Three very different questions

[patrick99e99]

Hi Everyone.

I have three questions, and am wondering how these things can be achieved in PHP..

#1.

if I have a string:

$cat="meow meow I love to eat Fancy Feat meow meow"

how can I substitute all of the space characters in $cat with "%20"?

#2. if I have a variable:

$var=1

how can I convert it into a 3 digit number --> "001"?

where as it will also work for $var=11 --> "011"

?

#3. if I have many arrays like this:

$item[0]=array ('shoes' => 'nike',
                         'size' => '12',
                         'color' => 'white',
                         'lights' => array ('lamps' => 'floor',
                                                   'sun' => 'sky',
                                                   'stars' => 'space'));

and then several others that are just shoes.

$products[0]=array ('shoes' => 'flip flops',
                                'size' => '10',
                                'color' => 'green')

$products [1]=array.. etc etc.

Lets say I have 15 of these.. How can I add the next $product[15] and on to consist only of the info "shoes, size, and color" from the $item array?

So basically I just want to absorb part of the $item array say $item[0] through $item[20], and begin the absorbing on $product[15] through $product[35]

thank you very much for the knowledge!!!

#1 = str_replace

#2 = str_pad

#3 = You could use a loop.

$total_products = count($products);
for($i = 0; $i <= 20; $i++)
{
$product[$total_products + $i]['shoes'] = $item[$i]['shoes'];

//etc. something like that would work...

}

Also, for the first question, if you're talking about encoding strings so that they can safely be used in a URL, look at using [man]urlencode/man instead.
