Retrieving Data Line by Line from a Text File in PHP

If you encounter a scenario where you need to access data from a plaintext file line by line within your PHP application, there's a convenient and straightforward solution. Let's delve into how to achieve this with ease.

To begin, consider a text file located on your server containing a set of data arranged line by line. The goal is to read this data efficiently into your PHP script. Here's how you can accomplish this:

<code class="php">$fh = fopen('filename.txt','r');
while ($line = fgets($fh)) {
  // Perform operations or process each line here
}
fclose($fh);</code>

By utilizing the fopen function, you gain access to the file and open it for reading. The subsequent fgets function comes into play, allowing you to read each line of the file and store it in the $line variable. This process continues until the end of the file is reached.

As you iterate through each line, you can perform necessary operations or process the data within the loop. It's worth noting that the PHP manual provides important information regarding potential end-of-line issues that may arise for users running Mac operating systems. By taking note of these considerations, you can ensure seamless operation of your file reading script.
