One of the PEAR packages I have a love/hate relationship with is Structures_Datagrid….

This code allows for the usual array([objectname],[methodname]) calling structure of php.
A second array can be supplied for arguments, to be supplied either as real arguments or an array of arguments

$myObj = new myobj;

$this->formatter = array(array($myObj,’eat’),array(‘banana’,'tomato’));
will call: $myObj->eat(‘banana’,'apple’)

$this->formatter = array(array($myObj,’eat’),array(‘fruit’=>’banana’,'vegetable’=>’tomato’));
will call: $myObj->eat(array(‘fruit’=>’banana’,'vegetable’=>’tomato’,'record’=>…))

function formatter($record)
{

if (empty($this->formatter[0])) {
return false;
}

$parameters = false;
$calluserfuncarray = false;
if (empty($this->formatter[1])) {
if (!empty($this->fieldName)){
$parameters = $record[$this->fieldName];
}
} else {
$parameters = array(‘record’ => $record);
if (is_array($this->formatter[1])) {
foreach ($this->formatter[1] as $key=>$value){
$calluserfuncarray |= is_numeric($key);
if ($calluserfuncarray) break;
}
if (!$calluserfuncarray)
$parameters = array_merge(array(‘record’ => $record), $this->formatter[1]);
}
}

// Call the formatter
if (is_callable($this->formatter[0])) {
if ($calluserfuncarray)
return call_user_func_array($this->formatter[0], $this->formatter[1]);
return call_user_func($this->formatter[0], $parameters);
} else {
//$result = new PEAR_Error(‘Unable to process formatter’);
$result = false;
PEAR::raiseError(‘Unable to process formatter’, ’1′,
PEAR_ERROR_TRIGGER);
}
}
