我有一个$阵列与存储在它的一些价值观。现在,如果我做的:
I have an $array with some values stored on it. Now, if I do :
$array=array();所有的值/索引中删除?或者,我需要在它之前使用未设置()?
all values/index are deleted? Or I need to use unset() before it?
推荐答案一个新阵列正在与创建阵列(),这新数组对象赋给变量 $阵列。
A new array is being created with array() and this new array object is assigned to the variable $array.
变量( $阵列)不再指向的原始的数组对象 - 因为PHP是一种垃圾回收的语言 - 的的原始的数组对象将有资格回收的如果(且仅当)的不再是强可从根对象。 (实际时间previous数组对象和对象包含它在实际删除取决于其他因素。)
The variable ($array) no longer points to the original array object -- and because PHP is a garbage collected language -- the original array object will be eligible for reclamation if (and only if) it is no longer strongly reachable from a root object. (The actual time the previous array object and objects it contained are actually deleted depends on other factors.)
快乐编码。
请参阅 PHP垃圾收集手册了解更多详细信息 - PHP使用混合GC(REF-计数和周期破)。
See PHP Garbage Collection Manual for more details -- PHP uses a hybrid GC (ref-count and cycle-breaking).
