Step 5: Separate Logic From Presentation

• require loads an external php file
  • allows separation of logic and rendering

Step 6: Understanding Arrays

• $myArray[] defines an empty array

• assign values

  $myArray=[  
   'item1',
   'item2'
   ]

• loop over array

   foreach($myArray, as $item){
    // do stuff 
  }
  ?>

  • or

   foreach($myArray,as $item) : ?>
  // do stuff
   endforeach; ?>

Step 7: Associative Arrays

• key value pairs use arrow =>
  • $myArray['key'=>'value]
• add key/value to existing array $myArray['newKey']='newValue'
• add value to non associative array myArray[]='newValue'
• remove key/value unset(myArray['key'])
• dump variable info with var_dump($myVar)
• die('message') stops execution
  • e.g. die(var_dump($myVar))

Step 8: Booleans

• boolean values true / false
  • e.g. $completed = true;
• ternary operator $condition ? 'do this when true' : 'do this when false';
• ucwords('uppercase the first character of each word in a string')
