如何获取HTML文件作为PHP var中的字符串，可以通过它运行正则表达式？

How can I get the HTML file as a string in a PHP var so that I can run a regular expression through it?

Curl不工作，因为它忽略了错误的部分。

simple_html_dom .php 有相同的问题。

wget 不工作，因为我没有权限在

Curl doesn't work as it is ignoring the bad part.
simple_html_dom.php has the same issue.
wget doesn't work since I don't have permissions for it on the server.

推荐答案

file_get_contents - 将整个文件读入字符串

file_get_contents — Reads entire file into a string

string file_get_contents ( 
    string $filename [, int $flags= 0 [, resource $context [, int $offset= -1 [, int $maxlen= -1 ]]]] 
)

：

此函数与file（）类似，除了file_get_contents （）返回一个字符串中的文件，从指定的偏移量开始到maxlen个字节。失败时，file_get_contents（）将返回FALSE。

This function is similar to file(), except that file_get_contents() returns the file in a string, starting at the specified offset up to maxlen bytes. On failure, file_get_contents() will return FALSE.

file_get_contents（）是将文件内容读入字符串的首选方法。

file_get_contents() is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by your OS to enhance performance.

它可以与网页和文件一起使用。您可以抓取HTML，只需使用 http://whatever.com/page.html 作为$ filename。

And it works both with webpages and files. You can grab the HTML, just by using "http://whatever.com/page.html" as $filename.
