代码很简单,功能却很实用,推荐给大家。

奉上代码先:

复制代码代码如下:


public function utf8_unicode($str) {
$unicode = array();
$values = array();
$lookingFor = 1;
for ($i = 0; $i $thisValue = ord( $str[ $i ] );
if ( $thisValue // exclude 0-9
if ($thisValue >= ord('0') && $thisValue // number
$unicode[] = chr($thisValue);
}
else {
$unicode[] = '%'.dechex($thisValue);
}
} else {
if ( $thisValue $unicode[] = $str[ $i ];
} else {
if ( count( $values ) == 0 ) {
$lookingFor = ( $thisValue }
$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();
$lookingFor = 1;
} // if
} // if
}
} // for
return implode("",$unicode);
}
