Question

这段代码选择了一个包含3个索引的数组：

<?php var_dump($the_query1->posts); ?>

输出是3个索引的数组：

array(3) {
      [0]=>
      object(WP_Post)#4451 (24) {

检查当前索引是否在位置1的最佳方法是什么？我想返回一个布尔值来确定该元素应该变成<div class="col-sm-4">还是<div class="col-sm-3">，以防返回true。

我尝试过：

<?php var_dump($the_query1->posts[1] === true); ?>

但这将返回三遍false。我需要返回false，true，false。最简单的检查方法是什么？

使用foreach循环数据，并在数组键为1时执行匹配条件。

foreach ($the_query1->posts as $key => $value) {
    if($key == 1){
        echo '<div class="col-sm-3">';
    } else {
        echo '<div class="col-sm-4">';
    }
    echo '</div>';
}

检查PHP数组中的数组索引是否为1
