PHP：如何从此XML获取关联数组？

Question

This is my code so far... needless to say, it's not working :(

$feed = <<< THEXML

<programs>
<program>
<date>2009-04-16</date>
<start_time>17:00</start_time>
<leadtext>hello hello!
</leadtext>
<name>Program 1</name>
<b-line>Comedy</b-line>
<synopsis>Funny stuff
</synopsis>
<url>http://www.domain.tld/program_name</url>
</program>
<programs>
THEXML;


$xml  = (array) simplexml_load_string($feed);

print_r($xml);exit;

Would appreciate any help, have been around the php.net site for hours now and feeling braindead.

Please note that in the example xml above there is just one

 <program>...</program>

tag, but in reality I have one or more of them that I need to use. For example

 <programs>
 <program>...</program>
 <program>...</program>
 <program>...</program>
 </programs>

I figured if I can get one to work then I can loop it, but just thought I would explain what I am going for here.

Thanks in advance!

Answer 1

Assuming the provider gives you valid XML, then you just have to iterate through the programs and use any information you need off it, like so:

<?php
foreach ( $xml as $node ) {
    echo $node->synopsis;
    //or whatever property you want to access on the SimpleXMLElement Object
}

Since you don't have correct XML (being an unclosed <programs> tag, then you might want to modify your script to correct that error like so:

$feed = preg_replace('/<programs>$/', '</programs>', trim($feed));

Answer 2

You're missing the end closing tag.

$feed = <<< THEXML

<programs>
<program>
<date>2009-04-16</date>
<start_time>17:00</start_time>
<leadtext>hello hello!
</leadtext>
<name>Program 1</name>
<b-line>Comedy</b-line>
<synopsis>Funny stuff
</synopsis>
<url>http://www.domain.tld/program_name</url>
</program>
</programs> // <========= here
THEXML;
