How can regular expressions be effectively utilized in PHP to extract specific text sections between two strings in a file?

Regular expressions can be effectively utilized in PHP to extract specific text sections between two strings in a file by using the preg_match() function. This function allows you to define a pattern that matches the text you want to extract, along with the starting and ending delimiters. By using capturing groups in the regular expression pattern, you can extract the desired text section between the two strings. 

$file_contents = file_get_contents('example.txt');
$pattern = '/startDelimiter(.*?)endDelimiter/';
preg_match($pattern, $file_contents, $matches);
$extracted_text = $matches[1];
echo $extracted_text;
