Since the data inside the single-quoted string is not parsed for variable substitution, it’s always a better idea speed-wise to initialize a string with single quotes, unless you specifically need variable substitution

Sachin

• Jun 21st, 2014

Single quotes will print the statement as a literal but double quotes prints the value for the variables also.....

Single quotes for performance, no matter if there are variables or not!

Difference between require() and require_once():  require() includes and evaluates a specific file, while require_once() does that only if it has not been included before (on the same page).
So, require_once() is recommended to use when you want to include a file where you have a lot of functions for example. This way you make sure you don't include the file more times and you will not get the "function re-declared" error.

Difference between require() and include() is that require() produces a FATAL ERROR if the file you want to include is not found, while include() only produces a WARNING.

There is also include_once() which is the same as include(), but the difference between them is the same as the difference between require() and require_once().

aditya dhanraj

• Apr 29th, 2015

Require_once():-using this function we can access the data of another page once i. e we can not access the same page multiple times.

require():-using this function we can access the data of another page at the desire page multiple times i.e we can access the contents of same page multiple times.

Include() and require() dose same work.The difference is on error cheeking .Require () gives a fatal error when file cant load whereas include() gives a warning and continue to execute.

You have used the same name for both the files. Hence it by default replaces the file to the name when goes to next page.
