Print/echo statement
(1) Like python or other programming language, Print in PHP or echo in PHP does the same job i.e printing the statement on the screen
Example
<?php
print "This is php script";
echo " This is php script";
?>
This is php script
This is php script
So it is obvious from the above code, it just print the same character as it is and it is quite simple to use.
(2) Just like any other programming language , print statement print the variable name in the same manner as given below
<?php $x=10 print "This is $x"; echo " This is $x"; ?> This is 10 This is 10
(3) The behavior with single quotes is different
<?php $x=10 print 'This is $x'; echo "This is $x"; ?> This is $x This is 10
So if you enclose the statement in single quotes, variable are not substituted for their value and they are printed as just they are word.
(4) PHP Array can be printed as below
<?php
$oracle_product = array("hyperion", "database", "weblogic", "sql", "EBS");
foreach($oracle_product as $value){
echo $value . "<br>";
}
?>
So you basically iterate through the array using for loop and print the each element in the array. This is quite useful
