Metóda - echo

(PHP 4, PHP 5, PHP 7)

echo() prints one or more strings and does not add a new line after printing. It is not a function, but it is a language construct (echo can be called without parentheses). We can pass more than one parameter (actually the number of parameters is not limited) and then they are printed one by one. However, if we want to use that, we must not call the function with parentheses.

echo has also shortcut syntax that we can use e.g. for printing values in templates. However, we must enable short_open_tag for it. The shortcut syntax looks as follows:

This is only <?= "a sample" ?> code.

Procedurálne

• function echo (string $arg1, string $...) : void

Príklady

<?php
echo "echo without parentheses", "<br />";
echo ("echo() with parentheses");

Using the shortcut syntax (do not forget to enable short_open_tag):

<?= "Using the shortcut syntax" ?>

echo ignores a multiline string. However, we can use \n for a new line:

<?php
echo "Multiline text
is totally
ignored", "<br />";
echo ("Multiline text\nusing special\ncharacters");
