Translit xor crypting c++ to php -

i want translit xor crypting c++ php. use function crypting. want decrypt file php.

wchar_t* encryptdecrypt(const wchar_t* toencrypt, int length,   wchar_t* ebkey) {     const wchar_t* key = ebkey;     wchar_t* output = new wchar_t[length];      (int = 0; < length; i++) {         output[i] = toencrypt[i] ^ key[i % wcslen(key)];     }     return output; } 

i read xls file binary , crypt encryptdecrypt

void encryptandsave(char *src,ansistring key) {     wchar_t *content;     wchar_t  buffer[255];     wchar_t *result;      long size;     long fsize;      file *f=null;      f=fopen(src,"rb+");      fseek(f, 0, seek_end);     size = ftell(f);     fseek(f,0, seek_set);      content = (wchar_t *) malloc(size * sizeof (wchar_t));     fread(content, size, 1, f);     fclose(f);      content=encryptdecrypt(content,size,strtowchar_t(key));      f=fopen(src,"wb+");     fwrite(content, size, 1, f);     fclose(f); } 

i use function convertion key in wchar_t

wchar_t* strtowchar_t(ansistring value) {     int isize = value.widecharbufsize();     wchar_t *tmp = new wchar_t[isize];      value.widechar(tmp,isize);     return tmp; } 

this code in php decrypting

function encryptdecrypt($toencrypt,$key) {     $output=array();     ( $i = 0; $i < strlen($toencrypt); $i++ ) {         $output[$i]= $toencrypt[$i] ^ $key{$i % strlen($key)};     }     return $output; }  

but not rightly decrypting.when crypt , decrypt c++ word, result must "qwerty" "ﻎcdt@gh", in php not work c++. when decrypt "ﻎcdt@gh" in php "яМp1v3e2s1u3y2", must "qwerty". please resolve problem.
