LEARN ABOUT PHP

echo

ECHO(3) 								 1								   ECHO(3)

echo - Output one or more strings

SYNOPSIS

       void echo (string  $arg1, [string  $...])

DESCRIPTION

	Outputs all parameters.

       echo  is not actually a function (it is a language construct), so you are not required to use parentheses with it.  echo (unlike some other
       language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if  you  want
       to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.

       echo  also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. Prior to PHP 5.4.0, this short syn-
       tax only works with the short_open_tag configuration setting enabled.

       I have <?=$foo?> foo.

PARAMETERS

	      o $arg1
		- The parameter to output.

	      o $...
		-

RETURN VALUES

	No value is returned.

EXAMPLES

       Example #1

	      echo examples

	      <?php
	      echo "Hello World";

	      echo "This spans
	      multiple lines. The newlines will be
	      output as well";

	      echo "This spans
multiple lines. The newlines will be
output as well.";

	      echo "Escaping characters is done "Like this".";

	      // You can use variables inside of an echo statement
	      $foo = "foobar";
	      $bar = "barbaz";

	      echo "foo is $foo"; // foo is foobar

	      // You can also use arrays
	      $baz = array("value" => "foo");

	      echo "this is {$baz['value']} !"; // this is foo !

	      // Using single quotes will print the variable name, not the value
	      echo 'foo is $foo'; // foo is $foo

	      // If you are not using any other characters, you can just echo variables
	      echo $foo;	  // foobar
	      echo $foo,$bar;	  // foobarbarbaz

	      // Some people prefer passing multiple parameters to echo over concatenation.
	      echo 'This ', 'string ', 'was ', 'made ', 'with multiple parameters.', chr(10);
	      echo 'This ' . 'string ' . 'was ' . 'made ' . 'with concatenation.' . "
";

	      echo <<<END
	      This uses the "here document" syntax to output
	      multiple lines with $variable interpolation. Note
	      that the here document terminator must appear on a
	      line with just a semicolon. no extra whitespace!
	      END;

	      // Because echo does not behave like a function, the following code is invalid.
	      ($some_var) ? echo 'true' : echo 'false';

	      // However, the following examples will work:
	      ($some_var) ? print 'true' : print 'false'; // print is also a construct, but
							  // it behaves like a function, so
							  // it may be used in this context.
	      echo $some_var ? 'true': 'false'; // changing the statement around
	      ?>

NOTES

       Note

	      Because this is a language construct and not a function, it cannot be called using variable functions.
