你好，我有一个像这样的字符串 “ * HQ，6170929875，V1,185905，A，3127.3354，N，07307.6954，E，000.09,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,185915，A，3127.3365，N ，07307.6951，E，002.30,018,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,185925，A，3127.3372，N，07307.6952，E，000.76,000,060718，FFFFB9FF，410， 04,03104,32566＃* HQ，6170929875，V1,185935，A，3127.3369，N，07307.6947，E，000.27,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,185945， A，3127.3371，N，07307.6951，E，000.27,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,185955，A，3127.3377，N，07307.6952，E，000.21,000,060718 ，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,190005，A，3127.3376，N，07307.6950，E，000.17,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875 ，V1,190015，A，3127.3376，N，07307.6953，E，000.07,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,190025，A，3127.3375，N，07307.6955，E， 000.59,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,190035，A，3127.3373，N，07307.6944，E，000.35,000,060718，FFFFB9FF，410,04,03104,32566 ＃* HQ，6170929875，V1,1 90045，A，3127.3378，N，07307.6950，E，000.23,000,060718，FFFFB9FF，410,04,03104,32566＃* HQ，6170929875，V1,190055，A，3127.3381，N，07307.6955，E，000.32,000 ，060718，FFFFB9FF，410,04,03104,32566＃“

我想将所有这些值放在一个数组中。所以我做到了

$array = explode("*",$str);

现在，当我打印数组时，数据是

0索引为空。我想从0索引开始数组。请帮忙。我在这里做错了什么

4 个答案:

答案 0 :(得分：1)

数组的第一个元素为空，因为您的字符串以*开头。要解决这个问题，只需：

$str = "*HQ,6170929875,V1,185905,A,3127.3354,N,07307.6954,E,000.09,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185915,A,3127.3365,N,07307.6951,E,002.30,018,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185925,A,3127.3372,N,07307.6952,E,000.76,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185935,A,3127.3369,N,07307.6947,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185945,A,3127.3371,N,07307.6951,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185955,A,3127.3377,N,07307.6952,E,000.21,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190005,A,3127.3376,N,07307.6950,E,000.17,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190015,A,3127.3376,N,07307.6953,E,000.07,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190025,A,3127.3375,N,07307.6955,E,000.59,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190035,A,3127.3373,N,07307.6944,E,000.35,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190045,A,3127.3378,N,07307.6950,E,000.23,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190055,A,3127.3381,N,07307.6955,E,000.32,000,060718,FFFFB9FF,410,04,03104,32566#";

$arr = explode('*', $str);
array_shift($arr);

print_r($arr);

哪个会产生：

答案 1 :(得分：0)

您可以将其传递给array_filter以删除第一个孩子（索引0）。发生这种情况是因为字符串的第一部分带有*。用*分隔符爆炸表示第一个值为零字符串。

类似的东西：

$array = explode("*",$str);
$array = array_filter($array);

答案 2 :(得分：0)

发生这种情况仅仅是因为您在字符串的开头有一个“ *”字符

*HQ,6170929875,V1,185905,A,3127.3354,N,07307.6954,E,000.09,000,060718,FFFFB9FF,410,04,03104,32566#*....

如果在字符串的开头始终有该字符，则结果数组中将始终有一个空索引0-您需要先删除第一个字符，然后再分解字符串或该数组的第一项。 / p>

答案 3 :(得分：0)

您可以结合使用array_filter删除空值和array_values重新组合数组以从0开始索引：

$str = "*HQ,6170929875,V1,185905,A,3127.3354,N,07307.6954,E,000.09,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185915,A,3127.3365,N,07307.6951,E,002.30,018,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185925,A,3127.3372,N,07307.6952,E,000.76,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185935,A,3127.3369,N,07307.6947,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185945,A,3127.3371,N,07307.6951,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185955,A,3127.3377,N,07307.6952,E,000.21,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190005,A,3127.3376,N,07307.6950,E,000.17,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190015,A,3127.3376,N,07307.6953,E,000.07,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190025,A,3127.3375,N,07307.6955,E,000.59,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190035,A,3127.3373,N,07307.6944,E,000.35,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190045,A,3127.3378,N,07307.6950,E,000.23,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190055,A,3127.3381,N,07307.6955,E,000.32,000,060718,FFFFB9FF,410,04,03104,32566#";
