Laravel 4 で s3に htmlファイルを アップロードして、content-typeとcharsetもutf8で設定する。

upload_s3.php

<?php

// ControllerとかCommandとかのなかに適当に以下を書く

$image = Image::findOrFail($ad->image_id);
$content_type = explode(";",$image->spec)[0];
$spec_ext = explode("/", $content_type)[1];

$ad_array = $ad->toArray();
$display_text = "あああ表示文字";
$click_url = "http://example.com/test.html";


$pwd = getcwd();
$localpath_html = "$pwd/test.html";

$html_txt = '
<li>
    <a href="'.$click_url.'">
    <img src="http://'. $bucket. $image_key .'" width= "48" height= "48">
    <p>'. str_replace("\r\b","<br/>",$display_text) .'</p>
    </a>
</li>
';
file_put_contents($localpath_html, $html_txt);

$bucket = 'バケット名';
$s3 = AWS::get('s3');
$html_upload_path = "/test/test.html";
$s3 = AWS::get('s3');
$s3->putObject(array(
    'Bucket' => $bucket,
    'Key' => $html_upload_path,
    'SourceFile' => $localpath_html,
    'ContentType' => 'text/html; charset=utf-8',
));
?>
