两种方式，可以直接改变当前值共享的内存位置，或者使用源数组访问该值.

Two ways, you can alter the memory location shared by the current value directly, or access the value using the source array.

// Memory reference
foreach ($bizaddarray as &$value) {
    $value = strip_tags(ucwords(strtolower($value)));
}
unset($value); # remove the reference

或

// Use source array
foreach ($bizaddarray as $key => $value) {
    $bizaddarray[$key] = strip_tags(ucwords(strtolower($value)));
}
