PHP在最后一个数字处分割字符串，插入一个额外的字符串并合并新的字符串 [英] PHP split string at last number, insert an extra string and merge the new string
本文介绍了PHP在最后一个数字处分割字符串，插入一个额外的字符串并合并新的字符串的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我构建了一个计算脚本，该脚本需要几秒钟的时间，并在包含标签等的y:d:h:m:s中显示它们.
I have build a calculating script that takes seconds and show them in y:d:h:m:s containing labels etc.
例如 15768012 = 1年12秒和 27362 = 15小时6分2秒.
脚本运行良好，但是我想查看字符串并用最后一个数字(而不是第一个数字)分割，然后插入单词 and ，以便:
The script works perfectly, but I would like to look in the string and split it by the last number (not the first) and then insert the word and so that:
15768012 = 1年12秒钟和 27362 = 15小时6分钟2秒.
如果需要，我可以编写我的脚本，但是我认为它不会帮助您解决此问题.
I can write my script if you need it, but I don't think it will help you solve this question..
让我们说 $ string = '15小时6分2秒'您将如何拆分它并导入文本 and ?
let's say that $string = '15 hours 6 minutes 2 seconds' how would you split it and import the text and ?

感谢大家的帮助..这是简化的脚本..但是，我遇到了一个新问题..当您在字段中键入小于 1576 时，它会写一些与我想要...
Thanks everybody for your help.. here is the simplified and done script.. I have a new problem though.. when you type less than 1576 in the field, it writes some different numbers than I want it to...
问题现已解决.欢迎使用脚本:D
Problem now fixed.. Welcome to use the script :D

推荐答案
一个快速修复方法可能是:
A quick fix may be:
$string = '15 hours 6 minutes 2 seconds';
$pattern ='/ \d+ \w+$/';
$string = preg_replace($pattern, ' and$0', $string);
但是，您可能需要研究一个更好的解决方案，该解决方案可以构建以下数组:
However, you may want to look into a nicer solution which resulted in the following array being built:
$time = array($a, $b, $c, $e, $q);
然后您可以这样做:
$time = array_filter($time);
$last = array_pop($time);
$string = implode(', ', $time) . ' and ' . $last;
