Re: how to get var name and value from function?

hi, this one I can't figure out: I have to assign value of an array to variable named after key of the array several times in my project to , e.g. after I submit a form with personal info I have $_POST['name'] = 'john doe'; $_POST['address'] = '123 main st.'; $_POST['city'] = 'urbandale'; $_POST['zip'] = '12345'; $_POST['phone'] = '123-456-7980'; etc. Then I assign value to the var name: foreach ($_POST as $key => $value) {

    ${$key} = $value;

} and then validate submitted. Though, to avoid writing all over again the same lines (even it's only 3 lines) I was thinking to create a function something like: function value2var($array, $print=0) {

    foreach ($_POST as $key => $value)
    {
        ${$key} = $value;
        echo ($print ==1) ? $key.': '.$value.'<br>';     // to test

results and seeing array variables and values

    }

} value2var($_POST, 1); but, I don't know how to get info from function back to script?!?!? :-( any help appreciated. -afan well, I would do something like this.

function value2var($in, $wanted=array(), $print=false) { if ( ! is_array($wanted) ) { $tmp = array($wanted); } else { if ( count($wanted) > 0 ) { $tmp = $wanted; } else { $tmp = array_keys($in); } } $myArr = array(); foreach ($tmp as $key) { if ( isset($in[$key]) && !empty($in[$key]) ) { $value = validate_data($in[$key], $key); } $value = ''; } $myArr[$key] = $value; // to test results and seeing array variables and values if ( $print ) echo $key.': "'.$value.'"<br>'; } } return $myArr; } // Say $_POST looked like this $_POST['first_name'] = 'John'; $_POST['last_name'] = 'Doe'; $_POST['address1'] = '123 Someplace Dr.'; $_POST['something_else'] = 'Some Value'; $wanted = array('first_name', 'last_name', 'address1'); extract(value2var($_POST, $wanted, TRUE), EXTR_SKIP, 'CLEAN'); // The EXTR_SKIP option will force extract not to create the variable if it already exists. // Check out http://us2.php.net/extract for other options that could replace EXTR_SKIP // After running the above line, you should end of with the variables that follow echo $CLEAN_first_name; // This should echo John echo $CLEAN_last_name; // This should echo Doe echo $CLEAN_address1; // This should echo 123 Someplace Dr. // and the something_else variable will not have been created as $CLEAN_something_else, because it did not exist in the $wanted array -- Enjoy, Jim Lucas Different eyes see different things.
