這篇文章給大家介紹一鍵生成各種尺寸Icon的php腳本方法,內容非常詳細,感興趣的小伙伴們可以參考借鑒,希望對大家能有所幫助。
實例如下:
<?php /** * @name thumb 縮略圖函數 * @param sting $img_name 圖片路徑 * @param int $max_width 略圖最大寬度 * @param int $max_height 略圖最大高度 * @param sting $suffix 略圖后綴(如"img_x.jpg"代表小圖,"img_m.jpg"代表中圖,"img_l.jpg"代表大圖) * @return void */ function thumb($img_name,$max_width,$max_height,$path,$new_name) { $img_infos = getimagesize($img_name);
