PHP数据的提交与过滤基本操作实例详解

本文实例讲述了PHP数据的提交与过滤基本操作。分享给大家供大家参考,具体如下:

1、PHP提交数据过滤的基本原则

1)提交变量进数据库时,我们必须使用addslashes()进行过滤,像我们的注入问题,一个addslashes()也就搞定了。其实在涉及到变量取值时,intval()函数对字符串的过滤也是个不错的选择。

2)在PHP.ini中开启magic_quotes_gpc和magic_quotes_runtime。magic_quotes_gpc可以把get,post,cookie里的引号变为斜杠。 magic_quotes_runtime对于进出数据库的数据可以起到格式话的作用。其实,早在以前注入很疯狂时,这个参数就很流行了。

3)在使用系统函数时,必须使用escapeshellarg(),escapeshellcmd()参数去过滤,这样你也就可以放心的使用系统函数

4)对于跨站,strip_tags(),htmlspecialchars()两个参数都不错,对于用户提交的的带有html和PHP标记都将进行转换。比如尖括号"<"就将转化为 "<"这样无害的字符。

PHP;"> $new = htmlspecialchars("Test",ENT_QUOTES); strip_tags($text,);

5)对于相关函数的过滤,就像先前的include(),unlink,fopen()等等,只要你把你所要执行操作的变量指定好或者对相关字符过滤严密,我想

这样也就无懈可击了。

2、PHP简单的数据过滤

1)入库: trim($str),addslashes($str)

2)出库: stripslashes($str)

3)显示: htmlspecialchars(nl2br($str))

PHP;"> $val) $string[$key] = new_addslashes($val); return $string; } /** * 返回经stripslashes处理过的字符串或数组 * @param $string 需要处理的字符串或数组 * @return mixed */ function new_stripslashes($string) { if(!is_array($string)) return stripslashes($string); foreach($string as $key => $val) $string[$key] = new_stripslashes($val); return $string; } /** * 返回经htmlspecialchars处理过的字符串或数组 * @param $obj 需要处理的字符串或数组 * @return mixed */ function new_html_special_chars($string) { $encoding = 'utf-8'; if(strtolower(CHARSET)=='gbk') $encoding = 'ISO-8859-15'; if(!is_array($string)) return htmlspecialchars($string,ENT_QUOTES,$encoding); foreach($string as $key => $val) $string[$key] = new_html_special_chars($val); return $string; } function new_html_entity_decode($string) { $encoding = 'utf-8'; if(strtolower(CHARSET)=='gbk') $encoding = 'ISO-8859-15'; return html_entity_decode($string,$encoding); } function new_htmlentities($string) { $encoding = 'utf-8'; if(strtolower(CHARSET)=='gbk') $encoding = 'ISO-8859-15'; return htmlentities($string,$encoding); } /** * 安全过滤函数 * * @param $string * @return string */ function safe_replace($string) { $string = str_replace('%20','',$string); $string = str_replace('%27',$string); $string = str_replace('%2527',$string); $string = str_replace('*',$string); $string = str_replace('"','"',$string); $string = str_replace("'",$string); $string = str_replace(';',$string); $string = str_replace('<','<',$string); $string = str_replace('>','>',$string); $string = str_replace("{",$string); $string = str_replace('}',$string); $string = str_replace('\\',$string); return $string; } /** * xss过滤函数 * * @param $string * @return string */ function remove_xss($string) { $string = preg_replace('/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F]+/S',$string); $parm1 = Array('javascript','vbscript','expression','applet','Meta','xml','blink','link','script','embed','object','iframe','frame','frameset','ilayer','layer','bgsound','title','base'); $parm2 = Array('onabort','onactivate','onafterprint','onafterupdate','onbeforeactivate','onbeforecopy','onbeforecut','onbeforedeactivate','onbeforeeditfocus','onbeforepaste','onbeforeprint','onbeforeunload','onbeforeupdate','onblur','onbounce','oncellchange','onchange','onclick','oncontextmenu','oncontrolselect','oncopy','oncut','ondataavailable','ondatasetchanged','ondatasetcomplete','ondblclick','ondeactivate','ondrag','ondragend','ondragenter','ondragleave','ondragover','ondragstart','ondrop','onerror','onerrorupdate','onfilterchange','onfinish','onfocus','onfocusin','onfocusout','onhelp','onkeydown','onkeypress','onkeyup','onlayoutcomplete','onload','onlosecapture','onmousedown','onmouseenter','onmouseleave','onmousemove','onmouSEOut','onmouSEOver','onmouseup','onmousewheel','onmove','onmoveend','onmovestart','onpaste','onpropertychange','onreadystatechange','onreset','onresize','onresizeend','onresizestart','onrowenter','onrowexit','onrowsdelete','onrowsinserted','onscroll','onselect','onselectionchange','onselectstart','onstart','onstop','onsubmit','onunload'); $parm = array_merge($parm1,$parm2); for ($i = 0; $i < sizeof($parm); $i++) { $pattern = '/'; for ($j = 0; $j < strlen($parm[$i]); $j++) { if ($j > 0) { $pattern .= '('; $pattern .= '(&#[x|X]0([9][a][b]);?)?'; $pattern .= '|(�([9][10][13]);?)?'; $pattern .= ')?'; } $pattern .= $parm[$i][$j]; } $pattern .= '/i'; $string = preg_replace($pattern,' ',$string); } return $string; } /** * 过滤ASCII码从0-28的控制字符 * @return String */ function trim_unsafe_control_chars($str) { $rule = '/[' . chr ( 1 ) .
