macOS Ping Question

[bobber205]

Whenever I ping an address through PHP (the exec command) and when it's hte second time or more since I've done the same command, I get something like this.

round-trip min/avg/max/stddev = 3.917/3.917/3.917/0.000 ms

Which is NOT what I want. Any suggestions?

or comments. There must be something I'm missing.

EDIT:
Ooh! It's not just giving me the above line, but instead exec is giving back just the last line.

3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max/stddev = 79.492/80.872/82.678/1.335 ms

Any idea on how to stop this?

That looks like what you get in Terminal...

The -c 2 limit's it to sending 2 pings

What do you want??

grep, sed, preg_replace()...hard to say since I don't understand what your actual goal is here.

 

[bobber205]

sorry.

What I actually want it is all the text from the exec command being able to be stored in a variable.

Oh. Can you post the exact code that you're trying to use? Also, try using system() instead of exec(). This works on a server that I'm using at the moment:

[atmeweb@boxwood bin]$ cat test.php
<?php
echo(system("nslookup google.com"));
?>

[atmeweb@boxwood bin]$ php-cli test.php
Server:         64.29.16.113
Address:        64.29.16.113#53

Non-authoritative answer:
Name:   google.com
Address: 72.14.207.99
Name:   google.com
Address: 64.233.167.99
Name:   google.com
Address: 64.233.187.99

You can also pass an array into exec to get lines of output stored in an array.
