strange result in "echo" (php/ajax)

Hi

I wana check value of an input text for validation by ajax.

I read a great tutorial in w3schools.com in here:
[url]http://w3schools.com…ax_database.asp[/url]

and I changed it for my business.

so I have 3 file:
in index.php

[CODE]<div class=”fieldwrapper”>
<div class=”thefield 1″ id=”idn1″>
<input name=”password” type=”password” value=”” size=”30″ onchange=”showUser(this.value)”/>
</div>
</div>[/CODE]

and and some of code in second file: load.js

[CODE]
function showUser(str)
{
if (str==””)
{
document.getElementById(“idn1″).innerHTML=””;
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject(“Microsoft.XMLHTTP”);
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById(“idn1”).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open(“GET”,”getuser.php?q=”+str,true);
xmlhttp.send();
}[/CODE]

and finaly, in third file: (external php): idn1.php

[CODE]
<?php
$q=$_GET[“q”];

if(strlen($q) <6 && strlen($q) <> NULL)
{
echo “<p> it’s true </p>”;
}

else
{

echo “<p> it’s true </p>”;
}
[/CODE]

this php/ajax code works great…

Now I wana write a single “html tag” in my code in idn1.php (not double html tag)
like this:

[CODE]
<?php
$q=$_GET[“q”];

if(strlen($q) <6 && strlen($q) <> NULL)
{
echo “<p> it’s true </p>”;

}

else
{
echo “<div>”;
echo “<p> it’s true </p>”;
}

[/CODE]

for (strlen($q) >=6), when I look in index.php html source code (by browser [google chorme- [inspect element])
I expect view these result:

[CODE]
<div>
<p>it’s true</p>
[/CODE]

but i get these strange result:

[CODE]
<div>
<p>it’s true</p>
</div>[/CODE]

I hope u got my means.
I don’t want print [COLOR=”Red”]</div> tag[/COLOR] ….I just wana see[COLOR=”red”] <div> tag[/COLOR] in my html source code.
what can I do to solve this problem?

Also in #PHP _↴
