In what scenarios would it be advisable for PHP developers to use methods like explode() and fwrite() instead of fseek() for writing text to specific positions in files?

If a PHP developer needs to write text to specific positions in a file, it would be advisable to use methods like explode() and fwrite() instead of fseek() when the exact position is not known beforehand. This is because explode() can be used to split the file content into an array based on a delimiter, allowing for easy manipulation and insertion of text at specific positions. Then, fwrite() can be used to write the modified content back to the file.

$file = 'example.txt';
$content = file_get_contents($file);
$lines = explode("\n", $content);

// Insert text at specific position
$position = 2;
$newLine = "New line to insert\n";
array_splice($lines, $position, 0, $newLine);

// Write modified content back to file
$modifiedContent = implode("\n", $lines);
file_put_contents($file, $modifiedContent);
