Errors

From KnowledgeTree Community

All exceptions and errors in code should be handled with the PEAR::Error class. Using this is straightforward, and can be demonstrated with a quick piece of code.

 ...

 function testme($my_value) {
      if (!is_int($my_value)) {
          return PEAR::raiseError("Please give me a number to work with");
      } else {
          return $my_value * 10;
      } 
 }

 $new_val = testme("boo");
 if (PEAR::isError($new_val)) {
     printf ("Couldn't do it, captain:  %s", $new_val->getMessage());
 } else {
    printf("I had the power, captain!  Answer is %d", $new_val);
 }
