<?
# First Example
$variable = “test vairable”;
print <<<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;
# Second Example
print “This spans
multiple lines. The newlines will be
output as well”;
?>

Be careful when printing quotes!
Follow these guidelines to use quotes as using the print statement to display strings.
- Use a backslash () within the strings to escape your quotes. Before the quotation mark just place a backslash.
- Inside your strings, use single quotes (‘ ‘)

<?php
// This is wrong approach and produces an error
print “<h1 class=”headerh1“>I love using PHP!</h1>”;
/* The compiler takes first 2 quotes “<h5 class=” as a complete print statement
while start interpreting following code as php’s and not able to identify it
*/
// Escaping the code
print “<h1 class=”headerh1“>I love using PHP!</h1>”;
// Using apostrophe
print “<h1 class=”headerh1“>I love using PHP!</h1>”;
?>
