PHP的独立字符串

Question

我有例如字符串："iCanSeeBluePeople"，我需要它由大写字母并与小写开始，所以我会收到阵列像["i","Can","See","Blue","People"]

的 第一个字它分成数组

琴弦可以像"grandPrix2009" =>["grand","Prix","2009"]，"dog" =>["dog"]，"aDog" =>["a","Dog"]等

我发现这个代码WH ICH工作正常，但我并不适用于数字而忽略拳头小写字母：

<? 
$str="MustangBlueHeadlining"; 

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

感谢您的帮助

Answer 1

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ATest被分成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 
    ) 

)
