Question

array(1) {
["value"] => array(1000) {
[0]=> array(9) {
["PartitionKey"]=> string(11)"AWT-GPI.com"
["RowKey"]=> string(36) "0024a6ac-6cf1-454a-91b2-15bfec3a3d86"

[1]=> array(9) {
["PartitionKey"]=> string(11) "AWT-GPI.com"
["RowKey"]=> string(36) "002c00c4-e064-43e8-9dd8-319c8d6663bd"

["IP_1"]=> string(0) "" ["Last_Name"]=> string(6) "Wilson"
["Username"]=> string(13) "misterspeed76"
}
}
}
That is the array using this code
$count = count($null_check);
for ($i = 0; $data < $count; $i++) {
foreach ($null_check['value'][$i] as $key => $data) {
$parsed_key = str_replace('_', ' ', $key);
echo $parsed_key.': '.$data.'<br>';
}
echo '<br><br>';
}
I am able to get this output
PartitionKey: AWT-GPI.com
RowKey: 0024a6ac-6cf1-454a-91b2-15bfec3a3d86

Now I want to unset RowKey and Timestamp, however when I do in the foreach statement
unset($null_check['RowKey'];
It doesn't work, I create a separate for each outside or inside, doesn't work, I use the value assigned in the foreach doesn't work. Literally nothing works. This is only a part I have about 30 more just like this. All same format, I just want to remove the RowKey and Timestamp Key, how would I do this?

Answer 1

Use this code
$count = count($null_check);
for ($i = 0; $i <= $count; $i++) {
foreach ($null_check['value'][$i] as $key => $data) {
$parsed_key = str_replace('_', ' ', $key);
echo $parsed_key.': '.$data.'<br>';
if(in_array($key,array('RowKey','Timestamp'))){
unset($null_check['value'][$i][$key]);
}
}
echo '<br><br>';
}
echo '<pre>';
print_r($null_check);
echo '</pre>';

Answer 2

You can use unset() or array_diff_key(), here's how: (just change the \n's to <br>'s)
(Demo)
Input:
$array=[
"value"=>[
["PartitionKey"=>"AWT-GPI.com",
"RowKey"=>"0024a6ac-6cf1-454a-91b2-15bfec3a3d86",
"Timestamp"=>"2016-09-09T20:16:26.8674483Z",
"Email"=>"ginyoung30#gmail.com",
"First_Name"=>"Jennifer",
"Hash"=>"d656d0c21b8f3c14fe03232bb68d1b53",
"IP_1"=>"",
"Last_Name"=>"Young",
"Username"=>"flacobell"
],
["PartitionKey"=>"AWT-GPI.com",
"RowKey"=>"002c00c4-e064-43e8-9dd8-319c8d6663bd",
"Timestamp"=>"2016-09-09T20:19:54.5500874Z",
"Email"=>"Glenn#flavorleague.com",
"First_Name"=>"G",
"Hash"=>"1444a7b2c86506158013d1175137eede",
"IP_1"=>"",
"Last_Name"=>"Wilson",
"Username"=>"misterspeed76"
]
]
];
Method #1:
foreach($array['value'] as $subarray){
foreach(array_diff_key($subarray,['RowKey'=>'','Timestamp'=>'']) as $k=>$v){ // does not modify $array
echo str_replace('_',' ',$k)," : $v\n";
}
echo "\n";
}
Method #2:
echo "\n---\n";
foreach($array['value'] as $subarray){
unset($subarray['RowKey'],$subarray['Timestamp']); // does not modify $array
foreach($subarray as $k=>$v){
echo str_replace('_',' ',$k)," : $v\n";
}
echo "\n";
}
Output:
