There's several ways:
1) You can put square brackets on the end of a variable to create an array key inside that variable:
$names['first'] = "john"
$names['last'] = "smith"
2) You can use the array function:
$names = array('first' => "john", 'last => "smith");
a lot of people set this function out like this:
$names = array(
'first' => "john",
'last' => "smith"
);
it makes it easier to read
hope this helps
To empty an array in PHP you need to use the unset function like shown below: <?php $array = array('hello', 'hi', 'weee'); unset($array); // empty ?>
To find the size of an array in PHP you can either use the count() function or the sizeof() function as they will produce the same result. <?php $array = array(1, 2, 3, 4, 5, 6, 7); echo count($array); // outputs 7 echo sizeof($array); // outputs 7 ?>
To pick random results from an array in PHP you will need to use the array_rand() function, you can select the amount of results you wish it too select too. <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); $rand_results = array_rand($array, 3); // will select 3 random results from the array and store in a new array ?>
build an array of vowels then do a foreach on the array and then explode the string on the array value and the answer is -1 of the result
To check if a value is already in an array you will need to use the in_array function like shown below! <?php $values = array("pizza","hello","cheese","fred"); $newvalue = "hello"; if (in_array($newvalue, $values)) { echo "$newvalue is already in the array!"; } ?>

In a database table, the INSERT INTO statement is used to insert new rows. Let's create a SQL query with acceptable values using the INSERT INTO statement, and then run it by passing it to the PHP mysqli query() function to insert data into the table.

What you need is a form (By HTML), an Database and table in Mysql and PHP to insert data from your form to the table. mysql insert command is: INSERT INTO table_name_here (column1, column2, ..)

Once you submit a form you can use the $_POST[] array to grab the data from a form with PHP. You can then use this data to insert it into a form. Here is an example: <?php if($_POST['submit']){ $text_box_contents = $_POST['comments']; echo ' <select> <option>'.$text_box_contents .'</option> </select>'; }else{ echo ' <form method="post" action="$_SERVER['self']"> <textarea name="comments" cols="40" rows="5"> hostmysite.com Enter your comments here... </textarea><br> <input type="submit" value="Submit" /> </form>'; } ?>

To shuffle an array in PHP is easy to do, all you need to use is the shuffle() function like shown below: <?php $array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10); shuffle($array); // array results will be randomly shuffled ?>
In the controller file add some code. For eg. ItemsController.php will have the following code <?php public function add() { if(!empty($this->data)) { $this->Item->set($this->data); if($this->Item->validates($this->data)) { if($this->Item->save($this->data)) { $this->Session->setFlash("<strong>Item added.</strong>"); $this->redirect(array('action' => 'view')); // put your 'yourfile.ctp' in place of 'view' } } } ?> This should send the data object to model file named Item.php which would later save the data to database.

Answer: Use the unshift() Method You can use the unshift() method to easily add new elements or values at the beginning of an array in JavaScript. This method is a counterpart of the push() method, which adds the elements at the end of an array. However, both method returns the new length of the array To learn more about data science please visit- Learnbay.co
