我有一本像
UUU F
UUC F
CUU L
CUC L
UUA L
CUA L
UUG L
CUG L
AUU I
AUC I
AUA I
GUU V
GUC V
GUG V
GUA V
所以给定一个字符串,我想每 3 个字符替换它各自的字符
我正在考虑使用关联数组:
$d = array();
$d['UUU']='F';
$d['UUC']='F';
$d['UUA']='L';
$d['CUU']='L';
$d['GUC']='V';
$d['GUG']='V';
$d['GUA']='V';
$d['UUG']='L';
$d['CUG']='L';
$s = "UUAGUAUUG";
$temp="";
for($i=0; $i<strlen($s)+1; $i++){
$temp .= $s[$i];
if($i%3==0){
echo $temp;
echo array_search($temp, $d);
$temp = "";
}
}
It should output LVL but have no success
