Switching text after minus sign

[Mcod]

Hi there,

 

I need some help with modifying a string.

 

I always have strings that look like:

 

This is part two - This is part one

This is part four - This is part three

 

What I need is to switch the position which is separated by space minus sign space, so it returns:

 

This is part one - This is part two

This is part three - This is part four

 

Something like:

 

$string = "this is part two - this is part one";

 

after the code I am looking for ran, it would return:

 

$newstring = "this is part one - this is part two";

 

Any ideas how this could be done so it works for everything that is separated by space minus space?

 

Thank you for your time

Hi Mcod!

 

This regex will reverse your strings.

 

Match expression:

([^-]*?) -(.*)

 

Replace expression:

\2 - \1

 

Here is an example of preg_replace integration ($subject is your string):

$result = preg_replace('/([^-]*?) -(.*)/m', '\2 - \1', $subject);

 

Is this what you were looking for?
