php

$a="很长的东西@很长的东西@。。。";
$b=explode（”@“，$a);
foreach($b as $k=>$v)
{...//录入数据库}
//$a 太长了，删掉一大堆才可以正常执行。
怎么办？

回复讨论(解决方案)

字符串长度应该不是直接原因，估计数组个数太多才是主因
所以，考虑一下流式读入字串，读一部分提取符合规律的部分处理，再读入下一部分，拼接前一部分提取剩余的……按此循环

第一次听说变量太长了还会处理不了，建议举例说明。是怎么个"处理不了"？

应该不会，之前我用excel导入csv格式，然后用vba转换成json字符串，通过页面送给php处理，结果老是出问题，检查的结果就是excel转换的时候有问题，格式出错

{...//录入数据库}

是否是你数据库表，字段设置长度的问题。

是不是你内存太小了啊

是不是没有用 addslashes 导致insert失败？

你写入字段类型设置为text类型，在转换成{ .....}json类型插入数据库字段中

1、按照某种规则切分成多份
2、循环处理每一份

从大神那里知道了原来explode
函数不能长字符后来用正则可以了。
