php操作字符串转换成数组
今天在php论坛中看到以为朋友发了一个帖子请教php如何把字符串转换成数组;作为php程序员的新一第一反应是联想到explode(),implode()这两个函数。新一也是用里面的函数进行转换成数组的。 con[1]=28selt[1]=1con[2]=29selt[2]=4con[3]=26selt[3]=4 con[4]=30s
今天在php论坛中看到以为朋友发了一个帖子请教php如何把字符串转换成数组;作为php程序员的新一第一反应是联想到explode(),implode()这两个函数。新一也是用里面的函数进行转换成数组的。
con[1]=28&selt[1]=1&con[2]=29&selt[2]=4&con[3]=26&selt[3]=4
&con[4]=30&selt[4]=2&con[5]=4&selt[5]=1&con[6]=11&con[7]=12
上面就是网友需要转换成PHP数组的字符串;下面也是新一提供PHP转换代码
<?php $str = 'con[1]=28&selt[1]=1&con[2]=29&selt[2]=4&con[3]=26&selt[3]=4&con[4]=30&selt[4]=2&con[5]=4&selt[5]=1&con[6]=11&con[7]=12'; $arr = explode('&',$str); $arr2 = array(); foreach($arr as $k=>$v){ $arr = explode('=',$v); $arr2[$k] = $arr[1]; } print_r($arr2); ?> //输出 Array ( [0] => 28 [1] => 1 [2] => 29 [3] => 4 [4] => 26 [5] => 4 [6] => 30 [7] => 2 [8] => 4 [9] => 1 [10] => 11 [11] => 12 ) //第二个 <?php $str = 'con[1]=28&selt[1]=1&con[2]=29&selt[2]=4&con[3]=26&selt[3]=4&con[4]=30&selt[4]=2&con[5]=4&selt[5]=1&con[6]=11&con[7]=12'; $arr = explode('&',$str); $arr2 = array(); foreach($arr as $k=>$v){ $arr = explode('=',$v); $arr2[$arr[0]] = $arr[1]; } print_r($arr2); ?> //输出 Array ( [con[1]] => 28 [selt[1]] => 1 [con[2]] => 29 [selt[2]] => 4 [con[3]] => 26 [selt[3]] => 4 [con[4]] => 30 [selt[4]] => 2 [con[5]] => 4 [selt[5]] => 1 [con[6]] => 11 [con[7]] => 12 )
新一的PHP代码也可以解决字符串转换成数组的问题。最后phper网友应该在手册上面查到了parse_str()函数就可以把字符串转换成PHP数组;下面介绍一下parse_str()函数的说明让自己在脑子中好有印象.
parse_str() 函数把查询字符串解析到变量中。
parse_str(string,array) string:需要转换的字符串; array:返回到一个数组中; 如果没有设置array的话就覆盖同名变量Copy after login

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1.
