echo has no return value, print has return value, print with out () and one argument
echo return fast , print gets some time
print ("This ", "string ", "was ", "made ", "with multiple parameters.");- only one argument -> syntax error- print with or without paranthesis
$sum = 10 + print("5"); // Using print as part of an expression
echo $sum; // Output: 11
In PHP, both echo
and print
are used to output strings or variables to the browser or command line. However, there are a few differences between echo
and print
:
Return Value:
echo
does not have a return value, whileprint
has a return value of 1. This means thatprint
can be used as part of an expression, whereasecho
cannot.Syntax:
echo
is a language construct and does not require parentheses. You can use it with or without parentheses, but the latter is more common. On the other hand,print
is a function and requires parentheses.Example:
Multiple Arguments: echo
can take multiple arguments, separated by commas, and it can output all the arguments at once. print
, however, can only accept a single argument.
Example:
echo "Hello", " ", "World!"; // outputs "Hello World!" print "Hello", " ", "World!"; // produces a syntax error
Performance:
echo
is generally considered to be slightly faster thanprint
because it is a language construct and does not have the overhead of being a function.
In practice, echo
and print
are often used interchangeably for simple string output. However, echo
is more commonly used in PHP code due to its flexibility and slightly better performance.
