Question

I have this loop:

for ($m=0; $m<7; $m++){
if ($myextra[$m] == $drawextra[$m]) {
$myextra[$m] = '<span class="matchx">'.$myextra[$m].'</span>';
}
}
echo $myextra;

My echo output is as follows:

 3445<<8
<11<<6<
<45<<<<

The class in the is from my stylesheet and should color the matched character in the string but the matched character is simply replaced by ‘<‘. They are in the correct position but how can I assign that class properly?

Answer 1

You cannot use [] notation to change more than one char in string.
You have to use new variable:

$result = '';
for ($m=0; $m<7; $m++){
    if ($myextra[$m] == $drawextra[$m]) {
        $result .= '<span class="matchx">'. $myextra[$m] .'</span>';
    } else {
        $result .= $myextra[$m];
    }
}
echo $result;
