Remove new lines from string in PHP

Given a multiple line sentence or statement the task is to convert the whole statement in a
single line. See the example below.

Examples:

Input : Hello
        welcome to geeksforgeeks.
Output : Hello welcome to geeksforgeeks.
Remove the new line between Hello and geeksforgeeks.

Input : I
        love
        geeksforgeeks
Output : I love geeksforgeeks

The idea is to use str_replace()

<?php
$text = "Hello \nwelcome to \ngeeksforgeeks";
echo $text;

echo "\n";
$text = str_replace("\n", "", $text);
echo $text;
?>
