TeddyKiller Posted April 12, 2010 Share Posted April 12, 2010 I have a Users DOB put into Age. If this Age is bigger than 18 (for example) then display certain information. $age would be the variable to hold the string of their age. How can I do this? I'm imagining simply doing if($age > 18) wouldn't do the job.. as $age is a string. . . Quote Link to comment Share on other sites More sharing options...
the182guy Posted April 12, 2010 Share Posted April 12, 2010 Why not just cast $age as an integer like if((int)$age > 18) Quote Link to comment Share on other sites More sharing options...
TeddyKiller Posted April 12, 2010 Author Share Posted April 12, 2010 I haven't used (int)'s before. Thanks Quote Link to comment Share on other sites More sharing options...
ignace Posted April 12, 2010 Share Posted April 12, 2010 use strcmp: Returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2, and 0 if they are equal. Quote Link to comment Share on other sites More sharing options...
Ken2k7 Posted April 12, 2010 Share Posted April 12, 2010 I haven't used (int)'s before. Thanks If you're not comfortable with that method of casting, use intval. I prefer to compare numbers as numbers rather than as strings with strcmp. Quote Link to comment Share on other sites More sharing options...
