[PHP] Executing functions within ereg_replace() output

[Adam Wan]

I'm really curious as to how to output data from ereg_replace() in a
standard way.

I'm familiar with "\\1" to ouput the original string, but not sure as to how
I can use functions within the output parameter to process this value
further.

-
// here is a simple example of what i'm trying to do

$content = 'string string 12463409834234 string string';
$content = ereg_replace( "[0-9]{14}" , substr("\\1",0,5) , $content );

// this is the output i want, but the above doesnt seem to be the right way
to generate it.

string string 12363 string string


any ideas?

Make a mysql table that looks like this

tablename: mysqlcount
columns: "id" and "count"


Then add a single entry with "id" set to 1 and count set to 0, or whatever
your count was before.

Then use this code in your page.

$str = 'http://www.yourdomain.com/where/this/is/located'.$PHP_SELF;
if ( $str != $HTTP_REFERER ) {
mysql_query("UPDATE mysqlcount SET count=count+1 WHERE id=1");
}
$count_query = @mysql_query("SELECT count FROM mysqlcount WHERE id=1");
echo substr(@mysql_result($count_query,0),
0, -3).','.substr(@mysql_result($count_query,0), -3);

that should be pretty fast.
