In PHP, the file_get_contents function captures the https address (two methods)

This article uses two methods to solve the problem that the file_get_contents function in PHP fails to capture the https address. if you need it, refer to Method 1 below:

In php, when an https website is crawled, the following error message is displayed:

Warning: file_get_contents () [function. file-get-contents]: failed to open stream: Invalid argument in I: Webmyphpa. php on line 16

Open the php. ini file and find; extension = php_openssl.dll, remove double quotation marks ";". restart the web server.

If the apache server is used, the mod_ssl module test can be enabled at the same time.

If it is not convenient to modify the server configuration, you can use the following functions to solve the problem:

Sample code:

<? Php // file_get_contents captures the https address content function getCurl ($ url) {$ ch = curl_init (); curl_setopt ($ ch, CURLOPT_URL, $ url); curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt ($ ch, CURLOPT_SSL_VERIFYHOST, false); $ result = curl_exec ($ ch); curl_close ($ ch ); return $ result ;}

Method 2:

In php, when the file_get_contents function is used to capture the website content starting with https, an error warning similar to the following occurs:

Warning: file_get_contents (https: // 127.0.0.1/index. php) [function. file-get-contents]: failed to open stream: Invalid argument in E: \ website \ blog \ test. php on line 25

Open php. ini and find; extension = php_openssl.dll, remove double quotation marks ";". restart the web server.
