嗨,我必须检查URL是否被找到。如果URL可用,我需要在iframe
中加载URL
。我们如何做到这一点?
我的示例代码
<?php
$url = 'http://example.com/t/urlname';
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, TRUE);
/* Get the HTML or whatever is linked in $url. */
$response = curl_exec($handle);
/* Check for 404 (file not found). */
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
if($httpCode == 404) {
/* Handle 404 here. */
echo "Url Not found";
} else { ?>
<div id="iframe-comments">
<iframe src="<?php echo $url; ?>" scrolling="no" style="width: 800px; height: 800px;">
</iframe>
</div>
<?php
}
curl_close($handle);
?>
在这种情况下,如果URL是可用的,它不加载/显示iframe
Div
。请建议更好的选项加载iframe
试试下面的代码:
不使用cURL
也可以做同样的事情$url = 'http://thedemon.in';
$file_headers = @get_headers($url);
if($file_headers[0] == 'HTTP/1.1 200 OK') {
?>
<div id="iframe-comments">
<iframe src="<?php echo $url; ?>" scrolling="no" style="width: 300px; height: 300px;"> </iframe>
</div>
<?php
}
else {
echo "Url Not found";
}
