数据放入数据库和取出来显示在页面需要注意什么
入库时
$str=addslashes($str);
$sql=\"insert into `tab` (`content`) values(\'$str\')\";
出库时
$str=stripslashes($str);
显示时
$str=htmlspecialchars(nl2br($str)) ;

//--标题,名字等字段入库处理(去首尾空格)
functiontrans_string_trim($str){
$str=trim($str);
$str=eregi_replace("'","''",$str);
$str=stripslashes($str);
return$str;
}
//--文章入库处理,即textarea字段;
functiontrans_string($str){
$str=eregi_replace("'","''",$str);
$str=stripslashes($str);
return$str;
}
//--从库中显示在表单中;在text中以trans转换,在textarea中,无需转换,直接显示
//--显示在WEB页面,过滤HTML代码;包括链接地址
functiontrans($string){
$string=htmlspecialchars($string);
$string=ereg_replace(chr(10),"
",$string);
$string=ereg_replace(chr(32),"",$string);
return$string; 
}
//--显示在WEB页面,不过滤HTML代码;
functiontrans_web($string){
$string=ereg_replace(chr(10),"
",$string);
$string=ereg_replace(chr(32),"",$string);
return$string; 
}
//--显示在WEB页面,过滤HTML代码及头尾空格,主要用于显示用户昵称
functiontrans_trim($string){
$string=trim($string);
$string=htmlspecialchars($string);
$string=ereg_replace(chr(10),"
",$string);
$string=ereg_replace(chr(32),"",$string);
return$string; 
}
//--显示在span中;
functiontrans_span($string){
$string=ereg_replace(chr(10),"\n",$string);
$string=ereg_replace(chr(32),"",$string);
$string=ereg_replace('"',""",$string);
return$string; 
}
//--在WEB上显示cookie,过滤html
functiontrans_cookie($str){
$str=trans($str);
$str=stripslashes($str);
$str=eregi_replace("''","'",$str);
return$str;
}
?>
