I have text that goes like this: Id - Name: Age - Phone
500 - Antonio: Age: 35 years - phone 3681-08xx
Preferences: cycling, traveling.
1,500 - Rodrigo: Age: 20 years - phone 3685-40xx
Preferences: Play dance, read book.
I would like to put in the sentences beginning with numbers the information "Id:", to look like this:
ID: 500 - Antonio: Age: 35 years - phone 3681-08xx
Preferences: cycling, traveling.
ID: 1,500 - Rodrigo: Age: 20 years - phone 3685-40xx
Preferences: Play dance, read book.
How do I do this with preg_replace_callback?
