php - 如何使用 fscanf 读取整行(字符串)？

Question

我有一个文本文件，我正在逐行阅读。当我到达字符串(六个字长)那一行时，我想读取它并将其分配给变量 $str，所以我这样做:

fscanf($handle, "%s", $str);

//The line is "one two three four"

echo $str ; // prints out "one"

但是，由于每个单词后面都有空格，它只保存字符串的第一个单词。我如何捕捉整个事物？

这是一个老问题，但对于 googlers:

To read a whole line with fscanf(), use "%[^\n]". In fscanf(), $[^characters] means to match any sequence of characters that isn't in the set between the brackes (it's similar to [^characters]* in a regular expression). So this matches any sequence of characters other than newline. See http://php.net/manual/en/function.sscanf.php#56076
