String split and explode in PHP - Mini Project: Build & Apply

String split and explode

📖 Scenario: You work in a small bakery. You have a list of ingredients for a cake stored as one string, separated by commas. You want to split this string into individual ingredients to handle them separately.

🎯 Goal: Learn how to use PHP's explode function to split a string into an array of parts based on a separator.

📋 What You'll Learn

Create a string variable with exact ingredients separated by commas

Create a separator variable with the comma character

Use explode with the separator and string to split into an array

Print the resulting array using print_r

💡 Why This Matters

🌍 Real World

Splitting strings is common when handling lists of items stored as text, like ingredients, tags, or CSV data.

💼 Career

Understanding string splitting helps in data processing, web development, and working with user input or files.

1

Create the ingredients string

Create a string variable called ingredients with the exact value "flour,sugar,butter,eggs,vanilla".

PHP

# Your code here

Need a hint?

Use double quotes to create the string with commas separating the ingredients.

2

Create the separator variable

Create a string variable called separator and set it to the comma character ",".

PHP

<?php
$ingredients = "flour,sugar,butter,eggs,vanilla";
# Your code here

Need a hint?

The separator is a string with just a comma inside quotes.

3

Split the string into an array

Use the explode function with $separator and $ingredients to create an array called ingredientList.

PHP

<?php
$ingredients = "flour,sugar,butter,eggs,vanilla";
$separator = ",";
# Your code here

Need a hint?

Call explode with the separator first, then the string.

4

Print the array of ingredients

Print the array ingredientList using print_r to show the split ingredients.

PHP

<?php
$ingredients = "flour,sugar,butter,eggs,vanilla";
$separator = ",";
$ingredientList = explode($separator, $ingredients);
# Your code here

Need a hint?

Use print_r($ingredientList); to display the array in a readable format.
