PHP `feof()`: Why Isn't My While Loop Printing the Entire File?

PHP: While Loop (feof()) Not Outputting Everything

In this issue, the user attempts to read and print the contents of a text file using a while loop and the feof() function. However, they encounter an incomplete output, especially towards the end of the file.

The issue arises from the placement of the feof() test. In the original code, feof() checks for the end of file before reading the last line, resulting in a truncated last line.

To resolve this, the code provided in the answer rewrites the loop condition to test feof() as part of the reading process:

while (($buffer = fgets($handle, 4096)) !== false) {

This ensures that the loop continues until the end of the file is reached and all lines are read and printed.

Additionally, the answer emphasizes the importance of error handling by removing the @ suppression operator from fopen() and including error handling to catch any file opening errors.

With these modifications, the loop correctly reads and displays the entire contents of the text file, including the last line.
