在PHP控制台中读取空格分隔的整数

你可以用 fscanf(STDIN, "%d %d %d\n", $a, $b, $c);

例子:

<?php
$stdin = fopen('php://stdin', 'r');

print_r("Your 3 numbers:\n");

fscanf($stdin, "%d %d %d\n", $a, $b, $c);

print_r(sprintf('$a : %d $b : %d $c : %d' . "\n", $a, $b, $c));

如果您需要有关格式化字符串的更多信息,您可能需要查看 php documentation for sprintf

fscanf . 那么 fscanf公司 返回包含所有解析值的数组。

<?php
$stdin = fopen('php://stdin', 'r');

print_r("How many numbers do you want to enter? :  ");
fscanf($stdin, "%d\n", $n);    

print_r("Your ". $n . " numbers:\n");

$result = fscanf($stdin, str_repeat("%d ", $n). "\n");

print_r("I have parsed " . implode($result, ", ") . "\n");

输出如下所示:

How many numbers do you want to enter? :  10
Your 10 numbers:
1 1 2 3 5 8 13 21 34 55
I have parsed 1, 1, 2, 3, 5, 8, 13, 21, 34, 55
