Array explode (string $separator, string $string [, int $limit])
The function has 3 parameters, and the first parameter $separator sets a split character (string). The second parameter $string specifies the string to manipulate. The $limit parameter is optional, specifying the maximum number of substrings to be split into.This function returns an array of separated substrings.
Look at the example below to analyze a comma-delimited line of text data.
