Basic Usage

Detect Emoji

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->detectAll($input);

print_r($emoji);

The method returns an array with details about each emoji found in the string.

Array
(
  [0] => Array
    (
      [emoji] => 👨‍👩‍👦‍👦
      [short_name] => man-woman-boy-boy
      [num_points] => 7
      [points_hex] => Array
        (
          [0] => 1F468
          [1] => 200D
          [2] => 1F469
          [3] => 200D
          [4] => 1F466
          [5] => 200D
          [6] => 1F466
        )
      [hex_str] => 1F468-200D-1F469-200D-1F466-200D-1F466
      [skin_tone] =>
    )
  [1] => Array
    (
      [emoji] => 👍🏼
      [short_name] => +1
      [num_points] => 2
      [points_hex] => Array
        (
          [0] => 1F44D
          [1] => 1F3FC
        )

      [hex_str] => 1F44D-1F3FC
      [skin_tone] => skin-tone-3
    )
)

emoji - The emoji sequence found, as the original byte sequence. You can output this to show the original emoji.
short_name - The short name of the emoji, as defined by Slack's emoji data.
num_points - The number of unicode code points that this emoji is composed of.
points_hex - An array of each unicode code point that makes up this emoji. These are returned as hex strings. This will also include "invisible" characters such as the ZWJ character and skin tone modifiers.
hex_str - A list of all unicode code points in their hex form separated by hyphens. This string is present in the Slack emoji data array.
skin_tone - If a skin tone modifier was used in the emoji, this field indicates which skin tone, since the short_name will not include the skin tone.

Detect Emoji and return only one specific param

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->detectAllWIthSingleParam($input, aksafan\emoji\source\EmojiDetector::EMOJI);

print_r($emoji);

The method returns an array with details about each emoji found in the string.

Array
(
  [0] => Array
    (
      👨‍👩‍👦‍👦
    )
  [1] => Array
    (
      👍🏼
    )
)

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->detectAllWIthSingleParam($input, aksafan\emoji\source\EmojiDetector::SHORT_NAME);

print_r($emoji);

Array
(
  [0] => Array
    (
      man-woman-boy-boy
    )
  [1] => Array
    (
      +1
    )
)

Possible params:

aksafan\emoji\source\EmojiDetector::EMOJI - The emoji sequence found, as the original byte sequence. You can output this to show the original emoji.
aksafan\emoji\source\EmojiDetector::SHORT_NAME - The short name of the emoji, as defined by Slack's emoji data.
aksafan\emoji\source\EmojiDetector::NUM_POINTS - The number of unicode code points that this emoji is composed of.
aksafan\emoji\source\EmojiDetector::POINTS_HEX - An array of each unicode code point that makes up this emoji. These are returned as hex strings. This will also include "invisible" characters such as the ZWJ character and skin tone modifiers.
aksafan\emoji\source\EmojiDetector::HEX_STR - A list of all unicode code points in their hex form separated by hyphens. This string is present in the Slack emoji data array.
aksafan\emoji\source\EmojiDetector::SKIN_TONE - If a skin tone modifier was used in the emoji, this field indicates which skin tone, since the short_name will not include the skin tone.

Replace Emoji with given replacer

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->replaceEmojis($input); //Default replacer is ''
// "Hello  World "

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->replaceEmojis($input, '1');
// "Hello 1 World 1"

$input = "0️⃣5️⃣5️⃣0️⃣";
$emoji = Yii::$app->emojiDetector->replaceEmojis($input, '2');
// "2222"

Count Emojis in text

$input = "Hello 👍🏼 World 👨‍👩‍👦‍👦";
$emoji = Yii::$app->emojiDetector->countEmojis($input);
// 2

$input = "0️⃣5️⃣5️⃣0️⃣";
$emoji = Yii::$app->emojiDetector->countEmojis($input);
// 4

Test if a string is a single emoji

Since simply counting the number of unicode characters in a string does not tell you how many visible emoji are in the string, determining whether a single character is an emoji is more involved.

$emoji = Yii::$app->emojiDetector->isSingleEmoji('👨‍👩‍👦‍👦');
// true

$emoji =Yii::$app->emojiDetector->isSingleEmoji('Emoji with text 👨‍👩‍👦‍👦');
// false

$emoji =Yii::$app->emojiDetector->isSingleEmoji('😻🐈');
// false

Test if a string has one or more emoji

$emoji = Yii::$app->emojiDetector->isEmoji('👨‍👩‍👦‍👦');
// true

$emoji =Yii::$app->emojiDetector->isEmoji('Emoji with text 👨‍👩‍👦‍👦');
// true

$emoji =Yii::$app->emojiDetector->isEmoji('😻🐈');
// true

$emoji =Yii::$app->emojiDetector->isEmoji('Just text');
// false

Get Emojis' map

$emoji = Yii::$app->emojiDetector->getEmojiMap();

print_r($emoji);

The method returns an array of key-values pairs of emoji hex unicode and its short (friendly) name.

Array
(
  [0023-FE0F-20E3] => hash
  [002A-FE0F-20E3] => keycap_star
  [0030-FE0F-20E3] => zero
  [0031-FE0F-20E3] => one
  [0032-FE0F-20E3] => two
  [0033-FE0F-20E3] => three
  [0034-FE0F-20E3] => four
  [0035-FE0F-20E3] => five
  ...
  [2B55] => o
  [3030-FE0F] => wavy_dash
  [303D-FE0F] => part_alternation_mark
  [3297-FE0F] => congratulations
  [3299-FE0F] => secret
)

Get Emojis' regexp. The method returns a string with regexp (build on emojis' map) to detect emojis

$emoji = Yii::$app->emojiDetector->getEmojiRegexp();
// "/(?:\x{1F468}\x{200D}\x{2764}\x{FE0F}\x{200D}\x{1F48B}\x{200D}\x{1F468}|\x{1F469}\x{200D}\x{2764}\x{FE0F}\x{200D}\x{1F48B}\x{200D}\x{1F469}|\x{1F469}\x{200D}\x{2764}\x{FE0F}\x{200D}\x{1F48B}\x{200D}\x{1F468}|\x{1F3F4}\x{E0067}\x{E0062}\x{E0073}\x{E0063}\x{E0074}\x{E007F}|\x{1F3F4}\x{E0067}\x{E0062}\x{E0065}\x{E006E}\x{E0067}\x{E007F}|\x{1F3F4}\x{E0067}\x{E0062}\x{E0077}\x{E006C}\x{E0073}\x{E007F}...)"
