1、file_get_contents获取文本或者网页的内容
$filename [, bool $use_include_path = false [, resource $context [, int $offset = -1 [, int $maxlen ]]]] )
2、file_get_contents把内容写入到文件
$filename , mixed $data [, int $flags = 0 [, resource $context ]] )$filename , string $mode [, bool $use_include_path = false [, resource $context ]] )$handle , int $length )fwrite — 写入文件(可安全用于二进制文件)
$handle , string $string [, int $length ] )fclose — 关闭一个已打开的文件指针
$handle )fgets — 从文件指针中读取一行
