例如，我有这个字符串："iCanSeeBluePeople"，我需要它用大写字母和第一个单词（以小写开头）将其分隔成数组，所以我会收到类似["i","Can","See","Blue","People"] 的数组
字符串可以像"grandPrix2009"=>["grand","Prix","2009"]、"dog"=>["dog"]、"aDog"=>["a","Dog"]等
我发现这个代码很好用，但我不适用于数字，并且忽略了第一个小写字母：
<?
$str="MustangBlueHeadlining";
preg_match_all('/[A-Z][^A-Z]*/',$str,$results);
?>
感谢的帮助
您可以使用正则表达式/[a-z]+|[A-Z]+[a-z]*|[0-9]+/。
<?
$str="thisIsATestVariableNumber000";
preg_match_all('/[a-z]+|[A-Z]+[a-z]*|[0-9]+/',$str,$results);
print_r($results);
?>
结果：
Array
(
[0] => Array
(
[0] => this
[1] => Is
[2] => ATest
[3] => Variable
[4] => Number
[5] => 000
)
)
如果要将ATest分为A和Test，请使用/[a-z]+|[A-Z][a-z]*|[0-9]+/。
<?
$str="thisIsATestVariableNumber000";
preg_match_all('/[a-z]+|[A-Z][a-z]*|[0-9]+/',$str,$results);
print_r($results);
?>
结果：
Array
(
[0] => Array
(
[0] => this
[1] => Is
[2] => A
[3] => Test
[4] => Variable
[5] => Number
[6] => 000
)
)
