Array problem.

The code is as follows

foreach ($url as $val) {if ($netbot->fetchlinks ($val)) {$urlarray [] = $netbot->results;} Else{echo "Error:". $netbot->error;exit;}}

This is an array, storing the address
Through the Snoopy method, $netbot->fetchlinks ($val) to get all the link for this URL
So, I want to put all the link in an array

$netbot->results Returns a one-dimensional array

The question now is: $urlarray [] = $netbot->results;

This method assigns a value that gets a multidimensional array

The link in it is only the first time he visited the URL links



I want this $urlarray to be transferred automatically.
When you get the second URL, when you assign a value, you can inherit the subscript above, transforming $urlarray into a 1-dimensional array.

How can this be achieved?

The IF condition inside again cycle?

foreach ($netbot->results as $v) {
$urlarray [] = $v;
}

First, whatever $netbot->results got.
You exit after $netbot->fetchlinks ($val) failed.
Then there's no chance of any further fetchlinks in the $url $val.
So should not exit and should continue to circulate

Every time you fetchlinks to the URL is stored in the $urlarray and does not participate in subsequent lookups
So at the very end of the $url traversal is over. This takes all the first-level connections that may exist in the $url

Look at your needs, it seems that you should follow the access to the connection has been deep down

Suppose $netbot->results is a one-dimensional array of connections, name
for ($i =0; $i

  if ($netbot->fetchlinks ($val)) {//If there is a link    $url = array_merge ($url, $netbot->results);//Add the connection to the search queue  }}

Did you get the wrong break and exit?

Did the landlord give up?
It should be recycled in the first condition of the IF
