PHP将变量与加号进行比较

Question

If I have a value of 1+ in a VARCHAR column in a MySQL table, how can I compare this variable in php?

 if ($days=="1+") 

does not appear to work, so how to compare it including the plus sign?

Answer 1

If in your database if you days column as varchar, than you will get the exact value (even with +), so:

if($days == "1+") is true

a more complete code for you to try

$res = mysql_query("SELECT days FROM table");
while( $row = mysql_fetch_assoc($res) ) {
    if($row["days"] == "1+") echo 'found' . '<br>';
}
