How can I split a string at the first occurrence of "-" (minus sign) into two $vars with PHP?

How can I split a string at the first 开发者_如何学Pythonoccurrence of - (minus sign) into two $vars with PHP?

I have found how to split on every "-" but, not only on the first occurrence.

example:

this - is - line - of whatever - is - relevant
$var1 = this
$var2 = is - line - of whatever - is - relevant

Note, also stripped the first "-" .

It's very simple, using an extra paramater to explode that many people don't realize is there:

list($before, $after) = explode('-', $source, 2);

---

$array = explode('-', 'some-string', 2);

Then you could do $var1=$array[0] and $var2=$array[1].

Here is what you need: using list() with explode():

list($var1, $var2) = explode(' - ', 'this - is - line - of whatever - is - relevant', 2);

Note the spaces around the "-" (minus sign)

You can use strtok function:

$first = strtok($string, '-');
