What is the best way to read specific data from a text file using PHP?

To read specific data from a text file using PHP, you can use file() function to read the file into an array line by line, then loop through the array to find the specific data you are looking for. Alternatively, you can use file_get_contents() function to read the entire file into a string and then use regular expressions or string manipulation functions to extract the specific data. 

// Read the text file into an array
$lines = file('data.txt');

// Loop through the array to find specific data
foreach ($lines as $line) {
    if (strpos($line, 'specific_data') !== false) {
        echo $line;
    }
}
