只是一个快速的新手PHP语法问题。
我有一个变量，让我们称之为$tabs，它总是包含一个由逗号分隔的数字字符串，如下所示：24,35,43,21
我还有一个变量，它是一个数组：
$args = array( post_type => page , post__in => array(27,19,29), order => ASC );
那当然是WordPress。我需要做的是将$tabs变量（数字）的内容放在数组中数字所在的位置。我对PHP相当陌生，只知道如何修改一些东西，但这一点我搞不清楚，不知道它的语法应该如何。
有人能帮忙吗？谢谢
$args[ post__in ] = array_merge($args[ post__in ], explode( , , $tabs));
让我们来解释一下我做了什么，这样你就可以了解一两件事：
explode( , , $tabs) splits a string into pieces at a separator and puts that pieces in an array.array_merge($arr1, $arr2) will merge the two arrays.$args[ post__in ] will access an array element specified by a key.请注意，在这种情况下，array_merge只会附加值，结果可能会出现重复的数字。要消除重复项，只需将合并封装在＜code＞array_unique
$args[ post__in ] = array_unique(array_merge($args[ post__in ], explode( , , $tabs)));
当然，当你只想用全新的数字替换这些数字时，最琐碎的情况是
$args[ post__in ] = explode(`,`, $tabs);
$args[post__in]=爆炸（“，”，$tab）
