提取并显示从 PHP 中的文本文件中分隔的所有 10 位数字逗号

Question

我正在寻找一种从包含字母、数字和特殊字符的文本文件中提取所有 10 位数字逗号分隔的方法。

我现在能做的是使用这个代码：

$texts  = "cache/en.txt";
$contents = file_get_contents($texts);
$showtexts = explode(',', $contents);
$showtextsclean = preg_replace('/\d{10}/', '', $showtexts);

foreach($showtextsclean as $final) {
    echo $final;
}

上面的代码的作用是相反的，它显示除 10 位数字之外的所有内容。我真正想要的是提取所有 10 位数字并将逗号与示例分开：

{"left-right-kato":1566025480,"ladies-night-sys-bjerre":1563248008,"catch-fire-bj-rnskov":1563179104,"jeg-dr-mte-om-en-r-d-lavth-ngende-sol-rasmus-walter":1562991777,"45-fahrenheit-girl-the-remixes-drew-sycamore":"not found","bebe-zk":1469386794,"ahora-rozenberg":1566345117,"precious-leave-me-on-the-floor-liss":1560827606}

这样我就可以这样呼应了：

1566025480,1563248008,1563179104,1562991777,1469386794,1566345117,1560827606

Answer 1

<?php
$showtextsclean = '{"left-right-kato":1566025480,"ladies-night-sys-bjerre":1563248008,"catch-fire-bj-rnskov":1563179104,"jeg-dr-mte-om-en-r-d-lavth-ngende-sol-rasmus-walter":1562991777,"45-fahrenheit-girl-the-remixes-drew-sycamore":"not found","bebe-zk":1469386794,"ahora-rozenberg":1566345117,"precious-leave-me-on-the-floor-liss":1560827606}';

$digig10 = '/\b(\d{10})\b/';
preg_match_all($digig10,$showtextsclean,$match);
print_r($match[1]);
?>

它取代了所有不是大于或小于 10 位的数字

并从末尾修剪逗号并开始

给出这个结果：

Array
(
    [0] => 1566025480
    [1] => 1563248008
    [2] => 1563179104
    [3] => 1562991777
    [4] => 1469386794
    [5] => 1566345117
    [6] => 1560827606
)
