In an array, there are many elements in it. But in some operations, you might like to join all the elements within an array to become a string and use the string for other use, how can this be done?? There is a function of PHP can do the job, which is implode( ). Let me show how to do so:

First the implode( ) function take in 2 parameters:

1. The separator string between each elements, I use S to represent it.
2. The array. I use A to represent it.

So with the 2 parameters we get for implode( ):
implode(“S“, A);
The separator string S must be within a pair of ” .

Here is an example:

First, we create an array:

<?php 
$arrayOne[0] = "Hi";
$arrayOne[1] = "how";
$arrayOne[2] = "are";
$arrayOne[3] = "you";
$arrayOne[4] = "today";
?>

Now we use implode( ) to join them all together into a string and with a space between them. We create a PHP variable: $astring to store the new string.

<?php
$arrayOne[0] = "Hi";
$arrayOne[1] = "how";
$arrayOne[2] = "are";
$arrayOne[3] = "you";
$arrayOne[4] = "today";
 
$astring = implode(" ", $arrayOne );
?>

At last, we print out the string and see if everything goes correctly:

<?php
$arrayOne[0] = "Hi";
$arrayOne[0] = "how";
$arrayOne[0] = "are";
$arrayOne[0] = "you";
$arrayOne[0] = "today";
 
$astring = implode(" ", $arrayOne );
 
echo $astring;
?>

This should give us an output:
Hi how are you today
