我想增加我的变量，但它只显示字符串。 （输出：$ bgcolor1）

I have a couple of variables, and after I increase the numbers, it only shows $bgcolor1. But I want that it write out this: bgcolor='#0066CC'. I just cannot figure out the solution. Hope someone can help me. Thanks!

$bgcolor1 = "bgcolor='#0066CC'";
$bgcolor2 = "bgcolor='#FF0000'";
$bgcolor3 = "bgcolor='#00FF00'";


for ($c = 1; $c <=5; $c++){

    print "<table border='1' ".'$bgcolor'.$c.">";

}               

$bgcolor1 = "bgcolor='#0066CC'";
$bgcolor2 = "bgcolor='#FF0000'";
$bgcolor3 = "bgcolor='#00FF00'";

for ($c = 1; $c <=5; $c++){
    print "<table border='1' ".${"bgcolor".$c}.">";
}

Try this:

$bgcolor1 = "bgcolor='#0066CC'";
$bgcolor2 = "bgcolor='#FF0000'";
$bgcolor3 = "bgcolor='#00FF00'";


for ($c = 1; $c <=5; $c++){
    $bgcolor = "{$bgcolor}{$c}";
     print "<table border='1' ". $bgcolor . ">";
} 

Try putting the colors in an array, then looping over the array and printing them out.

$bgcolors = array("bgcolor='#0066CC'", "bgcolor='#FF0000'", "bgcolor='#00FF00'");

for ($c = 0; $c < 3; $c++){

    print "<table border='1' " . $bgcolors[$c] . ">";

}
