Question

当我使用此功能function get_data($url)时，我的所有内容网站都会消失，我尝试使用function get_web_page( $url )，但无效...

使用此功能，我希望在另一个网站上看到来自http://swapes.com/version.txt的内容..

如果function get_data($url)无效，可以使用什么？

function get_data($url)
{
    $ch = curl_init();
    $header = array(
                "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*\/*;q=0.5",
                "Accept-Language: en-us,en;q=0.5",
                "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7",
                "Cache-Control: max-age=0",
                "Connection: keep-alive",
                "Keep-Alive: 300",
                "Pragma: ");
    $timeout = 30;
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_HTTPHEADER, $header); 
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_FORBID_REUSE,1); 
    curl_setopt($ch,CURLOPT_FRESH_CONNECT,1); 
    curl_setopt($ch,CURLOPT_IPRESOLVE,CURL_IPRESOLVE_V4); 
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    if(!empty($data)){
        return $data;
    }elseif(function_exists('file_get_contents')){
        return file_get_contents($url);
    }else{
        return '';
    }
}

    // Get Latest Version
    include_once("../version.php");
    $l_version = get_data('http://swapes.com/version.txt');

这是来自footer.php的代码php，当我添加＆＃34; get_data＆＃34;代码消失了页脚。

 <?
include_once("test1.php");

?>

您需要添加echo语句来打印您的函数返回的数据。

// Get Latest Version
include_once("../version.php");
echo $l_version = get_data('http://swapes.com/version.txt'); //<--- Add `echo` as shown.

修改后的代码

<?php

function get_data($url)
{
    $ch = curl_init();
    $header = array(
        "Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*\/*;q=0.5",
        "Accept-Language: en-us,en;q=0.5",
        "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7",
        "Cache-Control: max-age=0",
        "Connection: keep-alive",
        "Keep-Alive: 300",
        "Pragma: ");
    $timeout = 30;
    curl_setopt($ch,CURLOPT_URL,$url);
    curl_setopt($ch,CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_FORBID_REUSE,1);
    curl_setopt($ch,CURLOPT_FRESH_CONNECT,1);
    curl_setopt($ch,CURLOPT_IPRESOLVE,CURL_IPRESOLVE_V4);
    curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    if(!empty($data)){
        return $data;
    }elseif(function_exists('file_get_contents')){
        return file_get_contents($url);
    }else{
        return '';
    }
}

// Get Latest Version
include_once("../version.php");
echo $l_version = get_data('http://swapes.com/version.txt');

使用函数从url .txt获取数据
