PHP Clear Console

There is no specific built-in function in PHP to clear the console (command-line interface). The console output in PHP is typically meant for displaying results or debug information, and it’s not intended to be cleared like in a traditional terminal environment.

However, if you want to simulate a console-like behavior where the output appears as if it is being cleared and updated dynamically, you can achieve it using some PHP techniques.

Example 1: Simple Console-like Output

<?php
echo "Starting...\n";

// Sleep for 2 seconds to simulate a delay
sleep(2);

// Use backspace character \r to move the cursor to the beginning of the line
echo "Working...\r";

// Sleep again to simulate another delay
sleep(2);

// Final output
echo "Done!\n";
?>

In this example, we use the echo statement to print output. The backspace character (\r) is used to move the cursor back to the beginning of the line, creating an illusion of clearing the previous output. The output will appear as “Starting… Working… Done!” sequentially, with a delay of 2 seconds between each message.

Example 2: Using Escape Sequences

<?php
echo "Starting...\n";

// Sleep for 2 seconds
sleep(2);

// Use escape sequence \033[2J to clear the screen
echo "\033[2J"; // Clear screen

// Use escape sequence \033[H to move the cursor to the top left corner of the screen
echo "\033[H"; // Move cursor to top left corner

// Final output
echo "Done!\n";
?>

In this example, we use escape sequences to control the appearance of the console output. The escape sequence \033[2J clears the screen, and \033[H moves the cursor to the top left corner of the screen. This creates a visual effect similar to clearing the console. The output will appear as “Starting… Done!” with a 2-second delay before displaying “Done!”.
