Break a sentence in two parts on first occurrence of a a number

Question

I am in a situation that iIneed to break the line 'Havenlaan 86C Bus 12' into two parts

$str = 'Havenlaan 86C Bus 12'; 
$regex = '/[ ^\d]/';
$flags = PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY;
$exploded = preg_split( $regex,$str, 2, $flags);
print_r($exploded);

The above code sucessfully does the job and the out out is below.

1. Havenlaan

2. 86C Bus 12

BUT when I change the string to $str = 'Havenlaan ABC 86C Bus 12';

I get

1. Havenlaan
2. ABC 86C Bus 12

What I need is

1. Havenlaan ABC

2. 86C Bus 12

ie. first output should be pure string and second one should start with a number and can be followed by characters.

Answer 1

You can use lookahead

$regex = '/(?=\d)/';

This would split at the first occurrence of a digit (with the limit specified as 2).

Answer 2

If you just split twice, use /(?=\d)/

Answer 3

/ \d/ works as a delimiter.

[ ^\d] matches only a single character of either a space or ^\d not-a-digit.
