What’s the different between include and require?

[shophia]

Both are PHP syntax and used for including the files in the php files, however the difference is,

If the file is not found by require() syntax, it will reason a fatal error and end the execution of the script.
If the file is not found by include() syntax, a warning will be mattered, however execution will never end .

Basically, the two functions are implemented include and require the same: PHP will load the entire contents of the file include or require, no matter what the format. For content in php tags will be executed as normal php file. For content outside of php tags will be printed.

Different between include and require in PHP:
include("file.php"): if the file does not exist file.php it will automatically execute the script again.

require ("file.php"): if the file does not exist, it will stand always file.php and execute any script that does the following. Therefore require the file is the most important file.

include_one like include, however include_once include only one single time.

require_once requires only 1 time for loading and it will not call for next loadings.

I couldn't have said it better myself. Wonderful info.

I might just think about closing this thread.

Unlike include(), require() will always read in the target file, even if the line it's on never executes. If you want to conditionally include a file, use include(). The conditional statement won't affect the require(). However, if the line on which the require() occurs is not executed, neither will any of the code in the target file be executed.

oh php sounds so difficult but once you understand it is a very easy and strong language to start with
