php實(shí)現(xiàn)utf-8轉(zhuǎn)unicode函數(shù)分享
php實(shí)現(xiàn)utf-8轉(zhuǎn)unicode函數(shù)如何操作呢?需要的朋友可以參考下,代碼很簡單,功能卻很實(shí)用,推薦給大家。希望對大家有所幫助!
奉上代碼先:
復(fù)制代碼 代碼如下:
public function utf8_unicode($str) {
$unicode = array();
$values = array();
$lookingFor = 1;
for ($i = 0; $i < strlen( $str ); $i++ ) {
$thisValue = ord( $str[ $i ] );
if ( $thisValue < ord('A') ) {
/pic/p>
if ($thisValue >= ord('0') && $thisValue <= ord('9')) {
/pic/p>
$unicode[] = chr($thisValue);
}
else {
$unicode[] = '%'.dechex($thisValue);
}
} else {
if ( $thisValue < 128) {
$unicode[] = $str[ $i ];
} else {
if ( count( $values ) == 0 ) {
$lookingFor = ( $thisValue < 224 ) ? 2 : 3;
}
$values[] = $thisValue;
if ( count( $values ) == $lookingFor ) {
$number = ( $lookingFor == 3 ) ?
( ( $values[0] % 16 ) * 4096 ) + ( ( $values[1] % 64 ) * 64 ) + ( $values[2] % 64 ):
( ( $values[0] % 32 ) * 64 ) + ( $values[1] % 64 );
$number = dechex($number);
$unicode[] = (strlen($number)==3)?"\u0".$number:"\u".$number;
$values = array();
$lookingFor = 1;
} /pic/p>
} /pic/p>
}
} /pic/p>
return implode("",$unicode);
}
