文本爆炸和循环php结果是错误的但我尝试这个文本结果1至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

但我想要结果，但我想要结果1-50没有重复

Answer 1

您只需将打印件移到foreach循环外部即可。此代码将根据输入[即$ text]添加1到10,11到20等的数字。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：
