无知的我接触到了PHP,学习了PHP并尝试做了第一个比较合适的PHP项目。同时我正在不断优化自己写笔记的方法
目的是 为了解决第一次学习PHP的人能够快速通过可入手的完整的项目来串联知识点构建良好的体系以及提升运用这些知识的能力
在sfkbbs>inc>创建config,inc.php:
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASSWORD', '123456');
define('DB_DATABASE', 'sfkbbs');
define('DB_PORT', '3306');
header('Content-type:text/html;charset=utf-8');
在sfkbbs>inc>创建mysql.inc.php:
<?php //连接数据库,如果连接错误,则输出错误信息 //返回连接钥匙 function connect($host=DB_HOST,$user=DB_USER,$password=DB_PASSWORD,$database=DB_DATABASE,$post=DB_PORT){ $link = @mysqli_connect($host,$user,$password,$database,$post); if(mysqli_connect_errno()){ exit(mysqli_connect_error()); } mysqli_set_charset($link, 'utf8'); return $link; } //执行一条SQL语句 //返回结果集 function execute($link,$query){ $result = mysqli_query($link, $query); if(mysqli_errno($link)){ exit(mysqli_error($link)); } return $result; } //一次性执行多条sql语句,如果有错误则输出错误信息 //传入:连接钥匙,sql语句数组;引用地传入错误信息 //返回查询结果集 function execute_multi($link,$arr_sqls,&$error){ $sqls=implode(';',$arr_sqls).';'; if(mysqli_multi_query($link,$sqls)){ $data=array(); $i=0;//计数 do { if($result=mysqli_store_result($link)){ $data[$i]=mysqli_fetch_all($result); mysqli_free_result($result); }else{ $data[$i]=null; } $i++; if(!mysqli_more_results($link)) break; }while (mysqli_next_result($link)); if($i==count($arr_sqls)){ return $data; }else{ $error="sql语句执行失败:<br /> 数组下标为{$i}的语句:{$arr_sqls[$i]}执行错误<br /> 错误原因:".mysqli_error($link); return false; } }else{ $error='执行失败!请检查首条语句是否正确!<br />可能的错误原因:'.mysqli_error($link); return false; } } //获取记录数 function num($link,$sql_count){ $result=execute($link,$sql_count); $count=mysqli_fetch_row($result); return $count[0]; } //结果集语句数量 function execute_num($link,$sql_count){ $execute_result = execute($link, $sql_count); $execute_num = mysqli_fetch_row($execute_result); return $execute_num[0]; } //转义操作!!!!!!!!!!递归函数的应用的一个实例!!!!!!! function escapes($link, $data){ if (is_string($data)){ $data = mysqli_real_escape_string($link, $data); return $data; } if (is_array($data)){ foreach ($data as $key=>$val){ $data[$key] = escapes($link, $val); } } return $data; } //关闭数据库 function close($link){ mysqli_close($link); }
在sfkbbs>inc>创建tool.php
<?php function skip($url,$class,$message){ //!!!注意定界符里面不能解析php标签 //!!!!注意如何在meta里面设置自动跳转语法 $html = <<<A <!DOCTYPE html> <html lang="zh-CN"> <head> <meta charset="utf-8" /> <meta http-equiv="refresh" content="3; URL={$url}"/> <title>正在跳转</title> <link rel="stylesheet" type="text/css" href="style/remind.css" /> </head> <body> <div class="notice"><span class="pic {$class}"></span>{$message}<a href="{$url}">3秒后自动跳转</div> </body> </html> A; echo $html; exit;//不写括号也可以?对 } ?>
在sfkbbs>admin>创建son_module.php文件
任务:显示子版块数据中的所有内容
解决:遍历查询结果集
<?php include_once '../inc/config.inc.php';//此前不能添加任何信息? include_once '../inc/mysql.inc.php'; $link = connect(); $template['title'] = '父板块'; ?> <?php include 'inc/header.inc.php';?> <div id="main"> <div class="title">功能说明</div> <table class="list"> <tr> <th>排序</th> <th>版块名称</th> <th>所属父版块</th> <th>版主</th> <th>操作</th> </tr> <?php $query = "select * from sfk_son_module"; $result = execute($link, $query); while ($data = mysqli_fetch_assoc($result)){ $html = <<<A <tr> <td><input class="sort" type="text" name="sort" /></td> <td>{$data["module_name"]}[id:{$data["id"]}]</td> <td> <a href="#">[访问]</a> <a href="#">[编辑]</a> <a href="#">[删除]</a> </td> </tr> A; echo $html; } ?> </table> </div> <?php include 'inc/footer.inc.php';?>
在sfkbbs>admin>创建son_module_delete.php
-需求分析以及实现:
1.点击删除按钮,跳转到二次确认页面。
2.在二次确认页面,
配置二次确认页面:利用地址传参:1.传入 m e s s a g e u r l (提示信息) 2. message_url(提示信息) 2. messageurl(提示信息)2.return_url(返回的地址)
点击确认删除按钮:跳转到后台的子版块删除页面,根据传入的id值,执行数据库删除操作。
点击取消按钮:不删除。
点击最终结果:1.自动跳转回子版块展示页面 (需要重新查询数据库,而更新页面)
<?php include_once '../inc/config.inc.php';//此前不能添加任何信息? include_once '../inc/mysql.inc.php'; $link = connect(); $template['title'] = '父板块'; ?> <?php include 'inc/header.inc.php';?> <div id="main"> <div class="title">功能说明</div> <table class="list"> <tr> <th>排序</th> <th>版块名称</th> <th>所属父版块</th> <th>版主</th> <th>操作</th> </tr> <?php $query = "select * from sfk_son_module"; $result = execute($link, $query); while ($data = mysqli_fetch_assoc($result)){ //通过传递url来让目的页面可以跳转传递过来的指定页面 //注意!!!为了返回url参数注入,不能直接传递【url+url参数】,需要以下两种办法传递 $delete_url = urlencode("son_module_delete.php?id={$data['id']}");//如果这边用字符串形式设置url参数,要注意双引号入住 $return_url = urlencode($_SERVER['REQUEST_URI']);//!!!获取当前页面的url!!! $message_url = urldecode("{$data["module_name"]}"); $confirm_ulr = "confirm.php?delete_url={$delete_url}&return_url={$return_url}&message_url={$message_url}"; //!!!!记住这种定界符写法!!!! $html = <<<A <tr> <td><input class="sort" type="text" name="sort" /></td> <td>{$data["module_name"]}[id:{$data["id"]}]</td> <td> <a href="#">[访问]</a> <a href="son_module_update.php?id={$data['id']}">[编辑]</a> <a href="$confirm_ulr">[删除]</a> </td> </tr> A; echo $html; } ?> </table> </div> <?php include 'inc/footer.inc.php';?>
在sfkbbs>admin>father_module_delete.php 添加下面配置
**-需求:**当父板块存在子板块时,作删除操作,需要二次确认。
<?php include_once '../inc/config.inc.php'; include_once '../inc/mysql.inc.php'; include_once '../inc/tool.php'; $url = "father_module.php"; if(!isset($_GET["id"]) || !is_numeric($_GET["id"])){//$_GET["id"]其实就是一个以字符串为索引的数组 skip($url, "error", "id参数不存在!"); }//!!!注意!!!在此处如果不设置停止,其会继续执行下面语句,所以需要停止,停止方式有多种看详情!!!!! $link = connect(); /** * 若父板块存在子板块(若子板块存在父板块) * 则当删除该父板块时,需要二次确认。 */ $query = "select * from sfk_son_module where father_module_id = {$_GET['id']}"; $result = execute($link, $query); if (mysqli_num_rows($result)){ skip($url, 'error', '该父板块存在子板块!需要先删除对应子版块!'); } $query = "delete from sfk_father_module where id = {$_GET['id']}"; execute($link, $query); if (mysqli_affected_rows($link) == 1){ skip($url, "ok", "恭喜删除成功!"); }else { skip($url, "error", "删除失败!"); } //!!!!url地址传递参数,传递的其实是字符串,在其显示上省略了双引号

1.在sfkbbs>font>导入字体包
2.在sfkbbs>inc>创建vcode.inc.php:
<?php /** * * @param number $width 验证码长度 * @param number $height 验证码高度 * @param number $fontSize 验证码字体大小 * @param number $countElement 验证码字符个数 * @param number $countPixel 验证码背景的点的数量 * @param number $countLine 画的线的数量 * @return string */ function vcode($width=120,$height=40,$fontSize=30,$countElement=5,$countPixel=100,$countLine=4){ header('Content-type:image/jpeg'); $element=array('a','b','c','d','e','f','g','h','i','j','k','m','n','o','p','q','r','s','t','u','v','w','x','y','z'); $string=''; /** * 在验证码中,显示字符的个数 */ for ($i=0;$i<$countElement;$i++){ $string.=$element[rand(0,count($element)-1)]; } $img=imagecreatetruecolor($width, $height); $colorBg=imagecolorallocate($img,rand(200,255),rand(200,255),rand(200,255)); $colorBorder=imagecolorallocate($img,rand(200,255),rand(200,255),rand(200,255)); $colorString=imagecolorallocate($img,rand(10,100),rand(10,100),rand(10,100)); imagefill($img,0,0,$colorBg); /** * 在验证码中,背景的点的数量 */ for($i=0;$i<$countPixel;$i++){ imagesetpixel($img,rand(0,$width-1),rand(0,$height-1),imagecolorallocate($img,rand(100,200),rand(100,200),rand(100,200))); } /** * 画的线的数量 */ for($i=0;$i<$countLine;$i++){ imageline($img,rand(0,$width/2),rand(0,$height),rand($width/2,$width),rand(0,$height),imagecolorallocate($img,rand(100,200),rand(100,200),rand(100,200))); } //imagestring($img,5,0,0,'abcd',$colorString); /** * 字;验证码字体大小;起始位置; */ imagettftext($img,$fontSize,rand(-5,5),rand(5,15),rand(30,35),$colorString,'font/ManyGifts.ttf',$string); imagejpeg($img); imagedestroy($img); return $string; } ?>
可能遇到问题:验证码只有一个小方格
法1:用绝对路径引入字体文件as:
//imagestring($img,5,0,0,'abcd',$colorString);
/**
* 字;验证码字体大小;起始位置;
*/
putenv("GDFONTPATH".realpath("."));
imagettftext($img,$fontSize,rand(-5,5),rand(5,15),rand(30,35),$colorString,'D:\300IT\PHP\Wamp64\www\sfkbbs\font\ManyGifts.ttf',$string);
imagejpeg($img);
imagedestroy($img);
return $string;
法2:相对路径转化为绝对路径,但在该文件中使用的其实还是相对路径as:
//imagestring($img,5,0,0,'abcd',$colorString);
/**
* 字;验证码字体大小;起始位置;
*/
//相对路径转化为绝对路径,但在该文件中使用的其实还是相对路径。
$realpath = realpath("font\ManyGifts.ttf");
imagettftext($img,$fontSize,rand(-5,5),rand(5,15),rand(30,35),$colorString,$realpath,$string);
imagejpeg($img);
imagedestroy($img);
/**
* 返回验证码内容
*/
return $string;

功能:通用的分页函数
细节:
如果父版块没有子版块不做分页,
若没有这个判断,则可能分页的头部为以前设置的-1,而导致sql语句错误
