Assume we have the following array:

<pre><code> $stockonhand = array( "large green", "small blue", "xlarge brown", "large green", "medieum yellow", "xlarge brown", "large green");
</code></pre>

1) Copy and paste this function once on top your page.

<pre><code> function arraycount($array, $value){
 $counter = 0;
 foreach($array as $thisvalue) /*go through every value in the array*/
 {
 if($thisvalue === $value){ /*if this one value of the array is equal to the value we are checking*/
 $counter++; /*increase the count by 1*/
 }
 }
 return $counter;
 }
</code></pre>

2) All what you need to do next is to apply the function every time you want to count any particular value in any array. For example:

<pre><code> echo arraycount($stockonhand, "large green"); /*will return 3*/

 echo arraycount($stockonhand, "xlarge brown"); /*will return 2*/
</code></pre>

blocks|key|904833|text|从PHP5.4.0开始，您可以对由array_count_values()生成的数组的索引[6]使用函数数组取消引用|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|904834|$instances+=+array_count_values($array)[6];|code-block|syntax|javascript|904835|因此，如果找不到，则检查并分配0：|904836|$instances+=+array_count_values($array)[6]+??+0;|904837|entityMap^0|H|K|19|3|0|0|F|1|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|V|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

As of PHP 5.4.0 you can use function array dereferencing for the index <code>[6]</code> of the array resulting from <code>array_count_values()</code>:
<pre><code>$instances = array_count_values($array)[6];
</code></pre>
So to check and assign <code>0</code> if not found:
<pre><code>$instances = array_count_values($array)[6] ?? 0;
</code></pre>

blocks|key|688413|text|这正是你要找的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|688414|<?php

This is exactly what you looking for 

<pre><code>&lt;?php
 $MainString = 'Yellow Green Orange Blue Yellow Black White Purple';
 $FinderString = 'Yellow Blue White';
 $mainArray = explode(" ", $MainString);
 $findingArray = explode(" ", $FinderString);
 $count = 0;
 $eachtotal = array_count_values($mainArray);
 foreach($findingArray as $find){

 $count += $eachtotal[$find];
 }
 echo $count;

I am trying to find a native PHP function that will allow me to count the number of occurrences of a particular value in an array. I am familiar with the array_count_values() function, but that returns the count of all values in an array. Is there a function that allows you to pass the value and just return the instance count for that particular value? For example:

<pre><code>$array = array(1, 2, 3, 3, 3, 4, 4, 5, 6, 6, 6, 6, 7);

$instances = some_native_function(6, $array); //$instances will be equal to 4
</code></pre>

I know how to create my own function, but why re-invent the wheel?

我正在尝试寻找一个原生PHP函数，它允许我计算数组中特定值出现的次数。我熟悉array_count_values()函数，但它返回数组中所有值的计数。是否有一个函数允许您传递该值并只返回该特定值的实例计数？例如：$array = array(1, 2, 3, 3, 3, 4, 4, 5, 6, 6, 6, 6, 7);...
