Question

例如，我想在数字的每3位数字中加逗号。

$number = 1234567;
// should print 1,234,567

我该怎么做？

更新：请参阅此代码

<?php
/**
 * Get Popularity Text of a Domain via Alexa XML Data
 *
 * @return string|FALSE text or FALSE on error
 */
function alexa_get_rank($domain)
{
    $alexa = "http://data.alexa.com/data?cli=10&dat=s&url=%s";
    $request_url =  sprintf($alexa, urlencode($domain));


    $xml = simplexml_load_file($request_url);
    if (!$xml) {
        return FALSE;
    }

    $nodeAttributes = $xml->SD[1]->POPULARITY->attributes();
    $text = (int) $nodeAttributes['TEXT'];

    $num = number_format($text);

    return $num;
}

仅返回3位数。
