PHP Treasures

I’ve been coding PHP for six years now and have gotten quite fluent and adept over the years. But every once in awhile, I’ll rediscover a long-lost gold mine of a function that is so perfect and so simple yet has been forgotten.

Enter

1
<a href="http://www.php.net/array_push/">array_push()</a>

. This function basically takes a value and pops it on the end of an existing array. For instance, a simplistic usage example is:

1
2
3
4
5
$animals = array('cat', 'dog', 'bird');

array_push($animals, 'lizard');

print_r($animals);

// displays 

// Array [0] => cat [1] => dog [2] => bird [3] => lizard

Pretty basic, but imagine how useful it is when I want to do form validation on a bunch of submitted vales?

1
2
3
4
5
6
7
8
9
if(!validateField('a_username',$a_username))

    array_push($validation_errors, validateField('a_username',$a_username));

if(!validateField('a_password', $a_password))

    array_push($validation_errors, validateField('a_password', $a_password));



print_r($validation_errors);

// displays:

// Array [0] => Username already taken [1] => Password 

//    length is too short. Must be between 6-16 characters

How did I forget about this function? It’s a Godsend…

    Or you could use the following:

    $animals = array(‘cat’, ‘dog’, ‘bird’);
    $animals[] = ‘lizard’;
    print_r($animals);
    // displays
    // Array [0] => cat [1] => dog [2] => bird [3] => lizard

    which is much easier.

    $animals[] = ‘lizard’;
    print_r($animals);
    // displays
    // Array [0] =&gt; cat [1] =&gt; dog [2] =&gt; bird [3] =&gt; lizard

    which is much easier.
