Here's a really simple example:
<?
// regular variable that exists outside any functions
$global_var = 5;
// we will pass this variable to the function
$passed_var = 7;
// define the function
function function_name ($passed_var){
// pull in any needed global variables not local or passed to the function
global $global_var;
// regular variable that exists only in this function
$local_var = 10;
// build up the html
$html = "Now inside function_name()...<br>\n";
// build up some more html
$html .= "\$global_var + \$local_var + \$passed_var = " . $global_var +
$local_var + $passed_var . "<br>\n";
// pass the $html back to the caller
return $html;
}
// call the function
echo function_name ($passed_var);
?>
Usually you wanna use funtions for code you intend to use multiple times.
