Set End of Line Breakpoints Using PHP_EOL Constant in Array Data

We will create an array and then loop through the array and display each item in a new line by applying the PHP_EOL to insert a new line character at the end of the line.

<?php
$profile = array('Name'=>'Kevin', 'Occupation'=>'Programmer', 'Hobby'=>'Football');

    // Multiple lines by PHP_EOL
    reset( $profile );
    while ( list($key, $value) = each( $profile ) ){
    echo ("$key => $value" . PHP_EOL);
    }
?> 

Output:

Name => Kevin
Occupation => Programmer
Hobby => Football

Set End of Line Breakpoints Using PHP_EOL Constant in File Data

We will create two-string data and then use the PHP_EOL constant to insert a new line character at each string’s end before outputting the lines in a file.

<?php
    $text = 'Test one' . PHP_EOL;
    $text .= 'Test two' . PHP_EOL;
 
    $file = fopen('test_file.txt', 'w');
    fputs($file, $text);
    fclose($file);echo $text;
?> 

Output:

Test one
Test two
