PHP variable in variable
I have set an array in my config file that I use global in my functions.
This works fine, but now I want to pass the name of this array as a @param in my function.// in config file:
$album_type_arr = array("appartamento", "villa");
global $album_type_arr; // pull in from 开发者_Python百科db_config
echo $album_type_arr[0];
function buildmenu($name) {
$test = global $name . "_arr";
echo $test[0];
}
buildmenu("album_type");
You're looking for variable variables:
http://www.php.net/manual/en/language.variables.variable.php
function buildmenu($name) {
$test = $name . "_arr";
global ${$test};
echo ${$test}[0];
}
You can use "variable variables". This works:
function buildmenu($name) {
global ${$name. '_arr'};
$test = ${$name. '_arr'};
echo $test[0];
}
