PHP Simple HTML DOM Parserで文字化けするときの対処法

Posted at

Simple HTML DOMで、外部のファイルを扱う場合、

// Create DOM from URL or file
$html = file_get_html('http://www.google.com/');

と書くことが多い。

でも日本語サイトの場合は、文字化けする可能性が高いので、

mb_language('Japanese');

$source = file_get_contents('http://www.google.com/');
$source = mb_convert_encoding($source, 'utf8', 'auto');

$dom = str_get_html($source);

とやった方がいい。
