php - 如何将 Camel Case 解析为人类可读的字符串？

Question

是否可以将驼峰式字符串解析为更具可读性的字符串。

例如:

• 本地企业 = 本地企业
• CivicStructureBuilding = 市政结构建筑
• getUserMobilePhoneNumber = 获取用户手机号码
• bandGuitar1 = 乐队吉他 1

更新

使用 simshaun正则表达式示例我设法使用此规则将数字与文本分开:

function parseCamelCase($str)
{
    return preg_replace('/(?!^)[A-Z]{2,}(?=[A-Z][a-z])|[A-Z][a-z]|[0-9]{1,}/', ' $0', $str);
}

//string(65) "customer ID With Some Other JET Words With Number 23rd Text After"
echo parseCamelCase('customerIDWithSomeOtherJETWordsWithNumber23rdTextAfter');

PHP手册中str_split的用户注释中有一些例子。

来自 Kevin :

<?php
$test = 'CustomerIDWithSomeOtherJETWords';

preg_replace('/(?!^)[A-Z]{2,}(?=[A-Z][a-z])|[A-Z][a-z]/', ' $0', $test);

这是我为满足您的帖子要求而写的内容:

<?php
$tests = array(
    'LocalBusiness' => 'Local Business',
    'CivicStructureBuilding' => 'Civic Structure Building',
    'getUserMobilePhoneNumber' => 'Get User Mobile Phone Number',
    'bandGuitar1' => 'Band Guitar 1',
    'band2Guitar123' => 'Band 2 Guitar 123',
);

foreach ($tests AS $input => $expected) {
    $output = preg_replace(array('/(?<=[^A-Z])([A-Z])/', '/(?<=[^0-9])([0-9])/'), ' $0', $input);
    $output = ucwords($output);
    echo $output .' : '. ($output == $expected ? 'PASSED' : 'FAILED') .'<br>';
}
