读取文件 URL路由内容到字符串

1 file_get_condents();一般做读取文件内容使用     大文件时可做分段读取

$content=file_get_contents("2.sql",FALSE,NULL,1024*1024,1024);

2  file_put_contents();存入文件内容,未搜索到文件则创建新文件 

   FILE_APPEND追加至文件末尾  

   PHP_EOL 换行符

file_put_contents('./runtime/toxml.txt', var_export($data,true).PHP_EOL,FILE_APPEND);

3 关于CURL用法  https://www.cnblogs.com/ldj3/p/9296071.html

封装方法:
/**
* CURL请求
* @param $url 请求url地址
* @param $method 请求方法 get post
* @param null $postfields post数据数组
* @param array $headers 请求header信息
* @param bool|false $debug 调试开启 默认false
* @return mixed
*/

{
$method = strtoupper($method);
$ci = curl_init();
