Remove particular elements from an array using php : <p>I have one array like below</p>

<pre><code>Array
    (
        [AllocationPool] =&gt; TEST do not USE
        [Quarter] =&gt; 2016-Q4
        [Segment] =&gt; Storage
        [Region] =&gt; 
        [SubRegion] =&gt; 
        [Country] =&gt; 
        [typeofrec] =&gt; 0
        [TotalAllocations] =&gt; 100
        [TotalTransfersOut] =&gt; 75
        [TotalTransfersIn] =&gt; 0
        [StartOfAllocation] =&gt; 25
        [ApprovedActivities] =&gt; 0
        [AvailableBalance] =&gt; 25
        [TotalApprovedClaims] =&gt; 0
