PHP-da HTML teglari bilan ishlash

PHP nuqtai nazaridan HTML teglari oddiy satrlardir. Masalan yozuvni qalin qiladigan <b> tegidan foydalanaylik:

<?php
	echo '<b>qalin</b>';
?>

Bir nechta echo-dan foydalanish mumkin:

<?php
	echo '<b>';
	echo 'qalin';
	echo '</b>';
?>

Birlashtirishdan foydalanish mumkin:

<?php
	$str = 'qalin';
	echo '<b>' . $str . '</b>';
?>

Yoki bunday:

<?php
	$str   = 'qalin';
	$open  = '<b>';
	$close = '</b>';
	
	echo $open . $str . $close;
?>
