在php passthru中使用变量

Question

I would like to put my variables inside my passthru,

$cut1 =DNAseq1 
$cut2 = DNAseq2

I have already checked this topic but didn't find how to proceed

echo passthru('sudo docker run my_docker bash -c "-check "' .$cut1.'"  "'.$cut2);

but nothing is displayed on the screen but when I wrote directly the DNAseq1:

echo passthru('sudo docker run my_docker bash -c "-check ATCG "'.$cut );

It works....but only when I wrote one variable not for 2
So what is the problem ??

Answer 1

Try this:

echo passthru("sudo docker run my_docker bash -c '/home/prg/soap -check $cut1 $cut2'");

I've used double quotes around the argument to passthru() so I can substitute variables more clearly.
