我试图将多维数组的键从CamelCase转换为snake_case,增加的复杂性是某些键有一个我想删除的感叹号.
例如：
$array = array(
'!AccountNumber' => '00000000','Address' => array(
'!Line1' => '10 High Street','!line2' => 'London'));
我想转换为：
$array = array(
'account_number' => '00000000','address' => array(
'line1' => '10 High Street','line2' => 'London'));
我现实生活中的阵列非常庞大,深入人心.任何帮助如何处理这一点非常感谢！
这是我使用的修改函数,取自soulmerge的响应：
原文链接：https://www.f2er.com/php/133263.htmlfunction transformKeys(&$array)
{
foreach (array_keys($array) as $key):
# Working with references here to avoid copying the value,# since you said your data is quite large.
$value = &$array[$key];
unset($array[$key]);
# This is what you actually want to do with your keys:
# - remove exclamation marks at the front
# - camelCase to snake_case
$transformedKey = strtolower(preg_replace('/([a-z])([A-Z])/','$1_$2',ltrim($key,'!')));
# Work recursively
if (is_array($value)) transformKeys($value);
# Store with new key
$array[$transformedKey] = $value;
# Do not forget to unset references!
unset($value);
endforeach;
}
