How to Dump the Generated Zend_Db SQL Query

PHP, zend framework, , , , , , , , , ,

The Typical PHP Approach

Typically a PHP programmer will write his SQL query as a string and will execute it via mysql_query.

$sql = "SELECT * FROM my_table";
$resource = mysql_query($sql);

So eventually when you want to dump this “complex” query, or whatever query there is, you can simply “echo” it and see what’s its syntax.

// this query is WRONG because of the where clause
$sql = "SELECT * FROM my_table WHERE id = ";
 
// dump and debug the wrong query
die($sql);
 
// this line won't be executed
$resource = mysql_query($sql);

So far so good, but things appear to be a bit different when you start to work with Zend Framework. Higher levels of abstraction come with slightly more difficult ways to dump (debug) your SQL queries.

OK you’ve two options. Using Zend_Db_Select or … not.

PHP Associative Arrays Coding Style

micro tutorial, PHP, , , , , , , , , , , , , ,

No PHP programmer writes code without arrays. Sound strange, but as many programmers there are, as many ways to format the array notation there are.

My advice is to rely on a defined standard. I personally use the Zend Framework’s coding style.

So how to format the code? The first way is on the same line:

$myArray = array('key1' => 'value1',
		 'key2' => 'value2');

And the other, perhaps more clear way is to place the associative pairs on a new line:

$myArray = array(
	'key1' => 'value1',
	'key2' => 'value2',
);

Note that in the second example there’s a comma after the second pair. This is correct PHP syntax and is strongly encouraged!

It’s up to you which way to take. However it mainly depends on the case, but please use standards.
