我有以下代码:
$qSeq = "ATTA";
$suchmuster = array("/A/","/T/","/G/","/C/","/U/");
$ersetzungen = array("T","A","C","G","A");
$qSeq = preg_replace($suchmuster, $ersetzungen, $qSeq);
echo $qSeq;
我的目标是,即ATTA成为TAAT,这种逻辑在Ruby中运行良好,但PHP有点会产生AAAA。知道如何使用PHP吗?
TNX!

如果您的替换可能需要更改您已更改的字母,请使用strtr()
$qSeq = 'CATGUT';
$suchmuster = array("A","T","G","C","U");
$ersetzungen = array("T","A","C","G","A");
$qSeq = strtr($qSeq, array_combine($suchmuster, $ersetzungen));
echo $qSeq;
