比如
<code>wordWordWordWord </code>
分隔成数组
<code>word,Word,Word,Word </code>
正则该怎么写
比如

分隔成数组

正则该怎么写
<code><?php
$a = 'wordWordWordWordYelloHelloTest';
var_dump(preg_split('/(?=[A-Z])/', $a));
</code>结果:
<code>array(7) {
[0]=>
string(4) "word"
[1]=>
string(4) "Word"
[2]=>
string(4) "Word"
[3]=>
string(4) "Word"
[4]=>
string(5) "Yello"
[5]=>
string(5) "Hello"
[6]=>
string(4) "Test"
}
</code>
楼上的正则有够复杂，来个简单的，先替换再切割：
<code><?php
$str = "wordWordWordWord";
$splitChar = ",";
$formatStr = preg_replace("/([A-Z])/", ",\\1", $str);
$wordList = explode($splitChar, $formatStr);
print_r($wordList);
</code>
