我有两个函数，它们附加到钩子上，并在程序生命周期中的定义点或事件上执行。当我们想将一些返回值从一个函数调用传递到另一个函数，但不需要重复的函数调用或污染全局范围时，从函数和设计来看，什么是最好的方法。
这是，我希望有充分的文件记录的部分代码：
/**
* @array hookparams Hookparams array from both of function calls
*/
$hookparams = []; // initalized empty values
function hook_FunctionOne()
{
//do something, than save result in hookparams array
$hookparams['key'] = "Foo"; // return? But I can't call FunctionOne once more, and assign return value to temp variable
}
function hook_FunctionTwo(array $hookparams)
{
//do something with returned hookparams array form function, than save result in hookparams array again
$hookparams['key'] .= "Bar"; // Result is "FooBar";
}
// Both functions are called here
run_hook("HookPoint1", "hook_FunctionOne");
run_hook("HookPoint2", "hook_FunctionTwo");
通过引用将参数传递给函数节省了我的一天。这是完整的代码：
/**
* @array hookparams Hookparams array from both of function calls
*/
$hookparams = []; // initalized empty values
function hook_FunctionOne(&$hookparams)
{
//do something, than save result in hookparams array
return $hookparams['key'] = "Foo"; // return? But I can't call FunctionOne once more, and assign return value to temp variable
}
function hook_FunctionTwo(&$hookparams)
{
//do something with returned hookparams array form function, than save result in hookparams array again
return $hookparams['key'] .= "Bar"; // Result is "FooBar";
}
// Both functions are called here
echo hook_FunctionOne($hookparams); // First function call
echo hook_FunctionTwo($hookparams); // Second function call
echo "<pre>";
print_r($hookparams);
echo "</pre>"
