I like many of the functions that are used and have started to use them already.
I have developed a routine which I use extensively to find the values of any type of variable, integer, string, array or object.
It is easy to use, just type fred('whatever variable type you have');
I include it in my index.php with require('_fred.php') and it makes it available to view the CodeIgniter source code.
Give
fred(...) a try // named because it is very easy to type.
_fred.php
Code:
<?php
define('LOCALHOST', 'localhost' === $_SERVER['SERVER_NAME']);
//==========================================================================
function fred($data='usage: fred("any type of data")', $data_name='missing_$data_name')
{
$data_type = '';
// $data objects do not display as an array so...
if (is_object($data))
{
$data = get_object_vars($data); // returns with $data = array();
}
// maybe find the $data type
if (empty($data))
{
$data_type = "empty()";
}else{
switch($data)
{
case ('' == $data) :
$data_type = "empty()";
break;
case is_array($data) :
$data_count = count($data);
$data_type = "array($data_count)";
break;
case is_bool($data) :
$data_type = 'boolean';
$data = $data ? 'TRUE' : 'FALSE';
break;
case is_numeric($data) :
$data_type = 'numeric';
break;
case is_object($data) :
$data_type = 'object';
$data = get_object_vars($my_class);
break;
case is_resource($data) :
$data_type = 'resource';
$data_count = mysql_num_rows($data);
$tmp = array();
while ($row = mysql_fetch_assoc($data))
{
$tmp[] = $row;
}
$data = $tmp;
break;
case is_string($data) :
$data_type = 'string';
$data_count = strlen($data);
break;
default:
$data_type = 'oddball';
$data_value = $data;
}//end switch
}//endif
// $data must now be an array or a string, numeric, or...
