string implode(string $separator, array $parts)
(PHP 4, PHP 5)
| $separator | A string which is inserted between the individual parts to make a single string. |
|---|---|
| $parts | An array of strings which will be combined. |
| RETURNS | The combined parts from the array as a single string with the $separator between the parts. |
Implode converts an array of strings ($parts) into one single string by placing the $separator text between each of the parts. An array is ordered by its index in the case of a standard array.
If the $parts array has only one element, that element's string will be returned without any $separator. If the $parts array is empty, an empty string will be returned.
// compute the arc tangent for the angle 1.4 radians $options = array('apple', 'banana', cherry'); $pattern = implode('|', $options); echo 'Fruit Pattern = ' . $pattern; // outputs: "apple|banana|cherry"
