从HTML解析XML查询

Essentially, I currently want to parse the XML data that was generated from the html and this was working fine but for some reason will not parse now...gives date of jan 01 1970??...any ideas of problem as coding seems fine?

Thanks a lot in advance!

a date of "jan 01 1970" means that the date was either passed in null or as 0 ... check the raw value of your post to make sure it's coming in as expected.

There's a lot of room for improvement on your code but I'll just stick to the problem your reported. My advice would be for you to change your disp_date function to:

function disp_date($str) {
    return date("M d, Y", strtotime($str));
}

I just picked up a subset of the XML that URL returns and created this small code snippet for demo purposes:

<?php
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8" ?>
<Quote>
<hire>
<loccode>AI001</loccode>
<locname>LONDON - HEATHROW AIRPORT</locname>
<pickupdate>20130819</pickupdate>
<pickuptime>09:00</pickuptime>
<dropbackdate>20130823</dropbackdate>
<dropbacktime>09:00</dropbacktime>
</hire>
</Quote>
XML;

$sxe = new SimpleXMLElement($xml);
echo date("M d, Y",strtotime($sxe->hire->pickupdate));
