PHP多个数组遍历后的字符串加CSS格式后再随机输出。
$a='长颈鹿,大象,小猫,老虎,';/*此段字符颜色红色,字号12*/
$b='兔子,猫肉,羊肉,牛肉,';/*此段字符颜色紫色,字号16*/
$c='你好,谢谢,再见,很好,';/*此段字符颜色黄色,字号20*/
/*三段字符串,分别与中间逗号分割。用以下一步的分割成数组*/
$aa=explode(",",$a.$b.$c);
/*数组后,然后我想的是用array_rand()函数,然后遍历出随机排列的字符串*/
现在的问题是,如何将$a $b $c,这三组字符串分别设定好CSS颜色,文字大小。然后汇总在一起,再随机排列输出。
------解决方案--------------------
再试试这个,看看效果
header('content-type:text/html; charset=utf-8');
$arr = array('长颈鹿', '大象', '小猫', '老虎', '兔子', '猫肉', '羊肉', '牛肉', '你好', '谢谢', '再见', '很好');
$style_arr = array();
foreach($arr as $val)
{
$font_size = rand(12, 20).'px';
$font_color = 'rgb'.'('.rand(0, 255).','.rand(0, 255).','.rand(0, 255).')';
$style = '';
$font = '';
$style_arr[] = $style.$val.$font;
}
shuffle($style_arr);
foreach($style_arr as $val2)
{
echo $val2.' ';
}
------解决方案--------------------
- PHP code
$a = '长颈鹿,大象,小猫,老虎';$b = '兔子,猫肉,羊肉,牛肉';$c = '你好,谢谢,再见,很好';echo .c1 { background:red; font-size:12px; }.c2 { background:green; font-size:16px; }.c3 { background:orange; font-size:20px; }STYLE;$aa = explode(',', $a);array_walk($aa, 'func', 'c1');$bb = explode(',', $b);array_walk($bb, 'func', 'c2');$cc = explode(',', $c);array_walk($cc, 'func', 'c3');$ar = array_merge($aa, $bb, $cc);shuffle($ar);echo join('', $ar);function func(&$item, $key, $param) { $item = "<span class="$param">$item</span>";}<div class="clear"> </div>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
