php用大写分隔字符串

Question

例如，我有这个字符串:"iCanSeeBluePeople"我需要它通过 将它分成数组大写字母和 第一个词以 开头小写所以我会收到像 ["i","Can","See","Blue","People"] 这样的数组

字符串可以像 "grandPrix2009" => ["grand","Prix","2009"] , "dog" => ["dog"] , "aDog" => ["a","Dog"]等等

我发现这段代码工作正常，但我不适用于数字并忽略第一个小写字母:

<?
$str="MustangBlueHeadlining";

preg_match_all('/[A-Z][^A-Z]*/',$str,$results);
?>

感谢帮助

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);
?>

Result :

Array
(
    [0] => Array
    (
        [0] => this
        [1] => Is
        [2] => ATest
        [3] => Variable
        [4] => Number
        [5] => 000
    )

)

使用 /[a-z]+|[A-Z][a-z]*|[0-9]+/如果你想要 ATest分为 A和 Test .

<?
    $str="thisIsATestVariableNumber000";
    preg_match_all('/[a-z]+|[A-Z][a-z]*|[0-9]+/',$str,$results);
    print_r($results);
?>

Result :

Array
(
    [0] => Array
    (
        [0] => this
        [1] => Is
        [2] => A
        [3] => Test
        [4] => Variable
        [5] => Number
        [6] => 000
    )

)
