Thank's a lot for this information. I tried this but
one thing is not suitable so far for me while
using explode.
E.g. if have the output of route -n:
xxx.x.x.x 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
0.0.0.0 xxx.x.x.x 0.0.0.0 UG 0 0 0 ppp0
By using this example it's quite easy to analyze all
lines due to a correct syntax:
$INET_NUM = ereg_replace("[\ ]+([a-z]+)([0-9]{1})","\\1\\2_XrR",$INET_NUM);
$sorter = explode("_XrR",$INET_NUM);
But it has one weakness. In the case the device (ppp0) is
missing somewhere in the output as the user didn't intend
to integrate this required information, and by having insight
it could be more than 10 lines with 10.000 rules of
netfilter, explode will show concerning this example of 3
lines 2 defined arrays and it won't lead to an error as
explode doesn't give a return value back which
has not been proofed to be exploded with _XrR.
As I want to proof the syntax of all lines this is
wrong and not usable.
What I would need is a function which counts, based on a
regular expression, how many times this shema occurs inside
of a string. So I can reduce the possibilty to have not an
error and I could proof against the missing device by
searching for 3 ip addresses followed by spaces and so on.
E.g. the above example of explode would show 2 set arrays
but with a regular expression which counts all ip addresses
and so on it would show 3 lines matching the construct. The
difference would lead then to an error message as the user
input was wrong.
