I have a little question regarding regular expressions... I want to check
for the pattern


But, $num may not be started with another number (assume the number will be
51 , 1 will also match (the pattern 1:: is available in 51::) ... Currently,
my regular expression is:

eregi("([^0-9]$num::)", $string);

But that doesn't seem to work... The other option, the start of a line or a
: also didn't work:

eregi("([^|:]$sess_id::)", $string);

Anyone can help me with this?

Thanks in advance,

Leon Mergen
