php/jsp Riff1__js

Practicing the piano when the riff called a small piece of music, then I define the program's riff is a small piece of the program, put some of these days to write their own, later also long-term update, as their own accumulation and future programming reference.

1. Format URL, if no HTTP headers inserted HTTP header

<?php//add http head to URL function addhttphead (& $s) {$exist = Strstr ($s, "http://"); if (! $exist) $s = "htt p://". $s; }?>

2. Link MySQL Database

<?php $conn =mysql_connect ("IP", "username", "password"); mysql_select_db ("database name");?>

3. SELECT MySQL Database

$exec = "SELECT * from movie"; $result = mysql_query ($exec); while ($rs =mysql_fetch_object ($result)) {//access to each record, such as Echo $rs->name;}

4. WINDOWS Named pipe Communications (pipelines are established by other processes)

function Sendtoclient ($msg) {$fp = @fopen ("////.//pipe//tongxun", ' w+r+b '), @fwrite ($fp, $msg),//write $result = @fread ($fp, 256)//Read fclose ($FP); }

5. Judge check box result

function Isselect ($index, $select _tag) {for ($i =0; $i <count ($select _tag); $i + +) {if ($index = = $select _tag[$i]) return TRUE; return FALSE; }

6. Page token generation and processing

Generate page tokens to prevent duplicate submission of forms $pagecode = Mt_rand (0,10000000); $_session[' Code ' = $pagecode; ...///To obtain a token to operate the page if ($_session[' code '] = = $_post[' Pagecode ']) {//token meets} else//token not conforming

7. JSP take form content

Note here that IE has a innerhtml trap, the result needs to trim a bit.

$data = document.all. Table Id.rows (line number). Cells (column number). InnerHTML;
