Need clarification on syntax

[n1concepts]

Hi,

 

I'm new to PHP and have no knowledge of Zend framework and asking for clarification on this line of code:

 

<?=$this->formValues['capture']?>

 

My question: what purpose is the equal sign in front of the variable serving in this line of code?

 

Note: this line of code is apart of a textbox fied (see full line below):

 

<input type="text" name="tracknum" value="<?=$this->formValues['tracknum']?>

----

 

I need to:

 

1. Change the form so there are THREE textboxes - instead of the one as current.

2. Append the captured data (3 integers from 1st field, then 4 from the second and third text box) back together to make new variable holding 11 digits

3. Then pass that (11 digit) variable back into this field 

<?=$this->formValues['tracknum']?>

so backend scripts can grab and process.

 

Again, I'm not understanding the equal sign in from the variable; what's the purpose/function?

[gristoi]

the ?= is the shorthand version of:

<?php echo $this->formValues['capture']?>

 

it replaces the need for the php and echo syntax

Figured something simple - thanks for explaining!
