I have a number of strings which contain words which are bunched together and I need to seperate them up.
For example
ThisWasCool – This Was Cool
MyHomeIsHere – My Home Is Here
Im slowly getting my head around regular expressions and I believe to do this I should use preg_replace. My problem is putting together the expression to find the match.
I have only got this far
preg_replace('~^[A-Z]~', " ", $string)
Each string contains a lot of words, but ONLY the first word contains bunched words so using my example above a string would be
"ThisWasCool to visit you again" – "This Was Cool to visit you again"
I have told it to start at the beginning, and look for capitals, but what I dont know how to do is
– restrict it only to the first word of each string
– how to reuse the capital letter in the replace part after the space

Problem
Your regex
'~^[A-Z]~'
will match only the first capital letter. Check out Meta Characters in the Pattern Syntax for more information.Your replacement is a newline character
'\n'
and not a space.Solution
Use this code:
The
(?<!\ )
is an assertion that will make sure we don't add a space before a capital letter that already has a space before it.
