Emoji Name Search Timezone Tutorial<\/p><\/div>\n

Yesterday’s Emoji Name Search Map Tutorial<\/a> was a step in the direction of “where” functionality, but because PHP teams up with the supervisory HTML “Emoji World Flags” web application, to make all this happen, there is the opportunity to add interest by adding a “when” aspect to how it works.<\/p>\n

As we’ve said many times now, should you have access to PHP, you also have access to its DateTimeZone<\/a> class where Timezones can be linked to ISO 2 letter Country Codes, useful as an integration point as of recent times when we introduced ISO 2 letter Country Codes to today’s (supervisory) live run<\/a>‘s world_flags.html<\/a> HTML and Javascript code.<\/p>\n

But it is not HTML code that changes today. It is its PHP partner emoticon_keyboard_shortcuts.php<\/a> changed in this way<\/a>, that arranges that its call of Google Charts<\/a> Map Chart<\/a> passes across a new URL …<\/p>\n


\n&ccode=[ISO 2 letter Country Code]
\n<\/code><\/p>\n

… argument that uses a new PHP function as below (arrays shortened for practicality purposes) …<\/p>\n


\n<?php
\n function inctycodecheck($incd, $sofar) {
\n $nearname=[\"Africa\/Abidjan\",\"Africa\/Accra\", ... ]; \/\/ array of Timezone names
\n $retv=\"\";
\n $retd=\"\";
\n $otz = new DateTimeZone(\"UTC\");
\n $jj=0;
\n $origin_dt = new DateTime(\"now\", $otz);
\n for ($best1=0; $best1<sizeof($nearname); $best1++) {
\n try {
\n $tz = new DateTimeZone($nearname[$best1]);
\n $cloc = $tz->getLocation();
\n $ctrycode = $cloc['country_code'];
\n if (strtoupper($incd) == strtoupper($ctrycode)) {
\n $remote_dt = new DateTime(\"now\", $tz);
\n $offset = ($tz->getOffset($remote_dt) - $otz->getOffset($origin_dt)) \/ 3600;
\n $newp=$retd . $nearname[$best1] . \"\/\" . $remote_dt->format('Y-m-d_H:i:s') . \" (GMT\" . $offset . \")\";
\n $huhs=explode(\" (GMT\" . $offset . \")\", $retv);
\n if (sizeof($huhs) == 2) {
\n if (explode(\"\/\", $newp)[0] != explode(\"\/\", explode(\",\", $huhs[0])[-1 + sizeof(explode(\",\", $huhs[0]))])[0]) {
\n $huhs=explode(\"youwillneverfindthis\", $retv);
\n }

Emoji Name Search Map Tutorial<\/p><\/div>\n

Yesterday’s posted data Emoji Name Search Posting Tutorial<\/a> functionality opened the door to “where” web application (software) integration, because the wonderful Wikipedia<\/a> has compiled Latitude,Longitude co-ordinate pairs for those countries, and that is our foot in the door to place an HTML a<\/i> link under the Emoji flags, that points to our favourite “where” interfacing tool, the Google Charts<\/a> Map Chart<\/a>.<\/p>\n

Because the Map Chart and Emoji Flag web application share the same domain we can keep this functionality on this same Emoji Flag webpage in an …<\/p>\n
