我尝试了以下代码，但它不起作用

@foreach ($prop as $pc1)

<?php 
echo explode("', '",'"'.$pc1['image_names'].'"');
?>
@endforeach

Answer 1

• 分隔符中没有空间
• 无需引用搜索字符串
• 由于explode()返回一个array，您需要第一个条目来获得图像字符串[0]

请仔细查看explode文档

@foreach ($prop as $pc1)

<?php 
echo explode(',', $pc1['image_names'])[0];
?>
@endforeach
