TRUE or FALSE returns from bools

[tet3828]

Quick question.

 

I was reading through some functions in the php manual  I am intrested in using the mkdir function for a project I am working on. The manual says it returns true if it succeeded and a false if it failed.

 

This may be basic and I've prob even done it with other functions but...

 

how can I check the value it returned?

 

so far I have:

 

mkdir ("TRAINING SESSION");

 

so what do I do now?

 

if mkdir == false {return error} ???

<?php

$dir_name = 'TRAINING_SESSION';

  mkdir($dir_name);

    if(is_dir($dir_name)) {
      echo'Cool. It worked';
    }
      else
      {
         echo'Negatory, my friend.';
      }

?>

Also...I'm guessing for it to work...the directory you're throwing that folder into, must be writable. Haven't used the function in a long time.

You could also assign the function to a variable then test the variable.

 

$directory = mkdir($dir_name);

if ($directory===true) {
//do this
} else {
//do this
}

You could also assign the function to a variable then test the variable.

 

You can also simply test it as you use it.

 

<?php

  if (mkdir ("TRAINING_SESSION")) {
    echo 'mkdir successfull';
  } else {
    echo 'mkdir failed';
  }

?>

 

ps: Directories (just as files) should not have spaces in there names.

yep, as thorpe suggests mkdir returns true or false.

depending if it succeeded or not.

 

so there is no need to use other functions (is_dir) to check if it succeeeded.

 

since it returns a numeric, ya can use it as an expression (if,while,switch).

 

you will find a lot of functions that return simple information like this, so is of great use.
