I have to admit I'm not following you. My suggestion that you use explode()
was based on the premise that you have a bunch of lines:
...
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
...
that are currently stored in a string. After explode() you can use foreach()
to loop through the array and check each line individually. Then based on
whether the line passes the check you could either:
a) unset that array element (doesn't pass check so get rid of it)
or
b) copy that element to a new array (passes check so store it in a 'good'
array)
Either way you'll end up with an array containing only 'good' lines.
