php中如何将多维数组转换为单个数组?我花了几个小时来寻找解决方案,但找不到适合我的解决方案。这是我的代码:
<?php
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
"http" => array(
"header" => "User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36"
)
)
);
$source_url = 'http://netsparker.com/';
$html = file_get_contents($source_url,false, stream_context_create($arrContextOptions));
$dom = new DOMDocument;
@$dom->loadHTML($html);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
$result_url = $link->getAttribute('href');
if (!preg_match('/^https?:\/\//', $result_url)) {
$result_url = $source_url . preg_replace('/^\//', '', $result_url);
}
$array2 = array($result_url);
print_r($array2);
}
?>
Array
(
[0] => http://github.com/#start-of-content
)
Array
(
[0] => https://help.github.com/articles/supported-browsers
)
Array
(
[0] => https://github.com/
)
Array
(
[0] => http://github.com/join?ref_cta=Sign+up&ref_loc=header+logged+out&ref_page=%2F&source=header-home
)
Array
(
[0] => http://github.com/features
)
Array
(
[0] => http://github.com/features/code-review/
)
Array
(
[0] => http://github.com/features/project-management/
)
....
我想把它变成:
Array
(
[0] => http://github.com/
[1] => http://github.com/collections
[2] => http://github.com/topics
[3] => http://github.com/explore
[4] => http://github.com/enterprise
.......
)
我尝试使用 foreach、ArrayIterator、flatten 但似乎不起作用。我还尝试将 result_url 转换为数组,但也不起作用。
