使用php中的编辑和删除图像删除和更新行(Delete and update row using edit and delete image in php)

 这是我的branch.php页面，我想在用户点击php中的编辑和删除图像时删除和更新行，直接在表中删除或更新该行。但是这两行都没有更新或删除。 
 

<?php
$a1=mysql_connect('localhost','root1','oec@123');
$b1=mysql_select_db('rms',$a1);

 Twitter上的用户向我指出了一个PDF，我无法相信我以前没有找到过

 简而言之，有必要创建一个批处理文件来在Perforce中启动外部差异和合并工具。 

A user on twitter pointed me at a PDF which I can't believe I hadn't previously managed to find

In short it's necessary to create a batch file to launch external diff and merge tools in Perforce.
