Difference between echo and print
In PHP, both echo and print are used to output one or more strings to the browser or to the command line. However, there are a few differences between these two language constructs:
- Return value: echo has no return value, while print returns a value of 1. This means that you can use print in an expression, while you cannot use echo.
- Syntax: echo is a language construct and can be used with or without parentheses, while print is a language construct and requires parentheses.
- Performance: echo is generally faster than print because it does not return a value.
- Parameters: echo can take multiple parameters separated by commas, while print can only take one parameter.
For example, consider the following code:
<?php
$name = "John";
echo "Hello, " . $name . "!";
print("Hello, " . $name . "!");
?>
Both echo and print will output the string “Hello, John!” to the browser. However, print will also return a value of 1. In this case, since we are not using print in an expression, the return value is not used.
In most cases, the choice between echo and print is a matter of personal preference, since the differences in performance and syntax are relatively minor.
