fwrite和variable=fwrite的区别

Question

$name="Jimmy";
$open = fopen("first.txt","w");
$write = fwrite($open,$name);

这和它有什么区别？

$name="Jimmy";
$open = fopen("first.txt","w");
fwrite($open,$name);

变量$write做了什么？我们为什么要使用它？

来自文档：http://php.net/manual/en/function.fwrite.php

int fwrite (资源$handle，字符串$string，int $length )

您的变量$write将具有: fwrite()返回写入的字节数，如果出错则返回FALSE。
