????? <img? id="img" src="http://localhost/uc_server/avatar.php?uid=2&size=big" width="110px" height="160px" />其中uid=2? ? 其實(shí)是想給uid賦值為超全局變量$_SESSION的值，怎么在src屬性中將uid=“超全局變量$_SESSION”的值

<?php
$directoryAsset = isset($_SESSION['what'])?'upload/customers/'.$_SESSION['what']:'';
?>
src="http://localhost/uc_server/avatar.php?uid=$directoryAsset&size=big"

慕仔8661472就是想將<img id="img" src="http://localhost/uc_server/avatar.php?uid=2&size=big" width="110px" height="160px" /> 變成 <img id="img" src="http://localhost/uc_server/avatar.php?uid=$_SEESION&size=big" width="110px" height="160px" /> 但是這樣寫(xiě)會(huì)有一個(gè)問(wèn)題就是src中的整個(gè)字符串會(huì)原封不動(dòng)的輸出，而不是自動(dòng)解析$_SESSION的值
