PHP: Splitting Strings by Delimiters

When working with strings in PHP, the need to split them into smaller parts based on a specific delimiter often arises. In this context, the explode() function is a valuable tool, allowing you to achieve this task efficiently.

Question:

To split a string by a delimiter, such as a period or comma, how can this be accomplished in PHP?

Answer:

To split a string using the explode() function, follow these steps:

1. Identify the Delimiter: Determine the character or string that separates the components of the input string. In the example given, a period (.) is the delimiter.
2. Pass Arguments to explode(): Use the explode() function as follows:

$parts = explode('.', $string);

In this case, $parts will be assigned an array containing the split components of $string.

3. Assign Specific Parts (Optional): If desired, you can directly assign specific parts of the result to variables:

list($part1, $part2) = explode('.', $string);

This assigns the first part to $part1 and the second part to $part2.
