Requires

• PHP 7.4 min.
• PHP-intl extension

Available lexers

• English
• French
• German

Usage

composer require ambroisemaupate/date-to-sentence

use AM\Date2Sentence\EnglishDateLexer;

$lexer = new EnglishDateLexer();

$lexer->setDates([
     new DateTime('2017-06-01'),
     new DateTime('2017-06-02'),
     new DateTime('2017-06-03'),
 ]);

echo $lexer->toSentence();
// "From June 1st to June 3rd"


$lexer->setDates([
     new DateTime('2017-06-01'),
     new DateTime('2017-06-02'),
     new DateTime('2017-06-03'),
     new DateTime('2017-06-10'),
 ]);

echo $lexer->toSentence();
// "From June 1st to June 3rd and June 10th"

With wrap option

use AM\Date2Sentence\EnglishDateLexer;

$nonContinuousLexer = new EnglishDateLexer([
    new DateTime('2017-06-01'),
    new DateTime('2017-06-02'),
    new DateTime('2017-06-03'),
    new DateTime('2017-06-10'),
], ['wrap_format' => '<span>%s</span>']);

echo $nonContinuousLexer->toSentence();
// "From <span>June 1st</span> to <span>June 3rd</span> and <span>June 10th</span>"

With French lexer

use AM\Date2Sentence\FrenchDateLexer;

$lexer = new FrenchDateLexer([
    new DateTime('2017-06-01'),
    new DateTime('2017-06-02'),
    new DateTime('2017-06-03'),
]);

echo $lexer->toSentence();
// "Du 1er au 3 juin"

$nonContinuousLexer = new FrenchDateLexer([
    new DateTime('2017-06-01'),
    new DateTime('2017-06-02'),
    new DateTime('2017-06-03'),
    new DateTime('2017-06-10'),
]);

echo $nonContinuousLexer->toSentence();
// "Du 1er au 3 juin et le 10 juin"

Setting tolerance

Set tolerance before dates to changes how days are listed. You can force from-to writing even if there are some missing days (e.g. weekends).

use AM\Date2Sentence\EnglishDateLexer;

$nonContinuousLexer = new EnglishDateLexer();
// Tolerate 1 missing day between dates.
$nonContinuousLexer->setTolerance(1);
$nonContinuousLexer->setDates([
    new DateTime('2017-06-01'),
    // no 2nd
    new DateTime('2017-06-03'),
    // no 4th
    new DateTime('2017-06-05'),
    // no 6th
    new DateTime('2017-06-07'),
]);

echo $nonContinuousLexer->toSentence();
// "From June 1st to June 7th"

Grouping by month

Date2Sentence is made to group days within the same month not to repeat same month-name over and over.

use AM\Date2Sentence\EnglishDateLexer;

$nonContinuousLexer = new EnglishDateLexer();
$nonContinuousLexer->setDates([
    new DateTime('2017-06-01'),
    // no 2nd
    new DateTime('2017-06-03'),
    // no 4th
    new DateTime('2017-06-05'),
    // no 6th
    new DateTime('2017-06-07'),
    new DateTime('2017-07-01'),
]);

echo $nonContinuousLexer->toSentence();
// "June 1st, 3rd, 5th, 7th and July 1st"

//
// In French, it works too…
// "Les 1er, 2, 5, 7 juin et le 1er juillet"

Get hours

Date2Sentence can also extract times from your given dates:

use AM\Date2Sentence\EnglishDateLexer;

$lexer = new EnglishDateLexer();
$lexer->setDates([
    new DateTime('2017-06-01 20:00:00'),
    new DateTime('2017-06-03 21:00:00'),
    new DateTime('2017-06-05 20:00:00'),
    new DateTime('2017-06-07 21:00:00'),
    new DateTime('2017-07-01 20:00:00'),
]);

echo json_encode(array_keys($this->getLexer()->getAvailableTimes()));
// [
//    "20:00",
//    "21:00"
// ]

Get dates as array

If you need to render manually you date groups, you can use generic toArray method which will group start and end dates into arrays. Dates in same array are continuous, separate arrays mean that they’re not continuous.

use AM\Date2Sentence\EnglishDateLexer;

$lexer = new EnglishDateLexer();
$lexer->setDates([
    new DateTime('2017-06-01 20:00:00'),
    new DateTime('2017-06-02 21:00:00'),
    new DateTime('2017-06-03 21:00:00'),
    new DateTime('2017-07-01 20:00:00'),
    new DateTime('2017-07-02 21:00:00'),
    new DateTime('2017-07-03 21:00:00'),
]);

echo json_encode($this->getLexer()->toArray());
// [
//    [
//        {"date":"2017-06-01 20:00:00.000000","timezone_type":3,"timezone":"Europe\/Paris"},
//        {"date":"2017-06-03 21:00:00.000000","timezone_type":3,"timezone":"Europe\/Paris"}
//    ],
//    [
//        {"date":"2017-07-01 20:00:00.000000","timezone_type":3,"timezone":"Europe\/Paris"},
//        {"date":"2017-07-03 21:00:00.000000","timezone_type":3,"timezone":"Europe\/Paris"}
//    ]
// ]

Get days of week

Date2Sentence can also extract days of week from your given dates, day will be represented as their number (1 for Monday, 7 for Sunday) and will be ordered:

use AM\Date2Sentence\EnglishDateLexer;

$lexer = new EnglishDateLexer();
$lexer->setDates([
    new DateTime('2017-06-01'),
    new DateTime('2017-06-02'),
    new DateTime('2017-06-03'),
    new DateTime('2017-06-08'),
    new DateTime('2017-06-08'),
]);

echo json_encode($this->getLexer()->getAvailableDaysOfWeek());
// [
//    4,
//    5,
//    6
// ]
