How to Split Product Names and Prices in PHP Using preg_match_all()

When working with raw product data, it’s common to encounter a single string containing product names and corresponding prices that are difficult to manage. For instance, suppose you have the following string:

Our goal is to break this string into separate product descriptions and their respective prices. This guide will guide you through using PHP, specifically the preg_match_all() function, to achieve this efficiently.

Understanding the Problem

The raw string contains multiple products each followed by a price, separated by a series of dots. For our purposes, we want to extract the following two components for each product:

Product description

Price

Example output should look like this:

Product: Galax RTX2060 1 Click 12GB OC

Price: 729

You may also want to structure it as an array, like so:

array[0] = "Galax RTX2060 1 Click 12GB OC"

array[1] = "729"

The Solution with preg_match_all()

To process the string, we can use PHP's preg_match_all() function along with a regex pattern that captures the product names and prices. Here is how you can implement this:

Step 1: Set Up the Input String

First, we define the input string that contains the product details.

Step 2: Create the Regular Expression Pattern

Next, we will create a regex pattern to match the product descriptions and prices. The pattern will look like this:

Step 3: Explain the Regular Expression

Let’s break down this regex pattern to understand what each part does:

**\s***: Matches any leading whitespace before the product name.

(.*?): Uses a non-greedy match to capture the product description.

**\s***: Matches optional whitespace following the product name.

.{3,}: Matches three or more consecutive dots (ellipses).

**\s***: Again, matches any whitespace before the price.

(\d+ (?:.\d+ )?): Captures the price, which can be an integer or a decimal.

Step 4: Execute preg_match_all()

Now we can use this pattern with preg_match_all() to extract both product names and prices into two separate arrays:

Step 5: Output the Results

When you run the above PHP code, you’ll get an output similar to this:

Conclusion

By using the preg_match_all() function with an appropriately designed regex, you can efficiently break down complex strings into manageable arrays of product information. This technique is not only useful for product data but can also be applied to various scenarios where structured parsing is required.

With these steps, you should now be able to manipulate product data strings with ease, improving the organization and readability of your application data.
