single array to multidimensional

[frizzle]

Hi there,

I have a string, comma separated, with links and their respective URLs
in it. Example:
Google,http://www.google.com, Yahoo!,http://www.yahoo.com,WikiPedia,http://www.wikipedia.org

etc, etc.

i make an array of this with explode( ',', $string );

now what i wonder is how can i turn this array into something like
this:

$array[0]['name'] = Google
$array[0]['url'] = http://www.google.com
$array[1]['name'] = Yahoo!
$array[1]['url'] = http://www.yahoo.com
$array[2]['name'] = WikiPedia
$array[2]['url'] = http://www.wikipedia.org

I hope/think this is all clear ...

Something like the following should do it:

$a = explode(",", $string)
for($i=0,$j=0; $i<count($a), $i+=2,$j++) {
$array[$j]["name"] = $a[$i];
$array[$j]["url"] = $a[$i+1];
}

<?php
$str =
"Google,htt p://www.google.com, Yahoo!,http://www.yahoo.com,W ikiPedia,http://www.wikipedia.o rg";
$parts = explode(',', $str);
$array = array();
for ($i=0; $i<count($parts )/2; $i++)
{
$array[$i]['name'] = $parts[$i*2];
$array[$i]['url'] = $parts[$i*2+1];
}

print "<pre>";
var_export($arr ay);
print "</pre>"
?>

There are undoubtably faster, more concise and cleverer ways of doing this.

Thank you both! They look quite complex to me, but i understand what
they do,
by using the arrays index keys.

Thanks again!

Ooh, seems to be "comma separated string" week.

Rik and Andy J. proved regular expressions was faster and says it is the
clever thing to do. But I am not sure about concise.

$string
= "Google,htt p://www.google.com, Yahoo!,http://www.yahoo.com,W ikiPedia,http://www.wikipedia.o rg";

function mickey($minnie, $goofy=null) {
static $pluto = array();
if ($goofy) return $pluto;
$pluto[] = array('name'=>$ minnie[1],'url'=>$minnie[2]);
return $goofy;
}

preg_replace_ca llback('/([^,]*),([^,]*),?/','mickey',$str ing);

$array = mickey('loves', 'minnie');

print_r($array) ;

Which would involve, of course, regular expression :-)

preg_match_all( '/(?P<name>[^,]+),(?P<url>[^,]+)/', $list, $m,
PREG_SET_ORDER) ;

Enjoy!

Ah ha, was trying to work out how to get it with PCRE, knew it was possible

I'm sorry, but i don't completely understand the logics in the
Disny-function, and i don't completely understand the logics in the
pattern of the preg_match_all part.

Could someone please explain a little bit more ?

Especially the "?P" - part in the pattern i cannot figure out ...

The use of (?P<> ... ) indicates named capturing. It only affects how
the captured texts are referenced. Neither the P, the angle brackets,
or the text inside them are a part of the pattern. Thus

/(?P<name>[^,]+),(?P<url>[^,]+)/

is the exact same pattern as

/([^,]+),([^,]+)/

Compare the results from using the two and you'll see the difference.
Here a code snippet:

<?php

header('Content-Type: text/plain');
$list = "Google,htt p://www.google.com" ;
preg_match_all( '/([^,]+),([^,]+)/', $list, $m1, PREG_SET_ORDER) ;
preg_match_all( '/(?P<name>[^,]+),(?P<url>[^,]+)/', $list, $m2,
PREG_SET_ORDER) ;
var_dump($m1);
var_dump($m2);

?>

Look in the manual for how preg_match_all( ) works.

Ok, thanks, this named capturing is new to me, but looks kind of ideal!
Thanks a lot guys!

I have one little question left, not really essential, but to clean
things up:
can the preg-match-all be adjusted that output would be

[0] => Array
(
[name] => Google
[url] => http://www.google.com
)

instead of (current):

[0] => Array
(
[0] => Google,http://www.google.com
[name] => Google
[1] => Google
[url] => http://www.google.com
[2] => http://www.google.com
)

per name/url -set ?
