You don't want to convert the array to a string, you want to get the value of the array's sole element, if I read it correctly.

<pre><code>&lt;?php
 $foo = array( 18 =&gt; 'Something' );
 $value = array_shift( $foo );
 echo $value; // 'Something'.

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

Using array_shift you don't have to worry about the index.

EDIT: Mind you, array_shift is not the only function that will return a single value. array_pop( ), current( ), end( ), reset( ), they will all return that one single element. All of the posted solutions work. Using array shift though, you can be sure that you'll only ever get the first value of the array, even when there are multiple.

Yes there is. <a href="http://php.net/manual/en/function.serialize.php"><code>serialize()</code></a>. It can convert various data types (including object and arrays) into a string representation which you can <a href="http://www.php.net/manual/en/function.unserialize.php"><code>unserialize()</code></a> at a later time. Serializing an associative array such as <code>Array(18 =&gt; 'Somthing')</code> will preserve both keys and values:

<pre><code>&lt;?php

echo serialize($a); // a:1:{i:18;s:9:"Something";}
var_dump(unserialize('a:1:{i:18;s:9:"Something";}')); // array(1) {

If your goal is output your array to a string for debbuging: you can use the <a href="http://www.php.net/manual/en/function.print-r.php" rel="noreferrer">print_r()</a> function, which receives an expression parameter (your array), and an optional boolean return parameter. Normally the function is used to echo the array, but if you set the return parameter as true, it will return the array impression.

Example:

<pre><code> //We create a 2-dimension Array as an example
 $ProductsArray = array();

 $row_array['Qty'] = 20;
 $row_array['Product'] = "Cars";

 array_push($ProductsArray,$row_array);

 $row_array2['Qty'] = 30;
 $row_array2['Product'] = "Wheels";

 array_push($ProductsArray,$row_array2);

 //We save the Array impression into a variable using the print_r function
 $ArrayString = print_r($ProductsArray, 1);

 //You can echo the string
 echo $ArrayString;

 //or Log the string into a Log file
 $date = date("Y-m-d H:i:s", time());
 $LogFile = "Log.txt";
 $fh = fopen($LogFile, 'a') or die("can't open file");
 $stringData = "--".$date."\n".$ArrayString."\n";
 fwrite($fh, $stringData);
 fclose($fh);
</code></pre>

This will be the output:

<pre><code>Array
(
 [0] =&gt; Array
 (
 [Qty] =&gt; 20
 [Product] =&gt; Cars
 )

 [1] =&gt; Array
 (
 [Qty] =&gt; 30
 [Product] =&gt; Wheels
 )

)

 if (is_array($var)) {
 $toImplode = array();
 foreach ($var as $key =&gt; $value) {

 }
 $code = 'array('.implode(',', $toImplode).')';
 if ($return) return $code;
 else echo $code;
 } else {
 return var_export($var, $return);

A <code>For()</code> loop is very useful. You can add your array's value to another variable like this:

<pre><code>&lt;?php
 $dizi=array('mother','father','child'); //This is array

 $sayi=count($dizi);
 for ($i=0; $i&lt;$sayi; $i++) {
 $dizin.=("'$dizi[$i]',"); //Now it is string...
 }
 echo substr($dizin,0,-1); //Write it like string :D
?&gt;
</code></pre>

In this code we added $dizi's values and comma to $dizin:

<code>$dizin.=("'$dizi[$i]',");</code>

Now

<pre><code>$dizin = 'mother', 'father', 'child',
</code></pre>

It's a string, but it has an extra comma :)

And then we deleted the last comma, <code>substr($dizin, 0, -1);</code>

Output:

<blockquote>
 'mother','father','child'

Use the inbuilt function in PHP, <code>implode(array, separator)</code>:

<pre><code>&lt;?php
 $ar = array("parth","raja","nikhar");
 echo implode($ar,"/");
?&gt;
</code></pre>

Result: parth/raja/nikhar

For completeness and simplicity sake, the following should be fine:

<pre><code>$str = var_export($array, true);
</code></pre>

It does the job quite well in my case, but others seem to have issues with whitespace. In that case, the answer from <code>ucefkh</code> provides a workaround from a comment in the PHP manual.

I have a PHP array and want to convert it to a string. 

I know I can use <code>join</code> or <code>implode</code>, but in my case array has only one item. Why do I have to use combine values in an array with only one item?

This array is the output of my PHP function which returns an array:

<pre><code>Array(18 =&gt; 'Something');
</code></pre>

How do I convert this to a string?

我有一个PHP数组，并希望将其转换为字符串。我知道我可以使用join或implode，但在我的例子中，数组只有一项。为什么我必须在一个只有一项的数组中使用组合值？这个数组是我的PHP函数的输出，它返回一个数组：Array(18 => 'Something');如何将其转换为字符串？
