Custom log helper for CodeIgniter framework
For the last few months we were working with the PHP CodeIgniter framework. Every time I was debugging and wanted to write down some variable I had to write this log_messge('error', $tog_this_var ). 18 characters! Horrible. If the variable was boolean, object or array I'd have to write more or add some if statements. So I decided to write a small helper. Maybe you will find it useful.
<?
if ( !function_exists('l') && !function_exists('l2') && !function_exists('get_parameter_value') )
{
function get_parameter_value($param = null)
{
if (is_null($param)){
return 'NULL';
}else if (!isset($param)){
return "parameter is not SET";
}else if(is_array($param)){
if (empty($param)){
return "empty array()";
}else{
return print_r($param, true);
}
}else if(is_string($param) || is_float($param) || is_int($param)){
return $param;
}else if (is_bool($param)){
return ($param) ? 'TRUE' : 'FALSE';
}else if (is_object($param)){
return var_export($param, true);
}else{
return "UNKNOWN TYPE";
}
}
function l($param1 = null, $msg_prefix = null)
{
return log_message('error', (is_string($msg_prefix) ? " "
. $msg_prefix : "") . get_parameter_value($param1) );
}
function l2($param1 = null, $param2 = null)
{
return log_message('error', get_parameter_value($param1) . " " . get_parameter_value($param2));
}
}else{
log_message('error', __FILE__ . ' - function l, l2, get_parameter_value not created ');
}
?>
<?
// example
l($unknow_variable);
?>
