所以我有如下字符串：
1)what is capital of india?a)bangloreb)delhic)Hyderabad2)what is capital of telangana?a)hydb)khammamc)warangal
我想把它改成：
1)what is capital of India?
A)Bangalore
B)Delhi
C)Hyderabad
2)what is capital of telangana?
A)Hyd
B)khammam
C)waranagal
有人能给我一些建议或暗示吗？
<?php
$data ="1)what is capital of india?a)bangloreb)delhic)Hyderabad2)what is capital of telangana?a)hydb)khammamc)warangal";
$data= str_replace("a)"," A)","$data");
$data= str_replace("b)"," B)","$data");
$data= str_replace("c)"," C)","$data");
$data= str_replace("d)"," D)","$data");
echo str_replace("2)"," <br/>2)","$data");

运行此代码将对您有所帮助。
使用@Avinash Raj答案，以下是代码片段：
$str = "1)what is capital of india?a)bangloreb)delhic)Hyderabad2)what is capital of telangana?a)hydb)khammamc)warangal";
$str = preg_replace('~(?='w'))~', '<br/>', $str );
echo $str ;
预期输出为：
<br/>1)what is capital of india?<br/>a)banglore<br/>b)delhi<br/>c)Hyderabad<br/>2)what is capital of telangana?<br/>a)hyd<br/>b)khammam<br/>c)warangal
维奇结果：
1）印度的首都是什么
a）班加罗尔
b）德里
c）海得拉巴
2）特伦甘纳的首都是什么
a）hyd
b）khammam
c）warangal
更新：
代码已更新为首字母大写。
<?php
$str = "1)what is capital of india?a)bangloreb)delhic)Hyderabad2)what is capital of telangana?a)hydb)khammamc)warangal";
$str = preg_replace('~(?='w'))~', '|', $str );
$arr = explode('|', $str);
for ($x = 0; $x < count($arr); $x++) {
$value = $arr[$x];
$arr[$x] = ucfirst($value);
}
$arr = implode("<br/>", $arr);
print_r($arr);
