== preg_split ==

When you want to explode a message by spaces, you may want to use the preg_split function, because sometimes an enduser accidently sends two spaces. For example, he sends DEPERS 1623HV. Your script expects a ZipCode at the first position, but because of the spaces it will be an other position. This preg_split solves this issue.

<source lang="php">
$lMessageParts = preg_split("/[\s]+/", $aObjMoMessage->MESSAGE);
</source>

If you want to split the message for words only, then you can use this code:

<source lang="php">
$lMessageParts = preg_split("/[^A-Za-z]+/", $lMbiMoMessage->MESSAGE);
</source>

This method makes sure that when the user sends "IAMOR: PAUL & NICOLE", the output will still be Array("IAMOR", "PAUL", "NICOLE"), which is perfect if you want to process the words only. This preg is being used in the iTV games.

== SimpleXML attributes ==

To fetch the attribute of an element, try this:

$objXml->element->attributes()->name;

<source lang="xml">
<?xml version="1.0" encoding="UTF-8"?>
<test>
<element name="showcase">true</element>
</test>
</source>

To print out ''showcase'' here, echo $objXml->element->attributes()->name;

<source lang="xml">
<?xml version="1.0" encoding="UTF-8"?>
<test>
<element name=\"showcase\">true</element>
<other>
<jadi test=\"true\">okay then!</jadi>
</other>
</test>
</source>

To print out "true" from the jadi element, use echo $objXml->other->jadi->attributes()->test;

== CDATA with dom document ==

To create a CDATA element when using DOM Document in PHP, you can add the CDATA section right after the appendchild. Example:

<source lang="php">
$objXml = new DOMDocument("1.0", "UTF-8");
$lRequests = $objXml->appendChild(new DOMElement("Requests"));
$lRequests->appendChild(new DOMElement("foo"))->appendChild($objXml->createCDATASection("bar"));
echo $objXml->saveXML();
</source>

Outputs:

<source lang="xml">
<?xml version="1.0" encoding="UTF-8"?>
<Requests><foo><![CDATA[bar]]></foo></Requests>
</source>
