Reading Plain Text Files with PHP

Question:

You have a plain text file with lines of data on a server. How can you read all the information from the file line by line using PHP?

Answer:

To read a plain text file line by line with PHP, follow these steps:

<code class="php">$fh = fopen('filename.txt','r');
while ($line = fgets($fh)) {
  // Perform any necessary operations with the line
  // For example, echo $line;
}
fclose($fh);</code>

In this code, fopen() opens the file and returns a file handler. The while loop then reads each line from the file using fgets() and places it in the $line variable. You can perform any necessary actions with each line within the loop. After reading all the lines, fclose() closes the file.

Note: As mentioned in the provided answer, be aware of potential end of line issues with Macs when using fgets(). See the PHP manual for more details.
