I have created a custom block and when I try to access a method from my block I get:

exception 'Exception' with message 'Notice: Undefined variable: this­ in /Applications/XAMPP/xamppfiles/htdocs/mag19/app/design/frontend/vish/default/template/Vish/sizecheck/sizecheck.phtml on line 2' in /Applications/XAMPP/xamppfiles/htdocs/mag19/app/code/core/Mage/Core/functions.php:232

My sizecheck.phtml:

 <?php
$products = $this­->igetText();
?>

<div id="product_list">
 <?php echo($products);?>
</div>

The block:

 <?php
class Vish_SizeCheck_Block_Size extends Mage_Core_Block_Template 
 public function igetText()
 
 return "I am inside `" . get_class(). "` block and it is my first custom block ever !";
 

config.xml:

my sizecheck.xml:

 <?xml version="1.0"?>
<layout version="0.1.0">
 <sizecheck_index_index>
 <reference name="root">
 <action method="setTemplate"><template>page/1column.phtml</template></action>

 <block type="core/template" name="sizecheck.form" as="sizecheck_form" template="Vish/sizecheck/form.phtml"/>
 </reference>
 </sizecheck_index_index>
</layout>

My block declaration in CMS Page:

block type="vish_sizecheck/size" name="sizecheck" template="Librex/sizecheck/sizecheck.phtml"

I can see the class is correctly inherited by:

echo get_class($this);

The solution was rather staring me in the face. Looking at the error,

'Notice: Undefined variable: this­ in...

It was not instantiating the variable $this, even though the line was set as:

 <?php
 $products = $this­->igetText();
 ?>

Debugging this line further it revealed there was a hidden character:

So, deleting this line and retyping the line got everything working.
