ZerOne: October 2012

Google's big October 29th product launches apparently outed

A few days ago, Google sent out invitations to a press event to be held on October 29th in New York City. We noted that this event was happening on the same day as Microsoft's Windows Phone 8 press events in San Francisco and other parts of the world.

Now TheNextWeb.com reports it has information on all of the new product reveals that Google will announce at this October 29th media junket, and quite frankly it sounds pretty impressive, if all of this is true. The story says the information comes from an internal video shown to Google employees.

It's not a surprise to learn that Google is said to be revealing a 32 GB version of its previously released Nexus 7 tablet, made by Asus, at this event. The tablet will be available in both WiFi only and a WiFi/3G version, according to the story. It adds that Google will also reveal a 10 inch tablet, made by Samsung, that has the code name "Manta" but might be called the Nexus 10 when it is actually released.

The Manta will reportedly have a screen resolution of 2560x1600 and 300 PPI, compared to the current iPad which has "just" 264 PPI. The story also reports that Google will reveal the LG Nexus 4 smartphone at the event, with a 4.7 inch 1280x768 display, a quad-core 1.5 GHz Qualcomm Snapdragon processor, 2 GB of RAM and more.

Both the Manta tablet and the LG Nexus 4 will reportedly be running on Android 4.2, which among other new features will allow users to access Google Play downloaded content from a widget and a way for one tablet to be shared by several people who can then access their own emails and apps.

PHP Syntax

Unknown 23:25 Add Comment

The PHP script is executed on the server, and the plain HTML result is sent back to the browser.

Basic PHP Syntax

A PHP script always starts with <?php and ends with ?>. A PHP script can be placed anywhere in the document.

On servers with shorthand-support, you can start a PHP script with <? and end with ?>.

For maximum compatibility, we recommend that you use the standard form (<?php) rather than the shorthand form.

<?php
?>

A PHP file must have a .php extension.

A PHP file normally contains HTML tags, and some PHP scripting code.

Below, we have an example of a simple PHP script that sends the text "Hello World" back to the browser:

<html>
<body>

<?php
echo "Hello World";
?>

</body>
</html>

Each code line in PHP must end with a semicolon. The semicolon is a separator and is used to distinguish one set of instructions from another.

There are two basic statements to output text with PHP: echo and print.

In the example above we have used the echo statement to output the text "Hello World".
Comments in PHP

In PHP, we use // to make a one-line comment or /* and */ to make a comment block:

<html>
<body>

<?php
//This is a comment

/*
This is
a comment
block
*/
?>

</body>
</html>
