split a sentesnce... HELP!!

[Anon]

Can anyone help me to split the sentence below for the first interger found:

"2. The Perfect Storm -- Sebastian Junger, 95"

i want the result like:

-2.
-The Perfect Storm -- Sebastian Junger, 95

How, i feel sick to split to 2 sentences.

Use regular expressions:

$regex = "([0-9]+.) (.)";
ereg($regex, $str, &$reg);

// this will echo: "2."
echo $reg[1];

// this will echo: "The Perfect Storm -- Sebastian Junger, 95"
echo $reg[2];

Modify regex as needed.

Off topic!

Jesus, why doo you use a & in the ereg ??
Whay is the difference between:
ereg($regex, $str, &$reg);
and...
ereg($regex, $str, $reg);

Passing by reference instead of by value. In this case just to be clear, because it is a builtin function and will use the var by reference anyway. In user defined functions you will need to do that explicitely.
