我正在嘗試顯示存儲(chǔ)在2個(gè)數(shù)組中的圖像的元數(shù)據(jù)…當(dāng)圖像沒有名稱時(shí)，我想顯示“ no-name”。這是我現(xiàn)在顯示這些的方式：$imgs = array('img 1','img 2','img 3','img 4','img 5','img 6');$imgNames = array('name 1','name 2','name 3',);foreach($imgs as $files => $img){    echo 'Image: '.$img.' and Name: '.$imgNames[$files].'<br>';};我期望輸出：Image: img 1 and Name: name 1Image: img 2 and Name: name 2Image: img 3 and Name: name 3Image: img 4 and Name: no-nameImage: img 5 and Name: no-nameImage: img 6 and Name: no-name但實(shí)際輸出是：Image: img 1 and Name: name 1Image: img 2 and Name: name 2Image: img 3 and Name: name 3Notice: Undefined offset: 3 in XX.php …Image:img 4 and Name: Notice: Undefined offset: 4 in XX.php …Image:img 5 and Name: Notice: Undefined offset: 5 in XX.php …Image:img 6 and Name: 如何解決此問題以顯示默認(rèn)的“無(wú)名稱”字符串？
