用递归addslashes函数转义数组
有个一个数组,可能是多维的,里面有些值带有特殊符号 比如“ 我用递归加addslashes()转义
没有达到效果 帮忙看看哪错了
$arr=array('ii"',array('one'=>'ec"','two'=>5));
function t(&$arr){
foreach($arr as $v){
if(is_string($v)){
$arr[]=addslashes($v);
}else{
t($v);
}
}
}
t($arr);
echo "
";<br>print_r($arr);<br>echo '';
前台页面是这么输出的

你自己对比下
$arr=array('ii"',array('one'=>'ec"','two'=>5),'aa"a');<br />function t(& $arr){<br /> foreach($arr as $k => $v){<br /> if(is_string($v)){<br /> $arr[$k] = addslashes($v);<br /> }else{<br /> $arr[$k] = t($v);<br /> }<br /> }<br /> return $arr;<br />}<br />t($arr);<br />echo "<pre class="brush:php;toolbar:false">";<br />print_r($arr);<br />echo '';
------解决方案--------------------
$arr = array('ii"',array('one'=>"ec'",'two'=>5));<br />array_walk_recursive($arr, function(&$v) { $v = addslashes($v);} );<br />print_r($arr);<br />
Array<br />(<br /> [0] => ii\"<br /> [1] => Array<br /> (<br /> [one] => ec\'<br /> [two] => 5<br /> )<br /><br />)<br /><br />
------解决方案--------------------
改成這樣就可以了。
<br />function t(&$arr){<br /> foreach($arr as $key=>$v){<br /> if(is_string($v)){<br /> $arr[$key]=addslashes($v);<br /> }else{<br /> t($arr[$key]);<br /> }<br /> }<br />}<br />
------解决方案--------------------
再改一下。

<br />function t(&$arr){<br /> foreach($arr as $key=>$v){<br /> if(is_array($v)){<br /> t($arr[$key]);<br /> }else{<br /> $arr[$key]=addslashes($v);<br /> }<br /> }<br />}<br /> <br />$arr=array('ii"',array('one'=>'ec"','two'=>'5'));<br />t($arr);<br /><br />print_r($arr);<br />

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
