Question

I have google thoroughly, and cannot find the solution on how to discard the second dimension array in PHP leaving just the first dimension array.

From:

array(
  ['type'] => 'func'
  ['function'] => 'Model_Statement_Transaction::sum'
  ['parameters'] =>  
    stdClass(
      statement_id = 8586
      transaction_type = 'raw_flour-import'
      column = 'quantity'
    )
)

To:

array(
  ['type'] => 'func'
  ['function'] => 'Model_Statement_Transaction::sum'
  ['parameters'] => ''
)

Answer 1

You use array_map

$parameters = new stdClass();
$parameters->statement_id  = 8586 ;
$parameters->transaction_type   = 'raw_flour-import' ;
$parameters->column  = 'quantity' ;

$array = array('type' => 'func',
        'function' => 'Model_Statement_Transaction::sum',
        'parameters' => $parameters);

$array = array_map(function ($v){if (is_array($v) || is_object($v)) {return "";}return $v;}, $array);
var_dump($array);

Output

array
  'type' => string 'func' (length=4)
  'function' => string 'Model_Statement_Transaction::sum' (length=32)
  'parameters' => string '' (length=0)
