PHP delimited strings are arrays
Explode
explode-using one string to split another string
Array explode (string $separator, string $string [, int $limit])
This function returns an array of strings, each of which is a substring of string, separated by the separator of the strings as the boundary points. If the limit parameter is set, the returned array contains a maximum of limit elements, and the last element will contain the remainder of the string.
If separator is an empty string (""), Explode () returns FALSE. If separator contains a value that is not found in a string, explode () returns an array containing a single element of string.
If the limit parameter is a negative number, all elements except the last-limit element are returned. This feature is new in PHP 5.1.0.
For historical reasons, although implode () can receive two parameter sequences, explode () does not work. You must ensure that the separator parameter is not preceded by a string parameter.
Note: Query columns can be written so when constructing SQL statements
$field = Explode (': ', ' * ');//Today we know explode this usage
