如何在php中使用分隔符获取数组中的值

Question

I have already stored data in array and I want to get value in each id that separated with ","

Example:

sql table:

ruleID | symptomID | penyakit
R1     |  s1,s2    | DD
R2     |  s1,s2,s3 | DD

Php code:-

while ($row = mysql_fetch_array($query)) {

    $allS = $row['symptomID'];
    $penyakit = $row['penyakit'];

    if ($penyakit == 'DD') {
        $arrRuleDenggi[] = $allS;
    }
}

I've already tried print_r(explode(",",$arrRuleDenggi) but it doesn't work.I just wanna take value without commas..

Assuming that your array is

 $arraySymp = array(0=>"s1,s2", 1=>"s1,s2,s3");

you can

foreach($arraySymp as $inner)
    foreach(explode(",", $inner) as $inner_inner)
        echo $inner_inner."
";
