PHP Echo/Print Statements

In PHP, you can use the echo or print statements to output content to the browser or the command line. Both echo and print can be used to achieve the same result, which is displaying text or variables.

Here are some examples of using echo and print statements in PHP:

Example 1: Outputting a string using echo

php

echo "Hello, world!"; // Outputs: Hello, world!

Example 2: Outputting a string using print

php

print "Hello, world!"; // Outputs: Hello, world!

Both echo and print can also output the values of variables:

Example 3: Outputting a variable using echo

php

$name = "John";
echo "Hello, " . $name . "!"; // Outputs: Hello, John!

Example 4: Outputting a variable using print

php

$name = "John";
print "Hello, " . $name . "!"; // Outputs: Hello, John!

It’s worth noting that echo is a bit faster than print, but the difference is usually negligible. Additionally, echo can take multiple parameters separated by commas, while print only accepts a single argument.

Example 5: Using multiple parameters with echo

php

$name = "John";
$age = 25;
echo "Hello, ", $name, "! You are ", $age, " years old."; // Outputs: Hello, John! You are 25 years old.

Overall, echo and print are both useful for outputting content in PHP, and you can choose whichever one you find more convenient for your needs.
