Use the fs. readFileSync() method to read a text file into an array in JavaScript, e.g. const contents = readFileSync(filename, 'utf-8'). split('\n') . The method will return the contents of the file, which we can split on each newline character to get an array of strings.
In Java, we can store the content of the file into an array either by reading the file using a scanner or bufferedReader or FileReader or by using readAllLines method.
The general form for reading the data from an array is :Name of array [array index] ; Ex: marks[3] ; It can display the marks of 4th subject stored in the position 3.
If you plan on reusing those same values inside the array, you could use var_export on creating that array file instead.
Basic example:
$arr = array('name','rollno','address');
file_put_contents('array.txt', '<?php return ' . var_export($arr, true) . ';');
Then, when the time comes to use those values, just use include:
$my_arr = include 'array.txt';
echo $my_arr[0]; // name
Or just use a simple JSON string, then encode / decode:
$arr = array('name','rollno','address');
file_put_contents('array.txt', json_encode($arr));
Then, when you need it:
$my_arr = json_decode(file_get_contents('array.txt'), true);
echo $my_arr[1]; // rollno
Use this one:
$arr = file('array.txt', FILE_IGNORE_NEW_LINES);
print_r($arr);
