怎么用php读取并显示另一个php文件的内容？
示例代码1: 用file_get_contents以GET方式获取内容
<?php
$url = '';
$html = file_get_contents($url);
// print_r($http_response_header);
echo $html;
printhr();
printarr($http_response_header);
printhr();
?>
示例代码2: 用fopen打开URL，以GET方式获取内容
<?php
$fp = fopen($url, 'r');
printarr(stream_get_meta_data($fp));
printhr();
while (!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url body: $result";
printhr();
fclose($fp);
?>
示例代码3：用file_get_contents函数，以POST方式获取URL
<?php
$data = array('foo' => 'bar');
$data = http_build_query($data);
$opts = array(
'http' => array(
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
"Content-Length: " . strlen($data) . "\r\n",
'content' => $data
),
);
$context = stream_context_create($opts);
$html = file_get_contents('', false, $context);
echo $html;
?>
示例代码4：用fsockopen函数打开URL，以GET方式获取完整的数据，包括header和body
<?php
function get_url($url, $cookie = false) {
$url = parse_url($url);
$query = $url['path'] . "?" . $url['query'];
echo "Query:" . $query;
$fp = fsockopen($url['host'], $url['port'] ? $url['port'] : 80, $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = "GET $query HTTP/1.1\r\n";
$request .= "Host: $url[host]\r\n";
$request .= "Connection: Close\r\n";
if ($cookie) $request .= "Cookie: $cookie\r\n";
$request .= "\r\n";
fwrite($fp, $request);
while (!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
// 获取URL的HTML部分，去掉header
function GetUrlHTML($url, $cookie = false) {
$rowdata = get_url($url, $cookie);
if ($rowdata) {
$body = stristr($rowdata, "\r\n\r\n");
$body = substr($body, 4, strlen($body));
return $body;
}
return false;
}
?>
示例代码5：用fsockopen函数打开URL，以POST方式获取完整的数据，包括header和body
<?php
function HTTP_Post($URL, $data, $cookie, $referrer = "") {
// parsing the given URL
$URL_Info = parse_url($URL);
// Building referrer
if ($referrer == "") // if not given use this script as referrer
$referrer = "111";
// making string from $data
foreach ($data as $key => $value)
$values[] = "$key=" . urlencode($value);
$data_string = implode("&", $values);
// Find out which port is needed - if not given use standard (=80)
if (!isset($URL_Info["port"]))
$URL_Info["port"] = 80;
// building POST-request:
$request = "POST " . $URL_Info["path"] . " HTTP/1.1\n";
$request .= "Host: " . $URL_Info["host"] . "\n";
$request .= "Referer: $referrer\n";
$request .= "Content-type: application/x-www-form-urlencoded\n";
$request .= "Content-length: " . strlen($data_string) . "\n";
$request .= "Connection: close\n";
$request .= "Cookie: $cookie\n";
$request .= "\n";
$request .= $data_string . "\n";
$fp = fsockopen($URL_Info["host"], $URL_Info["port"]);
fputs($fp, $request);
while (!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
return $result;
}
printhr();
?>
示例代码6: 使用cURL库
<?php
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, '');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
关于cURL库：
cURL 官方网站
cURL 是使用 URL 语法的传送文件工具，支持 FTP、FTPS、HTTP、HTTPS、SCP、SFTP、TFTP、TELNET、DICT、FILE 和 LDAP。cURL 支持 SSL 证书、HTTP POST、HTTP PUT、FTP 上传、Kerberos、基于 HTTP 格式的上传、代理、Cookie、用户+口令验证、文件传送恢复、HTTP 代理通道等实用功能。
<?php
function printarr(array $arr) {
echo "<br> Row field count: " . count($arr) . "<br>";
foreach ($arr as $key => $value) {
echo "$key = $value <br>";
}
}
?>
一个php文件读取调用另一个
使用 include 方法载入配置文件。
1.php 的代码如下：
<?php
$config = include __DIR__ . '/2.php';
var_dump($config);
2.php 的代码如下：
<?php
$config['mydbhost'] = 'localhost';
$config['mydbuser'] = 'root';
$config['mydbpwd'] = 'root';
$config['mydbname'] = '80cms1';
$config['mydbcharset'] = 'utf8';
return $config;
php读取文件夹并输出？
<?php
$dir = "./images/"; // 要获取的目录
echo "********** 获取目录下所有文件和文件夹 ***********<hr/>";
// 先判断指定的路径是不是一个文件夹
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) != false) {
// 文件名的全路径 包含文件名
$filePath = $dir . $file;
echo "<img src='" . $filePath . "'/>";
}
closedir($dh);
}
}
?>
php读取文件并输出
直接 echo 就可以了……
echo file_get_contents($requestUrl);
（各种错误处理啥的您自己看着办吧）
PHP中读取文件的几个方法
// 方法一
file_get_contents();
// 方法二
$path = './hello.txt';
$mode = 'a';
$file = fopen($path, $mode);
