How can PHP be used to search for a specific string in a file and extract content until a certain point?

To search for a specific string in a file and extract content until a certain point in PHP, you can read the file line by line, search for the specific string, and then continue reading until you reach the desired end point. This can be achieved by using functions like fopen(), fgets(), and strpos(). 

$file = fopen('example.txt', 'r');
$extractedContent = '';
$found = false;

while (($line = fgets($file)) !== false) {
    if (strpos($line, 'specific string') !== false) {
        $found = true;
    }

    if ($found) {
        $extractedContent .= $line;
        
        // Stop reading at the desired end point
        if (strpos($line, 'end point') !== false) {
            break;
        }
    }
}

fclose($file);

echo $extractedContent;
