preg_match help

[tobeyt23]

With the below I would like to get them to return true if grades 9-12, 6-8 or 1-5 respectfully. This doesn't seem to work!

 

<?php
preg_match('/[{9}{10}{11}{12}]/',$book['grade_level'])
preg_match('/[{6}{7}{8}]/',$book['grade_level'])
preg_match('/[{1}{2}{3}{4}{5}]/',$book['grade_level'])
?>

Does $grade_level contain just a number eg, 10 If so you can do

 

if($grade_level >= 9 && $grade_level <= 12)
{
    // grade level is 9 to 12
}
elseif($grade_level >= 6 && $grade_level <= 
{
    // grade level is 6 to 8
}
elseif($grade_level >= 1 && $grade_level <= 5)
{
    // grade level is 1 to 5
}
else
{
    // grade level is unknown.
}

@wildteen: No, you can't do if (something >= 1 && <= 2).  You need to list the variable twice.

<?php
$grade_level = 10;
if ($grade_level >= 9 && $grade_level <= 12) {
....
