PHP自动检查复选框不起作用

I have an automatic check system that is not working properly

while($linha = mysql_fetch_array($tabela))
{
    $nome = $linha['TABLE_NAME'];

    ?>

        <input type="checkbox" name="<?php echo $nome ?>" id="<?php echo $nome ?>" value="<?php echo $nome ?>" <?php if(isset($_POST[$nome]))  echo "checked='checked'";?>/> <?php echo $nome ?><br />

    <?php
}

The problem is the $nome variable, it have spaces, like 'A B' or '106 South', doing the system not works correctly... I don't know how to solve it, any help will be welcome!

    The problem lies with the fact that you're using spaces in the name attribute of the input tag. See this reference:

    ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

    This has also been addressed in other SO questions

    Spaces are not allowed and will not work properly when you submit them using either POST or GET methods. You should therefore rename any values with spaces or use a str_replace function to substitute the spaces with underscores or something similar. Also note the part that said "must begin with a letter"... this also means that a value of 106 Sul is invalid even if you changed it to 106Sul.
