我有一个检查字符串是否为表情符号的函数。 function
:
function has_emojis( $string ) {
preg_match( '/[\x{1F600}-\x{1F64F}]/u', $string, $matches_emo );
return !empty( $matches_emo[0] ) ? true : false;
}
问题: 它无法识别所有表情符号,例如,将其重新定义为表情符号,但不能识别此表情符号(还有更多)
我尝试更改preg_match范围,但未成功,因为我不知道所有表情符号的具体范围。
使用此功能:
function has_emojis( $string ) {
// Array of emoji (v12, 2019) unicodes from https://unicode.org/emoji/charts/emoji-list.html
$unicodes = array( '1F600','1F603','1F604','1F601','1F606','1F605','1F923','1F602','1F642','1F643','1F609','1F60A','1F607','1F970','1F60D','1F929','1F618','1F617','263A','1F61A','1F619','1F60B','1F61B','1F61C','1F92A','1F61D','1F911','1F917','1F92D','1F92B','1F914','1F910','1F928','1F610','1F611','1F636','1F60F','1F612','1F644','1F62C','1F925','1F60C','1F614','1F62A','1F924','1F634','1F637','1F912','1F915','1F922','1F92E','1F927','1F975','1F976','1F974','1F635','1F92F','1F920','1F973','1F60E','1F913','1F9D0','1F615','1F61F','1F641','2639','1F62E','1F62F','1F632','1F633','1F97A','1F626','1F627','1F628','1F630','1F625','1F622','1F62D','1F631','1F616','1F623','1F61E','1F613','1F629','1F62B','1F971','1F624','1F621','1F620','1F92C','1F608','1F47F','1F480','2620','1F4A9','1F921','1F479','1F47A','1F47B','1F47D','1F47E','1F916','1F63A','1F638','1F639','1F63B','1F63C','1F63D','1F640','1F63F','1F63E','1F648','1F649','1F64A','1F48B','1F48C','1F498','1F49D','1F496','1F497','1F493','1F49E','1F495','1F49F','2763','1F494','2764','1F9E1','1F49B','1F49A','1F499','1F49C','1F90E','1F5A4','1F90D','1F4AF','1F4A2','1F4A5','1F4AB','1F4A6','1F4A8','1F573','1F4A3','1F4AC','1F441','FE0F','200D','1F5E8','FE0F','1F5E8','1F5EF','1F4AD','1F4A4','1F44B','1F91A','1F590','270B','1F596','1F44C','1F90F','270C','1F91E','1F91F','1F918','1F919','1F448','1F449','1F446','1F595','1F447','261D','1F44D','1F44E','270A','1F44A','1F91B','1F91C','1F44F','1F64C','1F450','1F932','1F91D','1F64F','270D','1F485','1F933','1F4AA','1F9BE','1F9BF','1F9B5','1F9B6','1F442','1F9BB','1F443','1F9E0','1F9B7','1F9B4','1F440','1F441','1F445','1F444','1F476','1F9D2','1F466','1F467','1F9D1','1F471','1F468','1F9D4','1F471','200D','2642','FE0F','1F468','200D','1F9B0','1F468','200D','1F9B1','1F468','200D','1F9B3','1F468','200D','1F9B2','1F469','1F471','200D','2640','FE0F','1F469','200D','1F9B0','1F469','200D','1F9B1','1F469','200D','1F9B3','1F469','200D','1F9B2','1F9D3','1F474','1F475','1F64D','1F64D','200D','2642','FE0F','1F64D','200D','2640','FE0F','1F64E','1F64E','200D','2642','FE0F','1F64E','200D','2640','FE0F','1F645','1F645','200D','2642','FE0F','1F645','200D','2640','FE0F','1F646','1F646','200D','2642','FE0F','1F646','200D','2640','FE0F','1F481','1F481','200D','2642','FE0F','1F481','200D','2640','FE0F','1F64B','1F64B','200D','2642','FE0F','1F64B','200D','2640','FE0F','1F9CF','1F9CF','200D','2642','FE0F','1F9CF','200D','2640','FE0F','1F647','1F647','200D','2642','FE0F','1F647','200D','2640','FE0F','1F926','1F926','200D','2642','FE0F','1F926','200D','2640','FE0F','1F937','1F937','200D','2642','FE0F','1F937','200D','2640','FE0F','1F468','200D','2695','FE0F','1F469','200D','2695','FE0F','1F468','200D','1F393','1F469','200D','1F393','1F468','200D','1F3EB','1F469','200D','1F3EB','1F468','200D','2696','FE0F','1F469','200D','2696','FE0F','1F468','200D','1F33E','1F469','200D','1F33E','1F468','200D','1F373','1F469','200D','1F373','1F468','200D','1F527','1F469','200D','1F527','1F468','200D','1F3ED','1F469','200D','1F3ED','1F468','200D','1F4BC','1F469','200D','1F4BC','1F468','200D','1F52C','1F469','200D','1F52C','1F468','200D','1F4BB','1F469','200D','1F4BB','1F468','200D','1F3A4','1F469','200D','1F3A4','1F468','200D','1F3A8','1F469','200D','1F3A8','1F468','200D','2708','FE0F','1F469','200D','2708','FE0F','1F468','200D','1F680','1F469','200D','1F680','1F468','200D','1F692','1F469','200D','1F692','1F46E','1F46E','200D','2642','FE0F','1F46E','200D','2640','FE0F','1F575','1F575','FE0F','200D','2642','FE0F','1F575','FE0F','200D','2640','FE0F','1F482','1F482','200D','2642','FE0F','1F482','200D','2640','FE0F','1F477','1F477','200D','2642','FE0F','1F477','200D','2640','FE0F','1F934','1F478','1F473','1F473','200D','2642','FE0F','1F473','200D','2640','FE0F','1F472','1F9D5','1F935','1F470','1F930','1F931','1F47C','1F385','1F936','1F9B8','1F9B8','200D','2642','FE0F','1F9B8','200D','2640','FE0F','1F9B9','1F9B9','200D','2642','FE0F','1F9B9','200D','2640','FE0F','1F9D9','1F9D9','200D','2642','FE0F','1F9D9','200D','2640','FE0F','1F9DA','1F9DA','200D','2642','FE0F','1F9DA','200D','2640','FE0F','1F9DB','1F9DB','200D','2642','FE0F','1F9DB','200D','2640','FE0F','1F9DC','1F9DC','200D','2642','FE0F','1F9DC','200D','2640','FE0F','1F9DD','1F9DD','200D','2642','FE0F','1F9DD','200D','2640','FE0F','1F9DE','1F9DE','200D','2642','FE0F','1F9DE','200D','2640','FE0F','1F9DF','1F9DF','200D','2642','FE0F','1F9DF','200D','2640','FE0F','1F486','1F486','200D','2642','FE0F','1F486','200D','2640','FE0F','1F487','1F487','200D','2642','FE0F','1F487','200D','2640','FE0F','1F6B6','1F6B6','200D','2642','FE0F','1F6B6','200D','2640','FE0F','1F9CD','1F9CD','200D','2642','FE0F','1F9CD','200D','2640','FE0F','1F9CE','1F9CE','200D','2642','FE0F','1F9CE','200D','2640','FE0F','1F468','200D','1F9AF','1F469','200D','1F9AF','1F468','200D','1F9BC','1F469','200D','1F9BC','1F468','200D','1F9BD','1F469','200D','1F9BD','1F3C3','1F3C3','200D','2642','FE0F','1F3C3','200D','2640','FE0F','1F483','1F57A','1F574','1F46F','1F46F','200D','2642','FE0F','1F46F','200D'
