I want to replace all index keys in a array but i need to do it only with a function like array_map (not with a foreach) and that's why it's a little hard for me.
Actual array :
$array = [
'mc_gross' => 10.17,
'protection_eligibility' => 'Eligible',
'address_status' => 'unconfirmed',
'payer_id' => 'STTAC7UV2CVJ4'
];
Expected array :
$array = [
'McGross' => 10.17,
'ProtectionEligibility' => 'Eligible',
'AddressStatus' => 'unconfirmed',
'PayerId' => 'STTAC7UV2CVJ4'
];
I have already a function to put the first letter in uppercase and remove all '_' :
str_replace(
"_",
"",
implode(
'_',
array_map(
'ucfirst',
explode(
'_',
ucwords(strtolower($key))
)
)
)
);
I have tried with array_walk, but this function can't replace index key, only value... :
array_walk($array, function ($value, &$key) {
$key = str_replace("_", "", implode('_', array_map('ucfirst', explode('_', ucwords(strtolower($key))))));
});
Thanks in advance for your help.
