PHP解析JSON数据,怎么增加一个判断,URL地址是否是图片
PHP解析JSON数据,如何增加一个判断,URL地址是否是图片?
我有一组JSON数据,我想通过PHP把他解析成HTML格式的内容。
其中Uri部分有的是照片,有的是链接。如何增加一个判断,是照片的输出,不是照片的为空。谢谢。
- PHP code
$data = json_decode($json); foreach ($data->results as $result) { if(!empty($result->Uri)){ echo '<img src="'.htmlspecialchars($result->Uri).'" />'; } }
------解决方案--------------------
大部分的图片链接都是以后缀jpg/gif/png等出现的
如果是urlwrite了话 那么你可以查看下他的命名规律来做filter
------解决方案--------------------
- PHP code
$imgs_arr = array( "jpg" , "jpeg" , "png" , "gif" );//图片的后缀 ,自己可以添加 $data = json_decode($json); foreach ($data->results as $result) { $ext = strtolower(end(explode(".",$result->Uri))); if( !empty($ext) && in_array($ext , $imgs_arr)){ echo '<img src="'.htmlspecialchars($result->Uri).'" />'; } }
