PHP: Adding space to a string with lowercaseUppercase scenario including numbers - php

Question

I have a string:
Baths: 2 full, 1 halfBuilt in 1990Views since listing: 1,845All time views: 2,00013 shoppers saved this homeHOA Fee: $399/moLaundry: In UnitParking: Carport, Garage - Detached, 2 spaces, 314 sqftLast sold: Apr 2011
I'm trying to make the above string more readable - so if you noticed there are no spaces in between new information. I have bold the above areas. What I noticed though is it ends with a smaller case letter then new information starts with an upper case.
Example: halfBuilt or 1,845All, etc. So my idea to make this readable is to add space in between them. So how do we do this in php and maybe regex? Thanks!

Answer 1

It seems like you want to break when letters/numbers run into an Uppercase letter. If that is this case this work:
/([a-z\d]+)([A-Z])/

PHP Usage:
$string = "Baths: 2 full, 1 **halfBuilt in 1990Views** since listing: **1,845All time views**: 2,00013 shoppers saved this **homeHOA Fee:** $399/moLaundry: **In UnitParking:** Carport, Garage - Detached, 2 spaces, **314 sqftLast** sold: Apr 2011";
$regex = '/([a-z\d]+)([A-Z])/';
echo preg_replace($regex, '$1 $2', $string);
Output:
Baths: 2 full, 1 half Built in 1990 Views since listing: 1,845 All time views: 2,00013 shoppers saved this home HOA Fee: $399/mo Laundry: In Unit Parking: Carport, Garage - Detached, 2 spaces, 314 sqft Last sold: Apr 2011

Answer 2

This should do:
$string = preg_replace("/([a-z0-9])([A-Z])/", "$1 $2", $string);
echo $string;
// => "Baths: 2 full, 1 half Built in 1990 Views since listing: 1,845 All time views: 2,00013 shoppers saved this home HOA Fee: $399/mo Laundry: In Unit Parking: Carport, Garage - Detached, 2 spaces, 314 sqft Last sold: Apr 2011"
