脚本

数据库连接

<?php
class mysql_obj{
   
    protected   $mysql = array (    //可设置参数
         "ip" => "",
         "usr" => "root",

    {

                "count"
                );
        $link = mysql_connect($this->mysql['ip'], $this->mysql['usr'], $this->mysql['pwd']);
        mysql_query("set names ’utf8’ ");  
        mysql_query("set character_set_client=utf8");  
        mysql_query("set character_set_results=utf8");
        mysql_select_db($this->mysql['database'], $link);
        $limits =  $inputs['num'];
        $start = ($inputs['page'] - 1)*$inputs['num'];
        $orderby = $inputs['orderby'];
        if(($condition['orderby'] == 1) and ($condition['where'] == 1))
        {
            $result_count = mysql_query("SELECT * FROM $table  where $row=$key", $link);
            $count = mysql_num_rows($result_count);
            mysql_free_result($result_count);
            $result = mysql_query("SELECT * FROM $table  where $row=$key  order by $orderby desc LIMIT $start,$limits", $link);
        }
        elseif(($condition['orderby'] == 0) and ($condition['where'] == 1))
        {
            $result_count = mysql_query("SELECT * FROM $table  where $row=$key", $link);
            $count = mysql_num_rows($result_count);
            mysql_free_result($result_count);
            $result = mysql_query("SELECT * FROM $table  where $row=$key LIMIT $start,$limits", $link);
        }
        elseif(($condition['orderby'] == 1) and ($condition['where'] == 0))
        {
            $result_count = mysql_query("SELECT * FROM $table", $link);
            $count = mysql_num_rows($result_count);
            mysql_free_result($result_count);
            $result = mysql_query("SELECT * FROM $table order by $orderby desc LIMIT $start,$limits", $link);
        }
       
        else
        {
            $result_count = mysql_query("SELECT * FROM $table", $link);
            $count = mysql_num_rows($result_count);
            mysql_free_result($result_count);
            $result = mysql_query("SELECT * FROM $table LIMIT $start,$limits ", $link);
        }
        $back['result'] = $result;
        $back['count'] = $count;
        return $back;
    }


    function close($result)
    {
        mysql_free_result($result);
        // 关闭连接
        mysql_close();  
    }
}
?>

　

字符串替换 json特殊字符处理

<?php
function string_deal($text)
{
    $text = str_replace("\n","",$text);
    $text=str_replace("\n","",$text);
    $text=str_replace("\r","",$text);
    $text=str_replace("\r\n","",$text);
    $text=str_replace("\"","\\\"",$text);
    return $text;
}
?>

　　

判断输入是否自由数字

<?php                                                                           
function checkVS($str)
{
    //返回结果为1只有数字,2只有字符,3两者都有
    $a=0;
    $b=0;
    for($i=0; $i<strlen($str);$i++)
    {
        $v=ord(substr($str,$i,1));
        if($v>=48 and $v<=57)
        {
            $a=1;
        }
        else
        {
            $b=2;
        }
    }
return $a+$b;
}
?>
