Question

take this string as an example: “will see you in London tomorrow and Kent the day after tomorrow”.

How would I convert this to an associative array that contains the keywords as keys, whilst preferably missing out the common words, like this:

Array ( [tomorrow] => 2 [London] => 1 [Kent] => 1)

Any help greatly appreciated.

Answer 1

using a blacklist of words not to be included

$str = 'will see you in London tomorrow and Kent the day after tomorrow';
$skip_words = array( 'in', 'the', 'will', 'see', 'and', 'day', 'you', 'after' );
// get words in sentence that aren't to be skipped and count their values
$words = array_count_values( array_diff( explode( ' ', $str ), $skip_words ) );

print_r( $words );
