I didn't get the correct answer. http://php.flashwebhost.com/sherly/variable.php

<?php

$variable12 = $variable7 + $variable5;
echo $variable7;
echo " + ";
echo $variable5;
echo " = ";
echo $variable12;

<?php

$name = 'Joseph';
$yearBorn = 1975;
$currentYear = 2014;
$age = $currentYear - $yearBorn;

print ("$name is $age years old. ")

<?php

$name = 'Joseph';
$yearBorn = 1975;
$currentYear = 2014;
$age = $currentYear - $yearBorn;

print ("$name is $age years old. ")

Semicolon at end of print statement missing.

print function same as echo, but use echo, forget print. echo is more popular, also there are more ways to print, some complicated, but is not required for most programming project.

print ("$name is $age years old. ")

Proper usage

echo $name . ' is ' .  $age . ' years old. ';

Or

echo "$name  is  $age years old. ";

Advantage of using single quote is PHP know it is just string, so it will be faster. If using double quote, PHP compilter need to look for variable inside the string and convert it to its value, that need more processing time (not much, still do that way as a convention whenever possible).

I was facing difficulty to insert a full stop after a sentence. But I managed to make it work. My code is

<?php

$staffName = 'Ramesh';
$companyName = 'HOSTONNET';

$staffName2 = 'Suresh';

$staffName3 = 'Tom';

echo $staffName . ' is working in ' . $companyName;  echo '.'; echo ' But '; echo $staffName2; echo ' not.' ;

echo '<br>';

echo $staffName3 . ' also working in ' . $companyName . 'for the past 10 years'; echo '.';

Is there any issue with this ?

<?php


$MovieName = 'Mr. Fraud' ;
$Starring = 'Mohanlal, Siddique, Dev Gill, Pallavi, Mia, Manjari' ;
$Director = 'B. Unnikrishnan' ;


echo $MovieName . ' is a malayalam movie, ' . $Director . ' is the Director. ' . $Starring . ' in the lead roles. ' ;

<?php
$brand = 'Sony Xperia J';
$product = 'Mobile';
$android = 'Jelly Bean 4.3';
$shop = 'Flipkart';


echo ' Purchased ' .  $brand . $product . ' from ' . $shop . ' . Android version is ' . $android;

Created code like above.

Result below

Purchased Sony Xperia JMobile from Flipkart . Android version is Jelly Bean 4.3

there is no gap between xperia j and Mobile.

So i just added the . ' ' . to get space.

echo ' Purchased ' . $brand . ' ' . $product . ' from ' . $shop . ' . Android version is ' . $android;



2 doubts


1. Is there any issue if two variables come together ? ($brand . ' ' . $product .)

2. any problem if we use quote ,when we have text and numeric values ($android = 'Jelly Bean 4.3';). I just tried by removing the quote. but showing error message.
