In PHP three types of strings are using single quoted,double quoted,heredoc



A string literal can be specified in four different ways:

• single quoted
• double quoted
• heredoc
  

Single quoted

The simplest way to specify a string is to enclose it in single quotes (the character ').

echo 'this is a simple string';echo 'You can also have embedded newlines in strings this way as it isokay to do';// Outputs: Arnold once said: "I'll be back"echo 'Arnold once said: "I\'ll be back"';


<?php
echo 'this is a simple string';
echo 'You can also have embedded newlines in strings this way as it isokay to do';
// Outputs: Arnold once said: "I'll be back"echo 'Arnold once said: "I\'ll be back"';
?>




heredoc



<?php
echo <<<EOT My name is "$name".
I am printing some EOT;?>


A third way to delimit strings is the heredoc syntax: <<<. After this operator, an identifier is provided, then a newline. The string itself follows, and then the same identifier again to close the quotation. The closing identifier must begin in the first column of the line. Also, the identifier must follow the same naming rules as any other label in PHP: it must contain only alphanumeric characters and underscores, and must start with a non-digit character or underscore

Variable Declaration

Variables are used for storing a values, like text strings, numbers or arrays.
When a variable is set it can be used over and over again in your script
All variables in PHP start with a $ sign symbol.

The correct way of setting a variable in PHP:

Example :

$txt = "Hello World!";
$number = 16;

Each code line in PHP must end with a semicolon. 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".

PHP is a powerful server-side scripting language for creating dynamic and interactive websites.PHP is the widely-used, free, and efficient alternative to competitors such as Microsoft's ASP.PHP is perfectly suited for Web development and can be embedded directly into the HTML code.The PHP syntax is very similar to Perl and C. PHP is often used together with Apache (web server) on various operating systems.

PHP is the widely-used, free, and efficient alternative to competitors such as Microsoft's ASP.
In our PHP tutorial you will learn about PHP, and how to execute scripts on your server.

PHP code is executed on the server, and the plain HTML result is sent to the browser.


Basic PHP Syntax

A PHP scripting block always starts with .

A PHP scripting block can be placed anywhere in the document.

In everyday life when we deal with time, we speak in seconds, minutes, hours, days, weeks, months, years, decades, centuries, etc.... you get the idea. When PHP deals with time it uses only one measurement, seconds. More specifically it measures time in seconds since January 1, 1970. Once we know how time works in PHP, it becomes easier to add, subtract, and calculate time. Below is a quick guide:

Time in Seconds
1 Minute: 60 seconds
1 Hour: 3,600 seconds
1 Day: 86,400 seconds
1 Week: 604,800 seconds
4 Weeks: 2,419,200 seconds
1 Year: 31,536,000 seconds
1 Decade: 315,360,000 seconds

Now let's put this into practice. Let's say for example you wanted to set a cookie in a user's browser to expire in one year. The way we would calculate this is by adding one year, or 31,536,000 seconds to the current date before setting the cookie:

$Year = 31536000 + time() ;

Perhaps you want to find out what calendar day occurs in a set period of time. This is what is done in pregnancy calendars. In this example we will find the calendar date that occurs in exactly 2 weeks (1209600 seconds) time. $twoweeks = 1209600 + time() ;
echo date("M-d-Y", $twoweeks) ;
