Method 2: Using Regular Expressions
Regular expressions offer more flexibility in handling different word patterns and can help clean the data by removing unwanted characters. This example uses preg_replace() function to remove non-word characters and converts all words to lowercase for case-insensitive counting.
PHP
<?php $fileContent = file_get_contents('gfg.txt'); // Remove non-word characters $fileContent = preg_replace('/[^\w\s]/', '', $fileContent); // Convert to lowercase for case-insensitive counting $words = str_word_count(strtolower($fileContent), 1); $wordCounts = array_count_values($words); foreach ($wordCounts as $word => $count) { echo "$word: $count\n"; } ?> |
