}
