In PHP, Two methods are used to display the output:
Difference Between "echo" and "print" in PHP
PHP "echo" can display multiple arrgument string output. "echo" is a language that is not a function, there is no need to use parentheses but if you use more than one parameter then you need parentheses. it works faster than "print" Or "Echo" can be used with parenthese and without parentheses.
PHP "print" can only single arrgument string output. "print" statement also works like "echo" statement but it contains display one string output.
PHP Echo Statement
PHP "echo" can display many of the data that we get as output on the display such as string, numbers, characters, variables etc. and it will no return value and "echo" works faster than "print".
The following example to understand PHP "echo" Statement:
$student = 'To learning PHP';
$source = 'w3alert.com';
// Variables Inside "echo" Statement.
echo "$student at $source <br />";
// Simple Variable Display.
echo "<br />";
echo "<br />";
// Muliple Arrgument String.
echo $student , $source;
// With parenthese "echo" Statement.
In the above example: $student and $source, there are two varibles with some values each. lets we want to print all variable together using echo. All variable names are set inside an echo statement, this will show the output.
PHP Print Statement
The "print" remains the same as the "echo" statement, but the "print" statement only works with one argument output at a time. it will return 1 value and it is slower than "echo".
The following example to understand Integer PHP "print" Statement:
$welcome = "Hello w3alert!";
$number = "098765545";
// Displaying variables
//With parenthese "print" Statement.
In the above example: Declared two variables $welcome and $number. lets we want to print the variable using print or print(). we simply defined variable inside print statement with or without parentheses.
