Question

Is there a more elegant way to concat multiple variables as opposed to the ‘procedural’ method in PHP?

For example lets consider this situation:

$sql_columns = $sql_values = '';
foreach ($this->_data as $column => $value)
{
    // How i d like to do it
    // list ($sql_columns, $sql_values) .= array(", $column", ', ?'); #Error

    // procedural method
    $sql_columns .= ", $column";
    $sql_values  .= ', ?';
}

Answer 1

You could do:

$sql_columns = implode(', ', array_keys($this->_data));
$sql_values = rtrim(str_repeat('?, ', count($this->_data)), ', ');
