PHP在最后一个数字处拆分字符串，插入一个额外的字符串并合并新字符串

I have build a calculating script that takes seconds and show them in y:d:h:m:s containing labels etc.

eg. 15768012 = 1 year 12 seconds and 27362 = 15 hours 6 minutes 2 seconds.

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 year AND 12 seconds and 27362 = 15 hours 6 minutes AND 2 seconds.

I can write my script if you need it, but I don't think it will help you solve this question..

let's say that $string = '15 hours 6 minutes 2 seconds' how would you split it and import the text and ?

<?
if (isset($_POST['number'])) {
    $x = $_POST['number'];
} else {
    $x = 54098;
}

// Labels
$lb_y = 'year';
$lb_ys = 'years';
$lb_d = 'day';
$lb_ds = 'days';
$lb_h = 'hour';
$lb_hs = 'hours';
$lb_m = 'minute';
$lb_ms = 'minutes';
$lb_s = 'second';
$lb_ss = 'seconds';
$lb_and = 'and';

//$x = 54098; // Time in seconds - change to $row['time'];

$f = 15768000; // seconds in a year
$d = 43200; // seconds in a day
$t = 3600; // seconds in an hour
$m = 60; // senconds in a minute


// Let's check if it is more than a minute
if ($x >= $m) {

    // More than a minute
    // Let's check if it is more than an hour
    if ($x >= $t) {

        // More than an hour
        // Let's check if it is more than a day
        if($x >= $d) {

            // More than a day
            // Let's check if it is more than a year
            if ($x >= $f) {

                // More than a year
                // Calculate years
                $a = $x / $f;

                // Get everything before the separator '.'
                if (false !== ($cal = strpos($a, '.'))) {
                    $a = substr($a, 0, $cal);
                }

                // $k = what's left
                $k = $x - ($f * $a);

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...

EDIT: Problem now fixed.. Welcome to use the script :D

A quick fix may be:

$string = '15 hours 6 minutes 2 seconds'; $pattern ='/ \d+ \w+$/'; $string = preg_replace($pattern, ' and$0', $string);

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);

You could then do:

$time = array_filter($time); $last = array_pop($time); $string = implode(', ', $time) . ' and ' . $last;
