PHP decrypts Unicode and Escape encrypted strings

Chinese is not supported in json. If you use it to transmit Chinese data, data will be lost or garbled. You must send it before sending it. The string is encoded. Since the transmission requires js for data parsing, considering that there is an unescape function in js, if there is an escape function in php, the data is encoded and unescape is used to decode it on the client. This will Much more convenient.

This article will share with you a PHP decryption Unicode and Escape encrypted string function

function uni_decode($s) {

preg_match_all('/([0-9]{2,5});/', $s, $html_uni);

preg_match_all('/[\%]u([0-9a-f]{4})/ie', $s, $js_uni);

$source = array_merge($html_uni[0], $js_uni[0]);

$js = array();

for($i=0;$i

$js[] = hexdec($js_uni[1][$i]);

}

$utf8 = array_merge($html_uni[1], $js);

$code = $s;

for($j=0;$j

$code = str_replace($source[$j], unicode2utf8($utf8[$j]), $code);

}

return $code;//$s;//preg_replace('/\u([0-9a-f]{4})/ie', "chr(hexdec(''))", $s);

}

function unicode2utf8($c) {

$str="";

if ($c

$str.=chr($c);

} else if ($c

$str.=chr(0xc0 | $c>>6);

$str.=chr(0x80 | $c & 0x3f);

} else if ($c

$str.=chr(0xe0 | $c>>12);

$str.=chr(0x80 | $c>>6 & 0x3f);

$str.=chr(0x80 | $c & 0x3f);

} else if ($c

$str.=chr(0xf0 | $c>>18);

$str.=chr(0x80 | $c>>12 & 0x3f);

$str.=chr(0x80 | $c>>6 & 0x3f);

$str.=chr(0x80 | $c & 0x3f);

}

return $str;

}

$str='%u5927%u5BB6%u597D%uFF0C我是孤魂！
u8FD9u662Fu6D4Bu8BD5u6587u672CuFF01';

echo uni_decode($str); // 大家好，我是孤魂！这是测试文本！

Search on the Internet, there are many escape functions implemented in php, they are similar

function phpescape($str){

preg_match_all("/[x80-xff].|[x01-x7f] /",$str,$newstr);

$ar = $newstr[0];

foreach($ar as $k=>$v){

if(ord($ar[$k])>=127){

$tmpString=bin2hex(iconv("GBK","ucs-2",$v));

if (!eregi("WIN",PHP_OS)){

$tmpString = substr($tmpString,2,2).substr($tmpString,0,2);

}

$reString.="%u".$tmpString;

} else {

$reString.= rawurlencode($v);

}

return $reString;

}

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
