PHP – Implode

by Hiroshi on June 23rd, 2008

The PHP function implode operates on an array and is known as the “undo” function of explode. If you have used explode to break up a string into pieces or parts or just have an array of stuff you can use implode to put them all into one string.

PHP Implode – Combining Exploded Pieces

The first argument of implode is the string of characters you want to use to join the array pieces together. The second argument is the array (pieces).

<?php
$pieces = array("Hello", "World,", "I", "am", "Here!");
 
$WithSpaces = implode(" ", $pieces);
$WithDashes = implode("-", $pieces);
 
for($i = 0; $i < count($pieces); $i++)
{
	echo "Piece no $i = $pieces[$i] <br />";
}
 
echo "<br />";
 
echo "Combined With Spaces = $WithSpaces <br />";
echo "Combined With Dashes = $WithDashes";
?>

Result

Piece no 0 = Hello
Piece no 1 = World,
Piece no 2 = I
Piece no 3 = am
Piece no 4 = Here!
 
Combined With Spaces = Hello World, I am Here!
Combined With Dashes = Hello-World,-I-am-Here!
