[SOLVED] What is $this => $something?

[Nexy]

Around this site, I see people with code that have:

 

$this => something here;

$this => something here;

$this => something here;

$this => something here;

etc....

 

Just wondering what is it called and any good place I can learn? If it just means greater than or equal to, then I don't understand why people use it this way. D:

It's $this->something

 

Read the PHP manual on object oriented programming.  It's a big topic so I'm just pointing you in the right direction.

It's a call to a class. You can read up on them here http://us3.php.net/zend-engine-2.php

it's to specify a key/value pair for associative arrays. Example:

 

// keys are a, b, c values are 1, 2, 3
$blah = array('a' => 1, 'b' => 2, 'c' => 3);

// using a foreach loop to loop through array elements
foreach ($blah as $letter => $number) {
   echo "key: $letter value: $number <br />";
}

Thank You, I'll read up on it.
