Question

I’m looking at some code that uses PATH_SEPARATOR. I don’t think this constant is explicitly defined anywhere but I could be wrong. Does anyone know if this is a native constant in PHP, and do other similar separators exist without needing to define? I’m trying to see if I can use LINE_SEPARATOR, PARAGRAPH_SEPARATOR, and such but nothing worked. How do I define these if I need to?

Answer 1

The documentation will yield all the answers you are looking for:

• Predefined Constants
• Magic Constants – “Constants” who’s value changes depending on where they are used…

So, looking there,

• DIRECTORY_SEPARATOR – The directory separator for the current OS (/ for Linux, \ for Windows, etc)
• PATH_SEPARATOR – You already saw that.
• PHP_EOL – The system’s new line format (\n for Linux, \r\n for Windows, etc)
• PHP_OS – The current operating system.
