本文實例講述了php基於base64解碼圖片與加密圖片還原的實現方法。分享給大家供大家參考。具體實現方法如下：
本例中$data是一段經過base64編碼的圖片。具體代碼如下：
復制代碼 代碼如下:<?php
//文件名:base64.php
$data="/9j/4AAQSkZJRgABAQAAAQABAAD/2wCEABALDA4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9PDkzODdASFxOQERXRTc4UG1RV19iZ2hnPk1xeXBkeFxlZ2MBERISGBUYLxoaL2NCOEJjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY//AABEIADIAMgMBEQACEQEDEQH/xAGiAAABBQEBAQEBAQAAAAAAAAAAAQIDBAUGBwgJCgsQAAIBAwMCBAMFBQQEAAABfQECAwAEEQUSITFBBhNRYQcicRQygZGhCCNCscEVUtHwJDNicoIJChYXGBkaJSYnKCkqNDU2Nzg5OkNERUZHSElKU1RVVldYWVpjZGVmZ2hpanN0dXZ3eHl6g4SFhoeIiYqSk5SVlpeYmZqio6Slpqeoqaqys7S1tre4ubrCw8TFxsfIycrS09TV1tfY2drh4uPk5ebn6Onq8fLz9PX29/j5+gEAAwEBAQEBAQEBAQAAAAAAAAECAwQFBgcICQoLEQACAQIEBAMEBwUEBAABAncAAQIDEQQFITEGEkFRB2FxEyIygQgUQpGhscEJIzNS8BVictEKFiQ04SXxFxgZGiYnKCkqNTY3ODk6Q0RFRkdISUpTVFVWV1hZWmNkZWZnaGlqc3R1dnd4eXqCg4SFhoeIiYqSk5SVlpeYmZqio6Slpqeoqaqys7S1tre4ubrCw8TFxsfIycrS09TV1tfY2dri4+Tl5ufo6ery8/T19vf4+fr/2gAMAwEAAhEDEQA/AJ9Z1G8i1e5SO6mRFbAVXIA4oAqDVL//AJ/J/wDvs0AI2qX/APz+z/8Afw0ARNq2of8AP7cf9/DQBE2sakOl/cf9/DQBC2s6mP8AmIXP/f00Aen27FreMkkkqCfyoA4HXjjW7v8A3/6CgBdK0q41QS/Z3jXy8Z3kjrn0B9KALsnhS/WNmMtudoJwGbP/AKDQBzrGgCFzQBA5oA9etv8Aj1h/3B/KgDz7xA2Ndu/9/wDoKANrwSS0V+BycJ/7NQBkTaNq0MLyyW7qiKWY7xwB170ATW+j219oEt5aySm6hB3xkgjjk44z06UAQXuk29joEN3cySi7n5jiBAAHXJ4z0/mKAOdc0wPYbX/j1h/3F/lSA858RtjX7z/f/oKANvwM37nUSOoCfyagDAl1vUZY2jkvJWRgQyluCD2oA2PCG+zgvdTncpaIm0j++Rzx9On40AJ43geZbXU4XMlq6BR6LnkH8f6UAca7UwPZbX/j1h/3F/lSA8z8TNjxDej/AG/6CmBBYaveaasq2k3liXAf5Qc4zjqPc0AUi9AFqXV7yTTlsGmH2VMEIFUe/JAyaAE/tu/XTTp/ng2pBGxkU989SM9aQGU70Ae12v8Ax6w/7i/yoA8w8UK//CR3uEYjf2HsKYGXtk/55v8AkaAArJ/zzb8jQAwrJ/zzf8jQBGySn/lm/wD3yaQDfJlP/LN/++TQB7Zag/ZYeP4F/lQA9o0LElFJ9xQAvlR/880/75FAB5Uf/PNP++RQAeVH/wA80/75FAB5Uf8AzzT/AL5FMA8qP/nmn/fIoAcBxSA//9k=";
$img=base64_decode($data);
echo $img;
?>
引用圖片的方法:
復制代碼 代碼如下:<img src="base64.php">
運行效果如下圖所示:
