php数组
后端开发-PHP问题
供求信息网设计源码,ubuntu系统鼠标跳动,python怎么优化爬虫,php如何使用循环生成随机数,湛江seo加盟lzw
推荐：《PHP视频教学》源码app下载 迅雷下载 迅雷下载,ubuntu有收费项目,tomcat直接访问图片,java爬虫结构,php源码查杀,中山市seo上词点击软件lzw
php 修改数据中某个元素值，其它元素值不变。威客类源码,vscode的sql插件,ubuntu切换jdk,tomcat配置测试页面,sqlite3保存视频包,ts文件名没有规律如何爬虫,php 链接传递参数,如何给商家做seo,中国古典风格网站,mx模板wplzw

foreach($pid_arr_t as $key=>$value){ $value['opid'] = 123; $pid_arr_t[$key] = $value; }只有修改opid的元素值.
