The following post provides 10+ File Handling Problems in PHP. Also, their solutions are available on respective links.

To begin with, write a PHP script to read the contents of a file and display them on the screen.

<?php
$filename = "file.txt";
$file = fopen($filename, "r");
echo fread($file, filesize($filename));
fclose($file);
?>

After that, write a PHP script to write a string to a file.

<?php
$filename = "file.txt";
$file = fopen($filename, "w");
fwrite($file, "Hello World!");
fclose($file);
?>

Then, write a PHP script to append a string to a file.

<?php
$filename = "file.txt";
$file = fopen($filename, "a");
fwrite($file, "Hello World Again!");
fclose($file);
?>

Next, write a PHP script to check if a file exists.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  echo "File exists!";
} else {
  echo "File does not exist!";
}
?>

Also, write a PHP script to check if a file is readable.

<?php
$filename = "file.txt";
if(is_readable($filename)){
  echo "File is readable!";
} else {
  echo "File is not readable!";
}
?>

Similarly, write a PHP script to check if a file is writable.

<?php
$filename = "file.txt";
if(is_writable($filename)){
  echo "File is writable!";
} else {
  echo "File is not writable!";
}
?>

Also, write a PHP script to delete a file.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  unlink($filename);
  echo "File deleted!";
} else {
  echo "File does not exist!";
}
?>

Write a PHP script to copy a file.

<?php
$filename = "file.txt";
$newfilename = "file_copy.txt";
if(file_exists($filename)){
  copy($filename, $newfilename);
  echo "File copied!";
} else {
  echo "File does not exist!";
}
?>

Further, write a PHP script to rename a file.

<?php
$filename = "file.txt";
$newfilename = "new_file.txt";
if(file_exists($filename)){
  rename($filename, $newfilename);
  echo "File renamed!";
} else {
  echo "File does not exist!";
}
?>

Likewise, write a PHP script to get the file size.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  echo "File size: " . filesize($filename) . " bytes.";
} else {
  echo "File does not exist!";
}
?>

Write a PHP script to get the file extension.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  echo "File extension: " . pathinfo($filename, PATHINFO_EXTENSION);
} else {
  echo "File does not exist!";
}
?>

Also, write a PHP script to get the file name.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  echo "File name: " . basename($filename);
} else {
  echo "File does not exist!";
}
?>

Lastly, write a PHP script to get the file path.

<?php
$filename = "file.txt";
if(file_exists($filename)){
  echo "File path: " . realpath($filename);
} else {
  echo "File does not exist!";
}
?>
