(PHP 5, PHP 7, PHP 8)
ArrayAccess::offsetSet — 設(shè)置一個(gè)偏移位置的值
offset待設(shè)置的偏移位置。
value需要設(shè)置的值。
沒有返回值。
注意:
如果另一個(gè)值不可用，那么
offset參數(shù)將被設(shè)置為null，就像下面的例子。<?php
$arrayaccess[] = "first value";
$arrayaccess[] = "second value";
print_r($arrayaccess);
?>以上例程會(huì)輸出：
Array ( [0] => first value [1] => second value )
注意:
This function is not called in assignments by reference and otherwise indirect changes to array dimensions overloaded with ArrayAccess (indirect in the sense they are made not by changing the dimension directly, but by changing a sub-dimension or sub-property or assigning the array dimension by reference to another variable). 而是調(diào)用 ArrayAccess::offsetGet()。 只有該方法通過引用返回，操作才會(huì)成功。
