What are the advantages of using the strpos() function in PHP to search for specific words in a file?
When working with files in PHP, you may need to search for specific words or strings within the file content. One way to do this is by using the strpos() function, which allows you to find the position of a substring within a string. This can be useful for tasks such as parsing text files, extracting data, or performing text-based searches.
<?php
$file = 'example.txt';
$searchWord = 'specific word';
$content = file_get_contents($file);
$position = strpos($content, $searchWord);
if ($position !== false) {
echo "The word '$searchWord' was found at position $position in the file.";
} else {
echo "The word '$searchWord' was not found in the file.";
}
?>
