PHP在更多函数之间传递变量

Question

I have about 30 variables that I need to pass to 3 functions e.g.

displayform() - where some form data is pulled out from DB and some needs to be entered into the form.

checkform() - which checks if all data is entered properly.

errors() - this will display errors (if any)

processform()- this process all data and store them to DB

Now I am using GLOBAL $variable; to pass those variables between functions, but than I have to declare each variable as global at the function begin and that results in a big file, so I just want to know is there a way to declare variables as globals (preferably only once) so that all functions can use them ?

Answer 1

You can try putting all the variables into an associative array and just passing this array between functions, like:

$omgArray = array();
$omgArray['lolVar1'] = lolVar1;
$omgArray['wowVar3'] = wowVar3;

yeaaaFunction($omgArray);

function yeaaaFunction($omgArray){
    echo $omgArray['lolVar1'] . $omgArray['wowVar3'];
}
