添加一个值字母数字

Question

我实现了获取字母数字值和加一值的功能。

$string = "VDLE009567";
$person = $numbers = array();

if(preg_match_all('/([a-z ]+[0-9]+)/i', $string, $mt)) {
 $nrmt = count($mt[0]);
 for($i=0; $i<$nrmt; $i++) {
   if(preg_match('/([a-z ]+)([0-9]+)/i', $mt[0][$i], $mt2)) {
     echo $person[$i] = trim($mt2[1]);
     echo $numbers[$i] = $mt2[2];
 }
 }
}
echo $numbers=$numbers[0]+1;

我需要获得 "VDLE009568" 的值，但我得到了 "VDLE9568" 的值。有什么办法可以得到这个 "VDLE009568"

将此代码用于结果

<?php
$string = "VDLE999999";
$person = $numbers = array();

if (preg_match_all('/([a-z ]+[0-9]+)/i', $string, $mt)) {
    $nrmt = count($mt[0]);
    for ($i = 0; $i < $nrmt; $i++) {
        if (preg_match('/([a-z ]+)([0-9]+)/i', $mt[0][$i], $mt2)) {
            $personout   = $person[$i] = trim($mt2[1]);
            $numbers[$i] = $mt2[2];
            if ($numbers[0] == 999999) {
                $last      = substr($personout, -1, 1);
                $personout = substr($personout, 0, -1) . (++$last);
                $numbers[0] = 0;
            }
            echo $personout;
        }
    }
}
echo $numbers = str_pad($numbers[0] + 1, 6, '0', STR_PAD_LEFT);

根据您的要求，我对代码进行了一些更改

<?php

$string = "VDLE999999";
$person = $numbers = array();
if(preg_match_all('/([a-z ]+[0-9]+)/i', $string, $mt)) {
  $nrmt = count($mt[0]);
 for($i=0; $i<$nrmt; $i++) {
   if(preg_match('/([a-z ]+)([0-9]+)/i', $mt[0][$i], $mt2)) {
      $person[$i] = trim($mt2[1]);
      $numbers[$i] = $mt2[2];
 }
  }
}
  $num = (string)$numbers[0];
  $word_length = strlen($num);
  $max = 9;
  $max_str = '';
  for($i=0;$i<$word_length;$i++){
      $max_str .=$max; 
  }
  $max_str = (int)$max_str;
  if($num < $max_str){
      echo $numbers=str_pad($num+1, $word_length, '0', STR_PAD_LEFT);
  }else{
        $numbers=str_pad($num+1,$word_length+1, '0', STR_PAD_LEFT);
        $new_str = strrev((string)$numbers);
        $new_num = (int)$new_str;
        echo $numbers = str_pad($new_num,$word_length+1, '0', STR_PAD_LEFT);
  }
