Question

I have the string 1. Welcome.

I’d like to split the string into 2 strings: 1 & Welcome.

How would I use substr PHP function to achieve this?

Many thanks for any pointers

For this particular case, the most appropriate function would be explode:

$str = '1. Welcome';
$parts = explode('. ', $str);

// explode returns a numerically indexed array, so:
$number = $parts[0];
$title = $parts[1];

You can combine this with the list construct for extra convenience:

list($number, $title) = explode('. ', $str);

Finally, it’s a good idea to specify the third parameter of explode (limit to how many tokens are generated) in case the title contains dots:

list($number, $title) = explode('. ', $str, 2);
