Question

我正在尝试打印此单词按查询，但该变量在该数组中不起作用（这些数字只是示例）。它只取第一个数字53而不是其他数字。

$catfeaturenumbers = '53,57,4294,71';
$categoryfeatured = array($catfeaturenumbers);
$featured = array(
'post__in' => $categoryfeatured
);

Answer 1

我想你想要的东西如下： -

<?php

$catfeaturenumbers = '53,57,4294,71';

// create an array through explode

$categoryfeatured = explode(',',$catfeaturenumbers);

echo "<pre/>";print_r($categoryfeatured); // print array to check
$featured = array(
 'post__in' => $categoryfeatured
);

注意： - 如果您想将原始字符串用于IN QUERY（示例SELECT * FROM <table> WHERE id IN (your original string data)），请执行以下操作： -

$categoryfeatured = "'".implode("','",explode(',',$catfeaturenumbers))."'";

echo  $categoryfeatured;
