php unset 數組不管用

$exchangeName= array (    9000 =>        array (            0 => '正常儲值1',            1 => 4.99,        ),    9003 =>        array (            0 => '正常儲值4',            1 => 49.99,        ),    9152 =>        array (            0 => '一次性促銷4',            1 => 99.99,        ),);$qin = var_export($exchangeName);//echo $qin;$contents="444,name,0.99|555,name,9.99";$packageArray=explode('|', $contents);unset($exchangeName);foreach ($packageArray as $packageValue){ $temp=explode(',', $packageValue); $exchangeName[$temp[0]]=array($temp[1],$temp[2]);}echo var_export($exchangeName,true);

回複內容：

$exchangeName= array (    9000 =>        array (            0 => '正常儲值1',            1 => 4.99,        ),    9003 =>        array (            0 => '正常儲值4',            1 => 49.99,        ),    9152 =>        array (            0 => '一次性促銷4',            1 => 99.99,        ),);$qin = var_export($exchangeName);//echo $qin;$contents="444,name,0.99|555,name,9.99";$packageArray=explode('|', $contents);unset($exchangeName);foreach ($packageArray as $packageValue){ $temp=explode(',', $packageValue); $exchangeName[$temp[0]]=array($temp[1],$temp[2]);}echo var_export($exchangeName,true);

unset是釋放指定的變數。你直接unset二維數組肯定不行啊！參考手冊

你這下面不是有重新的賦值了嗎
