PHP 代码将多行字符串转换为键值对格式

$aa='a:aa haa b:bb hbb c:cc hcc';

//先将文本按行分割成数组 $lines = explode("\n", $aa);

//遍历每一行，将每行按冒号分割成键值对，然后拼接成新的字符串，并存入新数组 $newLines = array(); foreach ($lines as $line) { $kv = explode(":", $line); $newLines[] = $kv[0] . ":" . $kv[1] . ":" . $kv[2]; }

//将新数组按行拼接成字符串 $result = implode("\n", $newLines);

echo $result;
