php array 分页,array分页
php array 分页,array分页
$array=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20");//规定要分页的数组
$page= $_GET['page'];
$r = $this->page($array,5,$page);
print_r($r);
exit();
foreach($r["source"] as $s){
echo $s;
}
function page($array,$pagesize,$current){
$_return=array();
$total=ceil(Count($array)/$pagesize);//求总页数
$prev=(($current-1) $next=(($current+1)>=$total ? $total:$current+1);//确定下一页,如果当前页是最后一页,点击下页显示最后一页
$current=($current>($total)?($total):$current);//当前页如果大于总页数,当前页为最后一页
$start=($current-1)*$pagesize;//分页显示时,应该从多少条信息开始读取
for($i=$start;$i array_push($_return,$array[$i]);//将该显示的信息放入数组 $_return 中
}
$pagearray["source"]=$_return;
$pagearray["page"]="first \">prev next end";//分页样式可跟据需要调整
return $pagearray;
}
$listArr = array_slice($array, ($page-1)*$pagesize, $pagesize, true);
$page 为页数
这种不建议使用php分页,因为数据已经完整了,出于优化显示效果的目的而分页的话可以采用js方式。因为页面跳转需要让访问者等待较长的时间,所以不推荐这样做。
通常的分页都是将数据库内容进行分页,比如需要显示100条,但是每次只显示10条,这样一个是展示起来较快,另一个主要的原因是减少数据库端的压力。
你这种可以简单的分开放在多个div里面,通过上一页下一页控制div的显示和隐藏就行了。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
