我一直在使用下面的代码来获取网页的html内容PHP文件\u获取\u内容无法获取html代码,php,html,Php,Html,我一直在使用下面的代码来获取网页的html内容 $url = "http://mysmallwebpage.com/"; $html = file_get_contents($url); 但是，file\u get\u contents无法以以下形式打开URL，但是如果我在web浏览器的地址栏中键入它们，这些URL可以正常打开 www.etsy.com/listing/118415624/not-my-small-diary-17-true-high-school blog.al.com/bi

$url = "www.etsy.com/listing/118415624/not-my-small-diary-17-true-high-school";
$html = file_get_contents($url);
除非您没有使用http://PHP作为前缀，否则您不会知道您想要一个网页，并尝试在文件系统上：
$url = "http://www.etsy.com/listing/118415624/not-my-small-diary-17-true-high-school";
$html = file_get_contents($url);
if (FALSE === $html) {
throw new Exception(sprintf('Failed to open HTTP URL "%s".', $url));

使用http://before www.etsy.com/listing/118415624/not-my-small-diary-17-true-high-school试试这个，效果很好
$url = "http://www.etsy.com/listing/118415624/not-my-small-diary-17-true-high-school";
$html = file_get_contents($url);
echo "<pre>";
print_r($html);
exit;
在url中使用http。在php中选中allow\u url\u fopen。此外，函数在失败时返回读取数据或FALSE。他们还应该检查返回值是否为FALSEYes，验证函数返回值的一般规则对于使用文件\u get\u内容进行错误检查至关重要。将突出这一点，好观点@HankyPankyㇱ!
