文本爆炸和循环 PHP 结果是错误的

Question

文本爆炸和循环php结果是错误的但我尝试将此文本结果为 1 到 50 行但结果更重复

<?php
$text   = "1*10 11*20 21*30 31*40 41*50";
$textAr = explode("n", str_replace("r", "", $text));
$textAr = array_filter($textAr, 'trim');
foreach ($textAr as $line) {
    $pieces = explode("*", $line);
    list($first, $last) = array_pad(explode('*', $line, 2), 2, null);
    $add = 1;
    for ($i = $first; $i <= $last; $i += $add) {
        $array[] = array(
            'count' => $i
        );
    }
    $codes = $array;
    foreach ($codes as $code) {
        echo $code['count'];
        echo "<br>";
    }
}
?>

结果 ： 150 行

1,2,3,4,5,6,7,8,9,10,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,1,2,3,4,5,6,7,8,9,10,11,12,1 3,14,15,16,17,18,19,20,21,22,23,24,25,26 ，27,28,29,30,1,2,3,4 5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 ，20,21,22,23,24,25,2 6,27,28,29,30,31,32,33,34,35,36,37,38,39,40,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 ，23,24,25,26,27,28,2 9,30,31,32,33,34,35,36,37,38,39,40,41,42 ，

但我想要

结果，但我想要没有重复的结果 1-50

您只需要将打印件移到 foreach 循环之外即可。此代码会将数字从 1 到 10、11 到 20 相加。等，根据输入[这是$text]。并在最后打印所有这些。

<?php
$text   = "1*10
11*20
21*30
31*40
41*50";
$textAr = explode("n", str_replace("r", "", $text));
$textAr = array_filter($textAr, 'trim');
foreach ($textAr as $line) {
    $pieces = explode("*", $line);
    list($first, $last) = array_pad(explode('*', $line, 2), 2, null);
    $add = 1;
    for ($i = $first; $i <= $last; $i += $add) {
        $array[] = array(
            'count' => $i
        );
    }

}
$codes = $array;
foreach ($codes as $code) {
    echo $code['count'];
    echo "<br>";
}
?>

结果：

1 2
3 4

5
6
7 8
9

10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31
