How to search and remove sub arrays from array if string not found in list-CodePudding

I'm stuck. I'm trying to search the array and to look for keywords at the second level of the array, like ["Secondary_Volunteering__c"] and Referral_Source_within_CF__c. If those values are found then keep them, if not delete them.

I have created the following but it comes back blank.

Any guidance will be appreciated.

foreach($getAllCustomerCustomFields as $k => $v) {
    if(!in_array(["Secondary_Volunteering__c"], $v) && !in_array("Referral_Source_within_CF__c", $v))
        unset($getAllCustomerCustomFields[$k]);
}

foreach($getAllCustomerCustomFields as $fields){
    foreach($fields as $field){
        echo( '<strong>'.$field["FIELD_LABEL"].'</strong><br>');
        foreach ($field["CUSTOM_FIELD_OPTIONS"] as $cfield){
        echo($cfield["OPTION_VALUE"].'<br>');

        }
         echo('<br>');
    }
   
}

This is the PHP array.

array(1) {
  ["CUSTOMFIELDS"]=>
  array(46) {
    ["Secondary_Volunteering__c"]=>

CodePudding user response：

If I understand you correctly, it looks like array_filter will help you here...

<?php

$getAllCustomerCustomFields = array_filter($getAllCustomerCustomFields, function($key) {
    return $key == 'Secondary_Volunteering__c' || $key == 'Referral_Source_within_CF__c';
}, ARRAY_FILTER_USE_KEY)

This basically filters off (reduces) all the unwanted keys of the array
