The feof() function in PHP is an inherent function that checks a file pointer for the end-of-file. It determines whether or not the “end-of-file” has been reached. If the size of the content of a file is not known ahead of time, the feof() method is used to loop over it.
Why feof () used in Reading file ?
If the end-of-file has been reached or an error has occurred, the feof() method returns True. Otherwise, False is returned.
Syntax:
feof( $file )
Parameters:
In PHP, the feof() method takes only one parameter, $file. The file to be examined for end-of-file is specified by this argument.
Return Value:
If the end of the file has been reached or an error has occurred, it returns TRUE. Otherwise, False is returned.
Errors And Exception:
If the supplied file reference is invalid, it enters an infinite loop since end-of-file does not return True.
If a connection opened by fsockopen() is not terminated by the server, the feof() function hangs.
Let’s take one Example:-
Below examples will explain the feof() function:
Example 1:- In the below program the file named “test.txt” contains only a single line of text which is “This file consists of only a single line.”.
Output:
Example 2:- In the below program the file named “test-test.txt” contains the following text.
This is the first line.
This is the second line.
This is the third line.
Destructuring is a convenient way of extracting multiple values from data stored in objects and Arrays. The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables.

This function is used to read a single line from a file. You can pass this function a file handle corresponding to an open file, and optional length.
Why fgets() used in Reading file?
It returns a line from a file pointer and terminates at a given length, end of file(EOF), or new line, whichever comes first.
The fgets() function is passed the file to read and the number of bytes to read as arguments, and it returns a string of length -1 bytes from the file indicated by the user.
If it fails, it returns False.
Syntax:-
fgets(file, length)
Parameters Used:
The fgets() function in PHP accepts two parameters.
file : It specifies the file from which characters have to be extracted.
length : It specifies the number of bytes to be read by the fgets() function. The default value is 1024 bytes.
Return Value : It returns a string of length -1 bytes from the user-specified file, or False if the operation fails.
Errors And Exceptions:-
Because it reads a single line at a time, the method isn’t designed for huge files, and reading a long file can take a long time.
If the fgets() method is called more than once, the buffer must be emptied.
Although the fgets() method returns the Boolean False, it frequently produces a non-Boolean result that evaluates to False.
Let’s take one Example:-
Suppose there is a file named “test.txt” which consists of :
This is the first line.
This is the second line.
This is the third line.
An exception is a generalization of the concept of an error to include any unexpected condition encountered during execution.
Exception Handling-
try
catch
finally
throw
How does the Javascript callback function work?
A callback function is a function (It can be any function Anonymous Function, Arrow Function) passed into another function as an argument, which is then invoked inside the outer function to complete some kind of routine or action.
Synchronous – It waits for each operation to complete, after that it executes the next operation.
Asynchronous – It never waits for each operation to complete, rather it executes all operations in the first GO only.
map ( ) Method in JavaScript
The map( ) method creates a new array with the results of calling a provided function on every element in the calling array. the map calls a provided callback function once for each element in an array, in order, and returns a new array from the results.
