由于技术不够,整天在逛论坛。 看到许多关于抓取网页内容(file_get_contents)和抓取url(这个不知道用什么)对这个听感兴趣。望大神指点下这是怎么回事?最好能帮我整个源码嘎嘎。叫我参考下。
回复讨论(解决方案)
自己百度先吧
我用 php socket 和 curl写过真实的例子,至于 file_get_contents更简单了,原理都一样,你看以看看
不足之处请指点,

curl
手册里有例子,必须要看手册阿
百度一下,可以找到很多的。
百度 php 采集
baidu下 file_get_contents()和curl 抓取采集
$url='http://www.iheima.com/';
$con=file_get_contents($url);
if ($con){
preg_match_all('/
(.+).*(.+)/isU', $con, $temp,PREG_SET_ORDER);
foreach ($temp as $key=> $v){
$title=$v[2];
$v_url=$v[1];
$des=$v[3];
$con_url=file_get_contents($v_url);
if ($con_url){
$tags='';
preg_match('/keywords" content="(.+)"/isU', $con_url,$tags);
$tags=trim($tags[1],',');
preg_match('/class="txs_Content".*>(.+)/isU', $con_url,$txt);
$txt=$txt[1];
}
}
} 够清楚了吧
有个开源的simple_html_dom
$html = file_get_html('http://www.baidu.com');
可以根据各种抓取,如id,css等方法抓取网页内容
foreach ($temp as $key=> $v){
$title=$v[2];
$v_url=$v[1];

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
