如何生成字母增量字符串？

Question

例如 我正在寻找一个不断递增字母的功能 以“aaaaaa”开头并前往“aaaaab”并以“zzzzzz”结尾

Answer 1

使用PHP的increment characters Perl style

功能

$char = 'aaaaaa';
$endChar = 'zzzzzz';
$endChar++;
while ($char != $endChar) {
    echo $char++, PHP_EOL;
}

Answer 2

只需使用增量运算符

$start = "aaaaaa";
$end = "zzzzzz";

while($start ++ != $end) {
    // print after every 10,000,000 million
    (@$i ++ % 10000000 == 0) and print($start . PHP_EOL);
}

echo "Total  ", number_format($i, 0);

输出

aaaaab
avwyxl
brtxuv
cnqwsf
djnvpp
efkumz
fbhtkj
fxesht
gtbrfd
hoyqcn
ikvozx
