PHP 載入圖檔

可用於載入內部非web資料夾圖檔,或外部http圖檔

$source_img = '/home/test/test.jpg'; 
//$source_img = 'https://test.jpg';
@$im = imagecreatefromjpeg($source_img);


if(!$im){ // 載入失敗顯示錯誤圖
	$w = 200;
	$h = 200;
	$fontsize = 5; // 1,2,3,4,5 max 5
	$errorstr = 'Image error';
	$im  = imagecreatetruecolor($w, $h); 
	$bgcolor = imagecolorallocate($im, 255, 255, 0);
	$textcolor  = imagecolorallocate($im, 0, 255, 255);

	imagefilledrectangle($im, 0, 0, $w, $h, $bgcolor); // 填滿背景
	$fw = imagefontwidth($fontsize);     // width of a character
	$fh = imagefontheight($fontsize);     // height of a character
	$l = strlen($errorstr);          // number of characters
	$tw = $l * $fw;              // text width
	$th = 1 * $fw;              // text height

	$xpos = ($w - $tw)/2;
	$ypos = ($h - $th)/2;

	imagestring($im, $fontsize, $xpos, $ypos, $errorstr , $textcolor);
}

header("Content-type: image/jpeg");
imagejpeg($im);
imagedestroy($im);
exit;

PHP 多檔案上傳

name 設為[]陣列 ,並在後方加上 multiple

<input type="file" name="userImage[]" id="userImage" multiple>

上傳處理

foreach( $_FILES[userImage][tmp_name] AS $k => $v){
	if(is_uploaded_file($_FILES['userImage']['tmp_name'][$k])) {
		$source_file = $_FILES['userImage']['tmp_name'][$k];
		$target_file = date( "Ymd.His").'_'.$_FILES['userImage']['name'][$k];
		if(move_uploaded_file($source_file,$target_file)) {
			echo $source_file.'上傳成功';
		}
	}
}

Line 自訂分享訊息

<input id="msg_data" type="text" class="form-control " value=""  />
<button onclick="sendLine();">傳Line</button>
function sendLine(){
    var msg = $( "#chat_msg_data" ).val();
    var encoded = encodeURIComponent(msg);
    if(encoded){
        window.location.replace("https://line.me/R/share?text="+encoded );
    }else{
        alert('請輸入訊息');
    }
}

1.文字內容務必urlencode過
2.傳送網址格式可以用
https://line.me/R/share?text={text_message}

https://line.me/R/msg/text/?{text_message}

地址連結開啟Google Map

連結 : https://www.google.com/maps/place/地址

地址建議先用 urlencode 處理過

https://www.google.com/maps/place/100%E5%8F%B0%E5%8C%97%E5%B8%82%E4%B8%AD%E6%AD%A3%E5%8D%80%E5%8C%97%E5%B9%B3%E8%A5%BF%E8%B7%AF3%E8%99%9F

另外一種用法:https://www.google.com/maps/search/?api=1&query=地址

這種用法可套用google map api 達成某些功能

https://developers.google.com/maps/documentation/urls/get-started#search-action

電話超連結

按下連結時會自動開啟撥號程式打電話

連結格式 tel:電話號碼

<a href="tel:<?=$mobile;?>"><?=$mobile;?></a>
<a href="tel:<?=$tel;?>"><?=$tel;?></a>

國際標準

+國碼-電話號碼,台灣號碼如果開頭為0要把0拿掉

$call_mobile_pos = strpos($mobile, '0');
if( $call_mobile_pos === 0) {
    $call_mobile = substr($mobile,1); 
} 
<a href="tel:+886-<?=$call_mobile;?>"><?=$mobile;?></a>

市話區碼開頭為0也要移除

if( strpos($tel, '0' ) === 0) {
     $call_tel = substr($tel,1);
}
<a href="tel:+886-<?=$call_tel;?>"><?=$tel;?></a>

[PHP]phplist 電子報 安裝教學

下載phplist:請至 https://www.phplist.org/ 官網下載
下載後解壓縮,只需要裡面的list資料夾

建立資料庫並設定連線帳號:

mysql> CREATE DATABASE 'phplistdb'; // 建立資料庫
mysql> CREATE USER 'phplist'@'localhost' IDENTIFIED BY 'password'; // 建立連線使用者
mysql> GRANT ALL PRIVILEGES ON phplist.* TO 'phplist'@'localhost'; // 設定使用者權限
mysql> FLUSH PRIVILEGES; // 更新權限

config/config.php 基本設定( 更多設定資料可參考config_extended.php )

 // 語言
 $language_module = 'english.inc';
 // 資料庫位址
 $database_host = 'localhost';
 // 資料庫名稱
 $database_name = 'phplistdb';
 // 資料庫連線使用者
 $database_user = 'phplist';
 // 資料庫密碼
 $database_password = 'password';
 // 如果有更換路徑請加入此設定
 $pageroot = '/lists';

資料庫初始化設定:

至管理介面 http://URL/lists/admin/
按下 Initialise Database 連結
照說明填寫設定欄位就可以使用

[PHP]CURL POST 資料

function CurlPost($PostURL,$PostData,$PStr=null){
     if($PStr){ //使用字串方式post
         foreach ($PostData as $k => $v) {
             $PostStr .= $k.'='.urlencode($v).'&';
             $PostCount++; // 計算共幾個post欄位
         }
         $PostStr = substr($PostStr,0,-1);//消去字尾多餘的 '&'
     }
     $ch = curl_init();
     curl_setopt($ch,CURLOPT_URL, $PostURL); // 設定所要傳送網址
     curl_setopt($ch,CURLOPT_HEADER, false); // 不顯示網頁
     curl_setopt($ch,CURLOPT_POST,1); // 開啟回傳
     curl_setopt($ch,CURLOPT_POSTFIELDS,$PostData); // 將post資料塞入
     curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1); // 開啟將網頁內容回傳值
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); //略過SSL連線驗證
     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); //略過SSL連線驗證
     $GetPost = curl_exec($ch); // 執行網頁
     curl_close($ch); // 關閉網頁
     return $GetPost;
 }

mouseon 放大圖片

HTML:

< img src="image.png" width="90%" class="resizableImage" >

$('.resizableImage').hover(makeBigger, returnToOriginalSize);
function makeBigger() {
     $(this).css({height: '+=10%', width: '+=10%'});
 }
 function returnToOriginalSize() {
