php file_put_contents()功能函数(集成了fopen、fwrite、fclose)

Jun 13, 2016 pm 12:09 PM
fclose fi file fopen fwrite php put function Function Order

命令:file_put_contents();
命令解析:file_put_contents (PHP 5)
file_put_contents -- 将一个字符串写入文件
说明:
int file_put_contents ( string filename, string data [, int flags [, resource context]] )

和依次调用 fopen(),fwrite() 以及 fclose() 功能一样。
参数 data 可以是数组(但不能为多维数组),这就相当于 file_put_contents($filename, join('', $array))
自 PHP 5.1.0 起,data 参数也可以被指定为 stream 资源,这里 stream 中所保存的缓存数据将被写入到指定文件中,这种用法就相似于使用 stream_copy_to_stream() 函数。
参数

filename
要被写入数据的文件名。
data
要写入的数据。类型可以是 string,array 或者是 stream 资源(如上面所说的那样)。
flags
flags 可以是 FILE_USE_INCLUDE_PATH,FILE_APPEND 和/或 LOCK_EX(获得一个独占锁定),然而使用 FILE_USE_INCLUDE_PATH 时要特别谨慎。
context
一个 context 资源。
写入代码(代码本身无错,但阴差阳错学会了它的另一个功能):

复制代码 代码如下:


$contents = "这是使用file_put_contents写入的内容";
$contents2 = array("这是使用","file_put_contents","命令写入的内容");
file_put_contents("html/caceh.txt",$contents);
file_put_contents("html/cache2.txt",$contents2);
?>


代码分析:打算使用file_put_contents命令向cache.txt,cache2.txt这两个文件中写入字符串。
结果:在html文件目录内新增了caceh.txt文件,你懂了吧————
谨记:file_put_contents()函数集成了fopen(),fwrite(),fclose()三种函数,此例中新建的文件就是fopen()的功能.
