Main Content: describes the Image Upload process, involving PHP and JQuery;

1. Read the configuration file and connect to the MySQL database;

The configuration file mainly includes the user name and password;

3-5.php

<? Php/** version: 20141108 * // ** defines a constant */define ("EQUAL", "="); define ("SPACE ",""); function get_content ($ file) {if (! File_exists ($ file) return false; return file_get_contents ($ file);} function get_config ($ str, $ ini, $ type = "string ") {if ($ type = "int") {$ config = preg_match ("/". preg_quote ($ ini ). "= (. *);/", $ str, $ res); if ($ config = 0) return false;} else {$ config = preg_match ("/". preg_quote ($ ini ). "= \"(. *) \ ";/", $ str, $ res); if ($ config = 0) return false;} $ result = explode (EQUAL, $ res [0]); return preg_replace ("/(\" | \ '| ;)/" , SPACE, $ result [1]) ;}?>

2. Connect to the MySQL database;

The odbc class provided by PHP is used here;

First install the data source driver, class such as mysql-connector-odbc-5.3.4-win32; then in ODBC data source management where the configuration is OK.

2.1 database write connection

<?php/** version : 20141109* made dy : neojos*/include_once("3-5.php");class dbSource{function __construct(){$dbString=get_content("config.ini");$server=get_config($dbString,"server");echo $dbname=get_config($dbString,"userName");echo $dbpwd=get_config($dbString,"password");odbc_connect("DRIVER={MySQL ODBC 5.3 ANSI Driver};",$dbname,$dbpwd) or handle_error("",odbc_error()); }function handle_error($user_error_message,$system_error_message){header("Location:3-6.php?"."error_message={$user_error_message}&"."system_error={$system_error_message}");exit();}}$db=new dbSource();?>
