What are some best practices for handling tab characters and string manipulation in PHP when parsing data from a text file?

When parsing data from a text file in PHP, it's important to properly handle tab characters to ensure accurate string manipulation. One common approach is to use the PHP function `explode()` with the tab character '\t' as the delimiter to split the string into an array of values. This allows you to access individual data elements easily. Additionally, you can use `trim()` function to remove any leading or trailing whitespace, including tabs, from the parsed strings. 

// Example code snippet for parsing tab-delimited data from a text file
$filename = 'data.txt';
$file = fopen($filename, 'r');

while (!feof($file)) {
    $line = fgets($file);
    $data = explode("\t", $line);
    
    // Access individual data elements
    $firstElement = trim($data[0]);
    $secondElement = trim($data[1]);
    
    // Process the data as needed
    // ...
}

fclose($file);
