A better approach would maybe be to keep your values as keys in an associative array, and then call <code>array_keys()</code> on it when you want to actual array. That way you don't need to use <code>array_search</code> to find your element.

Use <a href="http://php.net/array_search" rel="noreferrer"><code>array_search</code></a> to get the key and remove it with <a href="http://php.net/unset" rel="noreferrer"><code>unset</code></a> if found:

<pre><code>if (($key = array_search('strawberry', $array)) !== false) {
 unset($array[$key]);
}
</code></pre>

<code>array_search</code> returns false (null until PHP 4.2.0) if no item has been found.

And if there can be multiple items with the same value, you can use <a href="http://php.net/array_keys" rel="noreferrer"><code>array_keys</code></a> to get the keys to all items:

<pre><code>foreach (array_keys($array, 'strawberry') as $key) {

Using <a href="http://www.php.net/manual/en/function.array-search.php" rel="nofollow"><code>array_seach()</code></a>, try the following:

<pre><code>if(($key = array_search($del_val, $messages)) !== false) {
 unset($messages[$key]);
}
</code></pre>

<code>array_search()</code> returns the key of the element it finds, which can be used to remove that element from the original array using <code>unset()</code>. It will return <code>FALSE</code> on failure, however it can return a "falsey" value on success (your key may be <code>0</code> for example), which is why the strict comparison <code>!==</code> operator is used.

The <code>if()</code> statement will check whether <code>array_search()</code> returned a value, and will only perform an action if it did.

I would prefer to use array_key_exists to search for keys in arrays like: 

<code>Array([0]=&gt;'A',[1]=&gt;'B',['key'=&gt;'value'])</code> 

to find the specified effectively, since array_search and in_array() don't work here. And do removing stuff with unset().

I think it will help someone.

If you are using a plain array here (which seems like the case), you should be using this code instead:

<pre><code>if (($key = array_search('strawberry', $array)) !== false) {
 array_splice($array, $key, 1);
}
</code></pre>

<code>unset($array[$key])</code> only removes the element but does not reorder the plain array.

Supposingly we have an array and use array_splice:

<pre><code>$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
array_splice($array, 2, 1);
json_encode($array); 
// yields the array ['apple', 'orange', 'blueberry', 'kiwi']
</code></pre>

Compared to unset:

<pre><code>$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
unset($array[2]);
json_encode($array);
// yields an object {"0": "apple", "1": "orange", "3": "blueberry", "4": "kiwi"}
</code></pre>

Notice how <code>unset($array[$key])</code> does not reorder the array.

 foreach ($array as $key =&gt; $value){
 if ($value == $del_val) {

 }
 }
 }
 return array_values($array);

</code></pre>

You can input an array or only a string with the element(s) which should be removed.
Write it like this:

<pre><code>$detils = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
$detils = array_delete(array('orange', 'apple'), $detils);
</code></pre>

OR

<code>$detils = array_delete('orange', $detils);</code>

It'll also reindex it.

The answer to <a href="https://stackoverflow.com/questions/7225070/php-array-delete-by-value-not-key">PHP array delete by value (not key)</a>
Given by 
 <a href="https://stackoverflow.com/users/924109/rok-kralj" title="rok-kralj">https://stackoverflow.com/users/924109/rok-kralj</a> 

IMO is the best answer as it removes and does not mutate 

<pre><code>array_diff( [312, 401, 15, 401, 3], [401] ) // removing 401 returns [312, 15, 3]
</code></pre>

It generalizes nicely, you can remove as many elements as you like at the same time, if you want.

Disclaimer: Note that my solution produces a new copy of the array while keeping the old one intact in contrast to the accepted answer which mutates. It might be a bit slower because of this.

This question has several answers but I want to add something more because when I used <code>unset</code> or <code>array_diff</code> I had several problems to play with the indexes of the new array when the specific element was removed (because the initial index are saved)

I get back to the example :

<pre><code>$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
$array_without_strawberries = array_diff($array, array('strawberry'));
</code></pre>

or

<pre><code>$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
unset($array[array_search('strawberry', $array)]);
</code></pre>

If you print the result you will obtain :

<pre><code>foreach ($array_without_strawberries as $data) {
 print_r($data);
}
</code></pre>

Result :

<pre><code>&gt; apple
&gt; orange
&gt; blueberry
&gt; kiwi
</code></pre>

But the indexes will be saved and so you will access to your element like :

<pre><code>$array_without_strawberries[0] &gt; apple
$array_without_strawberries[1] &gt; orange
$array_without_strawberries[3] &gt; blueberry
$array_without_strawberries[4] &gt; kiwi
</code></pre>

And so the final array are not re-indexed. So you need to add after the <code>unset</code> or <code>array_diff</code>:

<pre><code>$array_without_strawberries = array_values($array);
</code></pre>

After that your array will have a normal index :

<pre><code>$array_without_strawberries[0] &gt; apple
$array_without_strawberries[1] &gt; orange
$array_without_strawberries[2] &gt; blueberry
$array_without_strawberries[3] &gt; kiwi
</code></pre>

entityMap|blocks|key|36g83|text|我正在寻找同样问题的答案，偶然发现了这个话题。我认为主要有两种方式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6fhno|&|6lgt6|和使用|1h0qq|..。乍一看，第一种方法似乎更快，因为它不需要创建额外的数组(就像使用|14t1m|)。但我写了一个小的基准测试，并确保第二种方法不仅更简洁，而且更快！很高兴与你分享这一点。:)|6o0q4|https://glot.io/snippets/f6ow6biaol^0|0|0|0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|M|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|N|9|@]|A|@]|B|$]]|$2|E|4|F|6|7|8|O|9|@]|A|@]|B|$]]|$2|G|4|H|6|7|8|P|9|@]|A|@]|B|$]]|$2|I|4|J|6|7|8|Q|9|@]|A|@]|B|$]]|$2|K|4|L|6|7|8|R|9|@]|A|@]|B|$]]]]

I was looking for the answer to the same question and came across this topic. I see two main ways: the combination of <code>array_search</code> &amp; <code>unset</code> and the use of <code>array_diff</code>. At first glance, it seemed to me that the first method would be faster, since does not require the creation of an additional array (as when using <code>array_diff</code>). But I wrote a small benchmark and made sure that the second method is not only more concise, but also faster! Glad to share this with you. :)

Just u can do single line .it will be remove element from array

Use this simple way hope it will helpful

 if($value == 'strawberry')
 {
 unset($array[$k]);
 }
 }
</code></pre>

You can Try this
<pre><code>&lt;?php

$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');

$key = in_array(&quot;strawberry&quot;,$array);

if ($key) {
 
 unset($array[$key]);
 
}

?&gt;
</code></pre>

How do I remove an element from an array when I know the element's value? for example:
I have an array:
<pre><code>$array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');
</code></pre>
the user enters <code>strawberry</code>
<code>strawberry</code> is removed from <code>$array</code>.
To fully explain:
I have a database that stores a list of items separated by a comma. The code pulls in the list based on a user choice where that choice is located. So, if they choose strawberry they code pulls in every entry were strawberry is located then converts that to an array using split(). I want to them remove the user chosen items, for this example strawberry, from the array.
