我有这个代码:
function getcolor();
.....other code here
$col=220;
return $color=hsl( $col,'100%','50%');
.. wuth this funcitoni want to get a coloring style for another function here:
function colorSequence ($seq,$position,$color,$TFBSlength){
$nucleotides = str_split($seq);
foreach ($nucleotides as $index => $nucl){
if ($index == $position-1){
echo "<span style=\"color:$color\">";<-- this line wont work ?
}
if ($index == $position-1 + $TFBSlength){
echo "</span>";
.... rest of function.
要着色的输入字符串将是例如
$seq="AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"
$color=getcolor();
基本上我想使用函数colorsequence的参数$color将输入字符串的某个部分着色为某种颜色(它总是会改变)
有人告诉我这部分代码有什么问题吗?
