Comparing echo and print: Understanding the Differences in PHP

In php echo and print both are used for showing output on the user screen.

Here we are going to discuss some differences between both statements.

1. echo Statement

• we can write echo statement with parenthesis like 'echo()' or without parenthesis 'echo'.
• in the echo we can pass multiple variable in comma separated form to see the output like 'echo $a,$b,$c;'
• echo doesn’t return any value
• echo is faster then print

      Example:

      1.    <?php
                   echo "hello world";
                  // or
                  echo("hello world");
             ?>
      Output: hello world

      2.    <?php
                   $a = "Hi ";
                   $b = "this is ";
                   $c = "Ap here";
                   echo $a,$b,$c;
             ?>
      Output: Hi this is Ap here.

      3.    <?php
                   $a = "Raj";
                   $name = echo $a;             ?>
      Output: Parse error: syntax error, unexpected T_ECHO
    

2. Print Statement

• we can write print statement with parenthesis like 'print()' or without parenthesis 'print'.
• in the print we can not pass multiple variable in comma separated form like echo.
• print statement always returns 1.
• print is slower than echo

      Example:

      1.    <?php
                   print "hello world";
                  // or
                  print("hello world");
             ?>
      Output: hello world

      2.    <?php
                   $a = "Hi ";
                   $b = "this is ";
                   $c = "Ap here";
                   print $a,$b,$c;
             ?>
      Output: Parse error: syntax error

      3.    <?php
                   $a = "Raj";
                   $name = print $a;
                   echo $name;
             ?>
      Output: Raj
