从表单中解析多个 url
我正在尝试制作一个脚本,该脚本在表单中给出的网址列表中搜索电子邮件地址。有人可以建议我该怎么做吗?有 cURL 的替代方案吗? 我尝试使用 file_get_contents 来实现,但脚本仅分析表单中给出的最后一个 url:例如,当我在表单中输入两个 url 时,第一个“print_r("show current_url:". $current_url); 为空并且第二个它显示页面(url)内容(没有图片)。
您的帮助。
我在不同的论坛上询问,但没有收到答案,非常感谢
$urls = explode("\n", $_POST['urls']);
$db = new mysqli('localhost', 'root', 'root', 'urls');
if (mysqli_connect_errno()) {
echo 'Błąd: ';
exit;
}
for ($i=0; $i<count($urls); $i++){
print_r("show link:". $urls[$i]."<br>");
$current_url = file_get_contents($urls[$i]);
print_r("show current_url:". $current_url);
preg_match( "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $current_url, $email);//email
print_r ("show email:".$email[0]);
$query = "INSERT INTO urle set adres = '$email[0]' ";
$result = $db->query($query);
}
if ($query) {
echo $db->affected_rows ."pozycji dodano.";
} else {
echo mysql_errno() . ":" . mysql_error() . "Wystąpił błąd przy dodawaniu urli ";
}
$db->close();
?>
编辑: 我尝试过使用curl。 var_dump($电子邮件);显示:数组(0) { } 现在,该脚本会在浏览器中显示表单中给出的所有 url,但 preg_match 不起作用,因此它不会提取电子邮件地址。
<?php
$urls = explode("\n", $_POST['urls']);
$db = new mysqli('localhost', 'root', 'root', 'linki');
if (mysqli_connect_errno()) {
echo 'Błąd: ';
exit;
}
for ($i=0; $i<count($urls); $i++){
$url = $urls[$i];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
$output = curl_exec($ch);
preg_match( "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $output, $email);//email
var_dump($email);
$query = "INSERT INTO urle set adres = '$email[0]' ";
$result = $db->query($query);
curl_close($ch);
}//
if ($result) {
echo $db->affected_rows ."pozycji dodano.";
} else {
echo mysql_errno() . ":" . mysql_error() . "Wystąpił błąd przy dodawaniu urli ";
}
$db->close();
?>
I'm trying to make a script, which search the list of urls given in the form for the email adresses. Could anyone advice me how to do it? Is there some alternative to cURL?
I tried to make it with file_get_contents, but the script analyze only the last url given in the form: when I enter for example two urls to the form, the first "print_r("show current_url:". $current_url); is empty and for the second it shows the page(url) content(without pictures).
I asked on different forums, but received no answer. Will really appraciate your help.
Thank you
$urls = explode("\n", $_POST['urls']);
$db = new mysqli('localhost', 'root', 'root', 'urls');

print_r("show link:". $urls[$i]."<br>");
$current_url = file_get_contents($urls[$i]);
print_r("show current_url:". $current_url);
preg_match( "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $current_url, $email);//email
print_r ("show email:".$email[0]);
$query = "INSERT INTO urle set adres = '$email[0]' ";
$result = $db->query($query);
}
if ($query) {
echo $db->affected_rows ."pozycji dodano.";
} else {
echo mysql_errno() . ":" . mysql_error() . "Wystąpił błąd przy dodawaniu urli ";
}
$db->close();
?>
EDIT:
I have tried with curl. var_dump($email); shows: array(0) { }
The script displays now all of the urls given in the form in the browser, but preg_match doesn't work, so it doesn't extract email adresses.
<?php
$urls = explode("\n", $_POST['urls']);
$db = new mysqli('localhost', 'root', 'root', 'linki');
if (mysqli_connect_errno()) {
echo 'Błąd: ';
exit;
}
for ($i=0; $i<count($urls); $i++){
$url = $urls[$i];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
$output = curl_exec($ch);
preg_match( "/[\._a-zA-Z0-9-]+@[\._a-zA-Z0-9-]+/i", $output, $email);//email
var_dump($email);
$query = "INSERT INTO urle set adres = '$email[0]' ";
$result = $db->query($query);
curl_close($ch);
}//
if ($result) {
echo $db->affected_rows ."pozycji dodano.";
} else {
echo mysql_errno() . ":" . mysql_error() . "Wystąpił błąd przy dodawaniu urli ";
}
$db->close();
?>

file_get_contents
,它不会给您任何错误消息(除非引发 error_reporting),除非设置了ini_set("user_agent", ...)
,否则通常会被阻止。或者,在较新的 PHP 安装上使用
HttpRequest
。不过
curl
使用起来并不困难。该手册充满了示例。没有人能告诉你。调试它是你的责任(特别是因为你没有在问题中提到受影响的url)。使用curl或httprequest。
file_get_contents
, which doesn't give you any error messages (unless error_reporting is raised), and which is often blocked unlessini_set("user_agent", ...)
was set.Alternatively
HttpRequest
on newer PHP installations.Still
curl
is not difficult to use. The manual is full of examples.Nobody can tell. It's your duty to debug that (especially since you haven't mentioned the affected url in your question). Use curl or httprequest.
好的,我已经修好了!:)
这是代码:
Ok, i've fixed it!!!:)
Here is the code:
