代码如下
foreach ($url as $val){ if ($netbot->fetchlinks($val)){ $urlarray[] = $netbot->results; }else{ echo "error :".$netbot->error; exit; }}
这里的$url是一个数组,存放地址
通过snoopy的方法, $netbot->fetchlinks($val)来获取这个url的所有link
那么,我想把所有的link放在一个数组中
$netbot->results 返回的是一个一维数组
现在的问题是: $urlarray[] = $netbot->results;
这种方式赋值,会获得一个多维数组
里面的link只有他第一次访问url的links
我想让这个$urlarray下标自动转移.
在获取第二个url的时候,赋值时,可以继承上面的下标, 从而将$urlarray转化为1维数组,
这该如何实现呢?
回复讨论(解决方案)
if条件里面再循环?
foreach($netbot->results as $v){
$urlarray[] = $v;
}
先不管 $netbot->results 取得的是什么
你在 $netbot->fetchlinks($val) 失败后就 exit 了
那么 $url 中后续的 $val 就没有机会再 fetchlinks 了
所以不应该 exit 而应该继续循环
你每次 fetchlinks 到的 url 被存放于 $urlarray 并没有参与后续的查找
所以至多是 $url 遍历结束就结束了。这样取到的是 $url 中可能存在的所有一级连接
看你的需求,似乎应该循着获取的连接一直深入下去的
假定 $netbot->results 是一个关于连接的一维数组,name
for($i=0; $i
if ($netbot->fetchlinks($val)){ //如果有链接 $url = array_merge($url, $netbot->results); //就将连接加入搜寻队列 }}
是不是搞错了break和exit?
楼主放弃了吗?
应该在if的第一个条件再循环

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
