PHP Include and Require function .
Welcome to PHP programming,
We can insert a contents of a file into a PHP file before the server executes it, with the
include() or require() function.
The two functions are identical in every way, except how they handle errors.
The include() function generates a warning but the script will continue execution.
The require() function generates a fatal error and the script execution will stop after the error.
These functions are used to create elements that can be reused on multiple pages.
This can save the developer a considerable amount of time.
The include() function
This function takes all the text in a specified file and copies it into the file that uses the
include function.
Let us write a PHP code
Save it in our server i.e., xampp/htdocs
To include header file in a page, use the include() function
Save this in our server i.e., xampp/htdocs
Run the code using the url http://localhost/phphome.php
This is how include() function works.
Let us see how include() function gives error messages if the wrong.php file doesnot exist
save this code in our server i.e, xampp/htdocs
Run this code using the url http://localhost/phpinclude.php
In This after the error is encountered further execution takes place.
The require() function
The require() function is identical to include(), except that it handles errors differently.
Let us write a PHP code
Save it in our server i.e, xampp/htdocs
Let us include the above code in the page
Save it in our server i.e., xampp/htdocs
Run the code using the url http://localhost/phphome1.php
This is how require() function works.
Let us see how require() function gives error messages if the wrong.php file doesnot exist
save the code in our server i.e., xampp/htdocs
run the code using the url http://localhost/phprequire.php
In this after the error is encountered further execution doesnot takes place.
Thank You.
