PHP echo and print Statements
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.
Difference between echo and print echo
You can see the difference between echo and print statements with the help of the following programs.
For Example (Check multiple arguments)
You can pass multiple arguments separated by a comma (,) in echo. It will not generate any syntax error.
PHP Example
?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 Example
?php
$fname = "Gunjan";
$lname = "Garg";
print "My name is: ".$fname,$lname;
?>
For Example (Check Return Value) echo statement does not return any value. It will generate an error if you try to display its return value.
PHP Example
?php
$lang = "PHP";
$ret = echo $lang." is a web development language.";
echo "";
echo "Value return by print statement: ".$ret;
?>
As we already discussed that print returns a value, which is always 1.
PHP Example
?php
$lang = "PHP";
$ret = print $lang." is a web development language.";
print "";
print "Value return by print statement: ".$ret;
?>
