Reading Plain Text Files in PHP

Question: How can we read every line of data from a plain text file in a PHP script?

Answer:

To effectively read a text file line by line in PHP, we utilize the fgets() function. Here's a detailed code snippet that demonstrates the process:

<code class="php">$fh = fopen('filename.txt', 'r');
while ($line = fgets($fh)) {
  // Here, you can manipulate the read line as needed.
  // For example, you could echo it or perform further processing.
  // echo($line);
}
fclose($fh);</code>

This code initializes a file pointer, $fh, to open the text file named 'filename.txt' in read mode. The while loop iteratively reads each line into the $line variable until the end of the file is reached, as indicated by the return value of fgets() becoming false. Within the loop, you have the flexibility to perform desired operations on each line.

However, it's important to note the potential for end-of-line issues when working with files created on different operating systems. Consult the PHP documentation on fgets() for further information and considerations when dealing with line endings.
