PHP - 在任何字母之前删除任何数字

Question

I am processing addresses, but I just want to remove the Street Number, eg

123 Fake St

I use the following regular expression /[^a-z ]/i' which works fine and results in

Fake St

However sometimes I have addresses such as

M4 Western Distributor Fwy

How would I keep the M4 part? Because if I run my regular expression it turns into

M Western Distributor Fwy

Any help would be appreciated, cheers

Answer 1

Try

/^[0-9 ]+(?=[^\d]+)/i

This matches all numbers that is followed by anything other than numbers, test:

$subject = '123 Fake St';
var_dump(preg_replace('/^[0-9 ]+(?=[^\d]+)/i', '', $subject));

$subject = 'M4 Western Distributor Fwy';
var_dump(preg_replace('/^[0-9 ]+(?=[^\d]+)/i', '', $subject));

Output:

string(7) "Fake St"
string(26) "M4 Western Distributor Fwy"
