我在PHP中製作動態Unicode圖標。我想要Unicode圖標的UTF-8代碼。在PHP中使用動態Unicode創建UTF-8代碼
到目前爲止,我已經做了:
$value = "1F600";
$emoIcon = "\u{$value}";
$emoIcon = preg_replace("/\\\\u([0-9A-F]{2,5})/i", "&#x$1;", $emoIcon);
echo $emoIcon; //output
$hex=bin2hex($emoIcon);
echo $hex; // output 26237831463630303b
$hexVal=chunk_split($hex,2,"\\x");
var_dump($hexVal); // output 26\x23\x78\x31\x46\x36\x30\x30\x3b\x
$result= "\\x" . substr($hexVal,0,-2);
var_dump($result); // output \x26\x23\x78\x31\x46\x36\x30\x30\x3b
但是,當我直接就把價值,它打印正確的數據:
$emoIcon = "\u{1F600}";
$emoIcon = preg_replace("/\\\\u([0-9A-F]{2,5})/i", "&#x$1;", $emoIcon);
echo $emoIcon; //output
$hex=bin2hex($emoIcon);
echo $hex; // output f09f9880
$hexVal=chunk_split($hex,2,"\\x");
var_dump($hexVal); // output f0\x9f\x98\x80\x
$result= "\\x" . substr($hexVal,0,-2);
var_dump($result); // output \xf0\x9f\x98\x80
請澄清你的問題。你想實現什麼? –
