We frequently use the echo statement to display the output. There are two basic ways to get the output in PHP:
echo and print are language constructs, and they never behave like a function. Therefore, there is no requirement for parentheses. However, both the statements can be used with or without parentheses. We can use these statements to output variables or strings.
You can see the difference between echo and print statements with the help of the following programs.
You can pass multiple arguments separated by a comma (,) in echo. It will not generate any syntax error.
<?php $fname = "Gunjan"; $lname = "Garg"; echo "My name is: ".$fname,$lname; ?>
Output:
It will generate a syntax error because of multiple arguments in a print statement.
<?php $fname = "Gunjan"; $lname = "Garg"; print "My name is: ".$fname,$lname; ?>
Output:
echo statement does not return any value. It will generate an error if you try to display its return value.
<?php $lang = "PHP"; $ret = echo $lang." is a web development language."; echo "</br>"; echo "Value return by print statement: ".$ret; ?>
Output:
As we already discussed that print returns a value, which is always 1.
<?php $lang = "PHP"; $ret = print $lang." is a web development language."; print "</br>"; print "Value return by print statement: ".$ret; ?>
Output:
