Determine if the first character is a 0

[treeleaf20]

All,

I have a zip code and for example the zip code is 01101. How can I determine if the first character in this is a zero?

 

Thanks in advance.

Try using substr.

There are a multitude of ways to do this.

 

Another way:

$zip = "01101";
echo $zip[0];

if(strpos($zip, '0') === 0) {
  //yes
}
