Error handling in PHP file operations
The simple most way of handling error in PHP while operating with file is function die().
Here is an example. If we fail to open the file a.txt then we can throw a message using the die() function.
$file = fopen("a.txt", "r") or die("The file cannot be opened.");
Here is another example. If the file a.txt does not exists then we throw an error message using function die().
if (file_exists("a.txt"))
{
$file = fopen("a.txt", "r");
}
else
{
die("The file does not exists.");
}
