實現原理先算出該點周圍的矩形的四個點，然後使用經緯度去直接匹配資料庫中的記錄。 //擷取周圍座標 public function returnSquarePoint($lng, $lat,$distance = 0.5){ $earthRadius = 6378138; $dlng = 2 * asin(sin($distance / (2 * $earthRadius)) / cos(deg2rad($lat))); $dlng =

細數api介面平台，在開發app或者web中不免要用到快遞資料，違章資料等。現在就來數數提供api介面的各類平台以及常用api介面的價格。 彙總資料：api多，免費api也多，但是收費價格貴。Haoservice：資料繁多，價格沒有準確標明多少錢幾次。極速資料：上線不久的網站，數量中等，好在價格便宜。阿凡達資料：今年剛看到的網站，數量中等，價格沒標。易源介面：數量中等，價格沒標

使用ImageMagick，您可以輕鬆，更快地建立縮圖，比使用PHP的容易得多。 // Location to upload main image:$mainDir = $_SERVER['DOCUMENT_ROOT'].'/images/l/';// Location to create the thumb image:$smalDir = $_SERVER['DOCUMENT_ROOT'].'/images/s/';// Command to use:$command =

使用這個php代碼，你就可以知道你伺服器上使用RAM（記憶體）的情況。echo "Initial: ".memory_get_usage()." bytes \n";/* printsInitial: 361400 bytes*/// let's use up some memoryfor ($i = 0; $i $array []= md5($i);}// let's remove half of the arrayfor ($i = 0; $i

將時間轉成幾天前，幾小時等的格式，如： “1天前”，“2個月前”等。 function prettyDate($date){ $time = strtotime($date); $now = time(); $ago = $now - $time; if($ago $when = round($ago); $s = ($when == 1)?"second":"seconds"; return "$when $s ago";
