php解压&；unpack给出的数组包含几个（10309中的9个）未定义的值
我有一个二进制数据字符串，我使用php解压并解压到一个数组中，并使用以下代码（此php页面的完整代码包含在问题的底部）： 最奇怪的是，如果我在完整/原始代码（见页面底部）中手动输入字符串，我会得到未定义的值，而如果我在下面的代码中手动输入通过执行“echo$row[4]”（包含二进制字符串）返回的字符串，则不会产生未定义的值php解压&；unpack给出的数组包含几个（10309中的9个）未定义的值,php,arrays,decode,unpack,compression,Php,Arrays,Decode,Unpack,Compression,我有一个二进制数据字符串，我使用php解压并解压到一个数组中，并使用以下代码（此php页面的完整代码包含在问题的底部）： 最奇怪的是，如果我在完整/原始代码（见页面底部）中手动输入字符串，我会得到未定义的值，而如果我在下面的代码中手动输入通过执行“echo$row[4]”（包含二进制字符串）返回的字符串，则不会产生未定义的值 <?php $string = " /* Copy the string in the spoiler (on this page) here */ "; $
