How to Read and Write Tournament Match Results in PHP

Managing sports tournament data can be tricky, especially when you need to track match results, points, and rankings for multiple teams. In this article, we will explore how to efficiently read and write tournament match results using PHP, specifically in the context of football (soccer) tournaments such as the Champions League.

The Problem: Keeping Track of Match Results

Consider a scenario where you have results from various matches in a football tournament, and you want to maintain a clear and organized point ranking for each team. Here's an example of match results you might encounter:

From these results, you need to calculate the points, wins, draws, and losses for each team. Points are awarded as follows:

Win: 3 points

Draw: 1 point

Loss: 0 points

Additionally, you want to present the final standings ordered by points, and alphabetically in case of ties.

The Solution: A PHP Script to Process Tournament Data

Step 1: Reading Data from a File

The first step is to read the match results from a text file. You can do this using PHP's file() function, which retrieves the contents of a file into an array, with each line as an element of the array.

Step 2: Processing Results

Next, we will loop through each line of results, splitting the line into its respective parts: the two teams and the match outcome. This is done using explode().

Step 3: Storing Match Outcomes

To keep track of each team's outcomes, we will initialize an array that represents each team and its match results. For each match, we record wins, losses, and draws.

Note: initializeTeam() is a function you'd create to set the initial data for a team, and recordMatchOutcome() would handle adding results based on the scores.

Step 4: Calculating Points and Rankings

After populating the teamList array with all match results, you will need to calculate points for each team based on their wins, draws, and losses.

Step 5: Writing the Results to a File

Finally, we will present the results in a user-friendly format, generating a table that can be saved into a file or displayed on a webpage.
