What are some methods for locating specific text within a textarea input in PHP?

When working with a textarea input in PHP, you may need to locate specific text within the input. One way to do this is by using the strpos() function, which searches for a specific substring within a string. Another method is to use regular expressions with the preg_match() function to search for patterns within the textarea input. These methods can help you efficiently locate and extract specific text from a textarea input in PHP. 

// Using strpos() to locate specific text within a textarea input
$textarea_input = $_POST['textarea_input'];
$specific_text = 'example';

if (strpos($textarea_input, $specific_text) !== false) {
    echo 'Specific text found in the textarea input!';
} else {
    echo 'Specific text not found in the textarea input.';
}

// Using preg_match() with regular expressions to locate specific text within a textarea input
$textarea_input = $_POST['textarea_input'];
$specific_text = '/example/';

if (preg_match($specific_text, $textarea_input)) {
    echo 'Specific text found in the textarea input!';
} else {
    echo 'Specific text not found in the textarea input.';
}
