This article to introduce the PHP anti-Chinese character to Unicode encoding implementation program method, there is a need to understand the friend can enter the reference.
Program
| The code is as follows |

Examples of Use:
| The code is as follows |
Copy Code |
GBK string Test
$str = ' haha ';
echo $str. '
';
$unistr = Unicode_encode ($STR);
echo $unistr. '
'; <b> haha </b>
$str 2 = Unicode_decode ($UNISTR);
echo $str 2. '
'; haha
UTF-8 string Test
$utf 8_str = iconv (' GBK ', ' UTF-8 ', $str);
echo $utf 8_str. '
'; ???? Note: UTF shows the garbled characters under GBK! Switchable Browser-coded test
$utf 8_unistr = Unicode_encode ($utf 8_str, ' UTF-8 ');
echo $utf 8_unistr. '
'; <b> haha </b>
$utf 8_str2 = Unicode_decode ($utf 8_unistr, ' UTF-8 ');
echo $utf 8_str2. '
'; // ????
Other suffixes, prefix tests
$prefix _unistr = Unicode_encode ($str, ' GBK ', ' \u ', ');
echo $prefix _unistr. '
'; U60u98u62u21704u21704u60u47u98u62
$profix _unistr2 = Unicode_decode ($prefix _unistr, ' GBK ', ' \u ', ');
echo $profix _unistr2. '
'; haha |
