implode — Creates a string from array elements.


string implode(glue, pieces);
string glue: String to put between the pieces
array pieces: Array to implode




implode() creates a string from an array's values. The string consists of each value in the pieces array, with the string specified in the glue argument placed between each piece. The values occur in the string in the same order as in the array.

To split a string into an array of substrings:





Example 1204. Illustrate the use of implode()

$pieces = array('piece one', 'piece two', 'piece three' );
$glue   = '[glue]';

echo "The structure of the \$pieces array is:\n";

echo "\nCalling \"echo implode('$glue', \$pieces);\" outputs:\n";
echo implode($glue, $pieces);

The structure of the $pieces array is:
array(3) {
  string(9) "piece one"
  string(9) "piece two"
  string(11) "piece three"

Calling "echo implode('[glue]', $pieces);" outputs:
piece one[glue]piece two[glue]piece three
