Sorry for my bad English.



I'm trying to make this:



<?php

if( is_array($myarray) && !isset($myarray['mysection'][$name]) )

    {

        $myarray['mysection'][$name] = $data;

    }

?>



But it give me this error: "Parse error: syntax error, unexpected T_IF, expecting ',' or ';' in my file"



Is there any way to do this?

<?php

//Creating a multidimensional array



$theVariable = array("Search Engines" => 

array (

    0=> "http//google.com", 

    1=> "http//yahoo.com",

    2=> "http//msn.com/"),



"Social Networking Sites" =>

array (

    0 => "http//www.facebook.com",

    1 => "http//www.myspace.com",

    2 => "http//vkontakte.ru",)

);



echo "The first array value is " . $theVariable['Search Engines'][0];

?>



-- Output--

The first array value is http://google.com

For newbies like me.



Creating new arrays:-

//Creates a blank array.

$theVariable = array();



//Creates an array with elements.

$theVariable = array("A", "B", "C");



//Creating Associaive array.

$theVariable = array(1 => "http//google.com", 2=> "http://yahoo.com");



//Creating Associaive array with named keys

$theVariable = array("google" => "http//google.com", "yahoo"=> "http://yahoo.com");



Note:

New value can be added to the array as shown below.

$theVariable[] = "D";

$theVariable[] = "E";
