PHP
Functions
Define a function with function name($params) { ... },
and return a value if it should produce one.
Example: a greeting function
<?php
function greet($name) {
return "Hello, $name!";
}
echo greet("Chidi");
?>Hello, Chidi!Note that variables interpolate inside the returned string exactly the
same way they did in the Echo lesson, $name works inside a
double-quoted string whether it's a top-level variable or, as here, a
function parameter.
<?php
function greet($name) {
return "Hello, $name!";
}
echo greet("Chidi");
?>Hello, Chidi!
