string contains a substring

[hokieghal99]

How does one tell if a string contains a certain substring?

For example:

$a = popen("/bin/ping -c1 $rhost", "r");
$read = fread($a, 1024);
pclose($a);
if($read contains "1 received")
{
print "Ping Succeded";
}
else
{
print "Ping Failed";
}

if (strpos($read, '1 received') !== false) {
// do not use != instead!!
echo 'Ping Succeded';
} else {
echo 'Ping Failed';
}

http://www.php.net/strpos

and, since you're already reading the manual, check all other string
functions :)

Pssst. Ping doesnt work on on machines, sometimes php wont let you execute
a system command,
try this:

I meant some machines, not all.

There was another post a couple of days ago, somone wanted to have the ping
to user time in his script, but was unable to run system commands (php was
locked down)

I originaly posted a ping code snippet, but it didnt work for him, so I
wrote that workaround.
