ConFoo: Call for paper is now Open

命令の分離

C や Perl と同様に、PHP でもステートメントを区切りにはセミコロンが必要と なります。PHP コードブロックの終了タグには自動的にセミコロンが含まれていると 認識されます。 従って PHP コードの最終行にはセミコロンを記述する必要はありません。 ブロックの終了タグは、直後に改行がある場合、それを含んだものになります。

<?php
    
echo 'テストです';
?>

<?php echo 'テストです' ?>

<?php echo '終了タグを省略しました';

注意:

ファイル終端における PHP ブロックの終了タグはオプション(任意)です。 includerequire を利用する際には、 終了タグを省略する方が無難です。というのは、そうすることでファイルの最後に 予期せぬ空白文字があらわれてしまうことを防げますし、後でレスポンスに ヘッダを付加することも可能となるからです。また、出力バッファリングを 使用しており、include したファイルの生成する部分の最後に余計な空白を つけたくない場合などにも便利です。

Do not mis interpret

<?php echo 'Ending tag excluded';

with

<?php echo 'Ending tag excluded';
<
p>But html is still visible</p>

The second one would give error. Exclude ?> if you no more html to write after the code.

If you want to keep the newline after a closing tag in the output, just add a space after the closing tag, and the newline will not be ignored.

One thing to remember is, if you decide to omit the closing PHP tag, then the last line of the file should be ended with semi colon. If you add the closing tag then last line doesn't need to end with semi colon.

<?php
echo "First line";
echo
"Last line"

The above code throws error as it neither has closing tag nor semicolon ending. So it should be replaced with either of the below two

<?php
echo "First line";
echo
"Last line";

or

<?
php
echo "First line";
echo
"Last line" ?>

You have been missed semicolon.

Keep in mind if you did not put closing tag, must put semicolon at the end ,

<?php echo '<p>But html is still visible</p>';

The Second line
<?php echo 'This is a test' ?>
will be working properly without throw any errors.

You don't need to put ; at the end of statement if we using a single statement.

If we add more statement only it should be add like this,
<?php
echo 'This is a test'
echo 'This is second line'
?>

See, here also no need to put ; at the end of second line. Because there is no additional statements after.

If you are embedding this in XML, you had better place the ending '?>' there or the XML parser will puke on you.  XML parsers do not like processing instructions without end tags, regardless of what PHP does.

If you're doing HTML like 90% of the world, or if you are going to process/interpret the PHP before the XML parser ever sees it, then you can likely get away with it, but it's still not best practice for XML.
