explode?

[viveleroi0]

I have something that shows up as $180 - ON HOLD
That is made into a variable from a database field. How can I remove the "ON HOLD" part and have the variable remain as $180?
I guess I would use explode?

[gid]

first of all, there's about a million different ways to do this, here's one:

$t = '$180 - ON HOLD';
$t = trim($t);

echo substr($t, 0, strpos($t, ' '));

whats another way?

[gid]

You're not going to make me go through all 1 million, are you?

$t = '$180 - ON HOLD';
preg_match('/(\$[0-9]+)/', $t, $r);
echo $r[1];

[gid]

And another:

$t = '$180 - ON HOLD';
$t = str_replace(' - ON HOLD', '', $t);
echo $t;

[gid]

And another, although this way is kinda wasteful. Doing some time trials might be kinda intersting.

$t = '$180 - ON HOLD';
list($t) = explode(' ', $t);
echo $t;
