在PHP中使用echo的正确语法[关闭]

Question

I run this code, and got this error:

 Parse error: syntax error, unexpected T_LNUMBER in C:\xampp\htdocs\Generate.php on line 5

What is the problem?

<?php
$satr=$_POST["satr"];
$soton=$_POST["soton"];
$bg=$_POST["bg"];
echo ("<table border="1" style="background-color:$bg">");
for($i=1;&i<=$satr;$i++)
{
    echo("<tr>");
    for($j=1;j<=$soton;$j++)
    {
        echo("<td>$soton</td>");
}
echo("</tr>");
}
echo("</table>");    

?>

Answer 1

You are not escaping the quotes in the string. You need to do something like this:

echo ("<table border=\"1\" style=\"background-color:$bg\">");
