PHPでの「include」の使い方

Last updated at Posted at 2022-03-13

「include」の使い方

備忘録のためにメモしてます。

各ファイルで共通化している部分をbase.phpに記載します。

base.php
<!DOCTYPE html>
<html lang="ja">
<head>
    <meta charset="UTF-8">
    <title><?php echo $title ;?></title>
</head>
<body>
    <div class="container">
        <?php include $content; ?>
    </div>
</body>

タイトル部分に「$title」、bodyの中身を「$content」とし、呼び出し先の変数に置き換えることも可能。

index.phpファイルからbase.phpを読み込みたいときにincludeを使います。

index.php
<?php

$title = 'HogeeeWorld!!';
$content = __DIR__ . '/content.php';

include 'base.php';

$contentの中身は以下のファイルから読み込んでいます。

content.php
<h1>本文だよ!!</h1>
