substr help

[HCProfessionals]

I have a directory list using variables Folder/ and sub folders with /Folder/, what i need to do is replace the beginning slash if there is one. I'm using a recursive command and if i use substr for example:

 

subtr("$variable", 1); it will always remove the first character. What I need is an if statement or something to check to make sure it is a slash.

Well you simply check the first index of the string, and compare it to a slash. if it is you are safe to remove it

if (!empty($variable) && $variable[0] == "/"){//check if its empty first to avoid possible error
substr($variable, 1);
}
