Difference between Language Construct & Functions: *Language Constructs* Constructs are elements that are built-into the language and, therefore, follow special rules. Perhaps the most common of them is the echo statement, which allows you to write data to the script’s output: echo 10; // will output 10 It’s important to understand that echo is not a function and, as such, it does not have a return value. If you need to output data through a function, you can use print() instead: echo 10;print (10); Another very important construct is die(), which is itself an alias of exit(). It allows you to terminate the script’s output and either output a string or return a numeric status to the process that called the script.
