I actually use XSLT for some stuff at home: got a lot of data, I manage most it in XML with some in JSON because a real NoSQL database would be awkward to hand-edit like I need, and want to render it into a viewable form. Add XSLT and throw in PHP's function bindings and you can do just about anything. Downside: super inefficient, so complicated processing takes a while. Early 2000s, give or take, I even experimented with a XML-based website - as in the server responded with XML, not HTML. It worked very well. In fact, after getting back into it for the above project stuff, I'll very likely do it again for a couple smaller projects. Because the simplicity of editing data in XML lets me do whatever I want without having to run a database server or make table schema changes or build CRUD tools.1 point

Not that anyone has been using it this decade - or century, even - but there's a technology that exists which is designed for transforming XML into HTML as you just did. It's called XSLT. You can do it fully within PHP, but here's a demo without. kjv.xml <?xml version="1.0"?> <?xml-stylesheet href="kjv.xslt" type="text/xsl"?> <root> <book num="I don't know"> <chapter num="17"> <verse num="1">And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart,</verse> <verse num="2">And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light.</verse> <verse num="3">And, behold, there appeared unto them Moses and Elias talking with him.</verse> <verse num="4">Then answered Peter, and said unto Jesus, Lord, it is good for us to be here: if thou wilt, let us make here three tabernacles; one for thee, and one for Moses, and one for Elias.</verse> <verse num="5">While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him.</verse> <verse num="6">And when the disciples heard <i>it,</i> they fell on their face, and were sore afraid.</verse> <verse num="7">And Jesus came and touched them, and said, <span class="j">Arise, and be not afraid. </span></verse> <verse num="8">And when they had lifted up their eyes, they saw no man, save Jesus only.</verse> <verse num="9">And as they came down from the mountain, Jesus charged them, saying, <span class="j">Tell the vision to no man, until the Son of man be risen again from the dead. </span></verse> <verse num="10">And his disciples asked him, saying, Why then say the scribes that Elias must first come?</verse> <verse num="11">And Jesus answered and said unto them, <span class="j">Elias truly shall first come, and restore all things. </span></verse> <verse num="12"><span class="j">But I say unto you, That Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them. </span></verse> <verse num="13">Then the disciples understood that he spake unto them of John the Baptist.</verse> <verse num="14">And when they were come to the multitude, there came to him a <i>certain</i> man, kneeling down to him, and saying,</verse> <verse num="15">Lord, have mercy on my son: for he is lunatick, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.</verse> <verse num="16">And I brought him to thy disciples, and they could not cure him.</verse> <verse num="17">Then Jesus answered and said, <span class="j">O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me. </span></verse> </chapter> </book> </root> kjv.xslt <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html" /> <xsl:template match="/"> <html> <body> <xsl:apply-templates select="/root/book" /> </body> </html> </xsl:template> <xsl:template match="book"> <h1>Book <xsl:value-of select="@num" /></h1> <xsl:apply-templates select="chapter" /> </xsl:template> <xsl:template match="chapter"> <h2>Chapter <xsl:value-of select="@num" /></h2> <ol start="{verse[1]/@num}"> <xsl:apply-templates select="verse" /> </ol> </xsl:template> <xsl:template match="verse"> <li><xsl:apply-templates /></li> </xsl:template> <xsl:template match="b | i | span"> <xsl:copy-of select="." /> </xsl:template> </xsl:stylesheet> In a browser, which you might have to run through a webserver depending on your browser security settings, (you can see the italics in verses 6 and 14; the spans are invisible but they are present)

this checks the datatype of the variable, not what's in the variable. get, post, cookies are by definition strings, regardless of what value they hold. change this to is_numeric().1 point

Looks like @gizmola missed a right square bracket on the second $_GET value. Try: if (!isset($_GET['t']) || !is_int($_GET['t']) || $_GET['t'] < 0) { header('Location: http://www.baltimorebeach.com'); }1 point

the most likely reason that GetAllData() returns a null is because $_SESSION['CounterValue'] isn't one of the expected values and none of the conditional code in the function is being executed. since there's no corresponding undefined index error massage, the session variable is set, but is probably an empty string. what does using var_dump($_SESSION['CounterValue']); show? note: session variables are inputs to the code for a page. you need to validate them before using them. if they are not valid, you either need to use a default value and continue or prevent running any code that's dependent on their value. if they are due to a user action, you need to setup and display a message for the user letting them know what to do to correct the problem. if they are set internally, you have a programming mistake somewhere that needs to be found and fixed. edit: the global keyword only has meaning inside a function. the global $View; line in your main code does nothing and should be removed.1 point
