CArray ( [0] => one,two [1] => three [2] => four )

DArray ( [0] => one [1] => two [2] => three [3] => four )

Step-by-Step Solution

Solution:

Step 1: Understand explode() with limit parameter
The third parameter limits the number of pieces. Here, limit=3 means maximum 3 parts.
Step 2: Apply limit to splitting
The string splits at first two commas: 'one', 'two', and the rest 'three,four' stays as last part.
Final Answer:
Array ( [0] => one [1] => two [2] => three,four ) -> Option A
Quick Check:
explode(',', string, 3) limits to 3 parts [OK]

Quick Trick: Limit splits into max parts; last part keeps rest [OK]
