GSMまたはWAV音声の再生時間を取得する方法

function getWavGsmDuration($file_path) {
    $rtn = 0;
    if(file_exists($file_path)){
        $fp = fopen($file_path,"r");
        $size_in_bytes = filesize($file_path);
        fseek($fp, 20);
        $rawheader = fread($fp, 16);
        $header = unpack("vtype/vchannels/Vsamplerate/Vbytespersec/valignment/vbits",$rawheader);
        $rtn = round($size_in_bytes/$header['bytespersec']);
    }
    return $rtn;
}

この関数にファイルパスを渡すと再生時間の秒数を返してくれます。

VirtualBoxでストレージをDドライブに移す手順。

対象のvirtualが電源OFFであることを確認してから、

f:id:senoway:20150806105311p:plain

「ファイル」→「仮想メディアマネージャー」

f:id:senoway:20150806105440p:plain

現在は「場所」とういうところに、

ストレージがあることを確認しておく。

f:id:senoway:20150806105808p:plain

「コピー」をクリックしてコピーするVDIを選択。

f:id:senoway:20150806110558p:plain

コピー場所等指定してコピーまで行う。

上で確認した現在のストレージの場所へいって、現在のVDIは

「解放」してから「除去」する。

 

対象のvirtualを右クリックして、「設定」をクリック。

f:id:senoway:20150806111329p:plain

あとは

「ストレージ」

↓↓↓

「コントローラ:SATA

↓↓↓

追加マーク

↓↓↓

「ハードディスクと追加」

と進んで、さっきコピーしておいたストレージを選らぶ。

 

PHPをexecで非同期で実行させるには。

exec('php test.php > /dev/null &');

こんな感じで、

> /dev/null &

これが必要です。

WordPressでアップロード許可するファイル種類を追加する

自分のテーマのfunctions.php

function allow_upload_psd( $mimes ) {
    $mimes['psd'] = 'image/x-photoshop'; 
    return $mimes;
}
add_filter( 'upload_mimes', 'allow_upload_psd' );

こんな感じで追加する。(PSDの場合の例です。)
