How to write Multi-Line Strings in PHP ?
Multi-Line Strings can be written in PHP using the following ways.
- Using escape sequences: We can use the n escape sequences to declare multiple lines in a string.PHP Code:
PHP
<?php
$var
=
"GeeksnFornGeeks"
;
echo
$var
;
?>
Output:
Geeks For Geeks
- Using concatenation assignment operator: We can use the concatenation assignment operator .= to concatenate two strings and the PHP_EOL to mark the end of the line.
PHP Code:
PHP
<?php
$s1
=
"Geeks"
. PHP_EOL;
$s2
=
"For"
. PHP_EOL;
$s3
=
"Geeks"
;
$s1
.=
$s2
.=
$s3
;
echo
$s1
;
?>
Output:
Geeks For Geeks
- Using Heredoc and Nowdoc Syntax: We can use the PHP Heredoc or the PHP Nowdoc syntax to write multiple-line string variables directly. The difference between heredoc and nowdoc is that heredoc uses double-quoted strings. Parsing is done inside a heredoc for escape sequences, etc whereas a nowdoc uses single-quoted strings, and hence parsing is not performed.Note: The delimiter in the heredoc and nowdoc syntaxes must always be at the beginning of a line without any spaces, characters, etc.
PHP Code:
PHP
<?php
$s1
=<<<EOD
Geeks
tFor
Geeks
EOD;
echo
$s1
;
echo
"n"
;
$s2
=<<<
'EOT'
Geeks
tFor
Geeks
EOT;
echo
$s2
?>
Output:
Geeks For Geeks Geeks tFor Geeks
