Php explode array with specific value - php

Question

I really need some help with this code and I'm not that good at PHP.
Here is the code:
function projectAttr($number){
global $clerk, $project;
$projectid = $project['id'];
$tags = array();
$cleanUrls= (bool) $clerk->getSetting( "clean_urls", 1 );
$getTags = $clerk->query_select ( "projects_to_tags", "DISTINCT tag", "WHERE projectid='$projectid' ORDER BY id ASC" );
while ( $tag= $clerk->query_fetchArray( $getTags ) )
{
$tagset = explode('; ', $tag['tag']);
}
return html_entity_decode($tagset[$number]);
}
The code explodes a string and puts it in a array, that I can get by projectAttr(0). But I want to be more specific in what I want to get from the string.
This is my string:
size='large'; caption='short text about post/project'; bgcolor='black'; color='white';
What I want is, if I write projectAttr(size) it should return the value large and so forth.
Is that even possible?
Thanks, Peter

Answer 1

I'll answer specifically to the explode you want. You should modify your projectAttr function to look this this:
$items = explode('; ', $string);
$attr = array();
foreach($items as $item) {
list($key, $val) = explode('=', $item);
$attr[$key] = str_replace(array("'", ""), '',$val);
}
Which returns
Array (
[size] => large
[caption] => short text about post/project
[bgcolor] => black
[color] => white
)
EXAMPLE DEMO
So modify your function to look like this:
function projectAttr($name) {
global $clerk, $project;
$projectid = $project['id'];
$tags = array();
$cleanUrls = (bool) $clerk->getSetting("clean_urls", 1);
$getTags = $clerk->query_select("projects_to_tags", "DISTINCT tag", "WHERE projectid='$projectid' ORDER BY id ASC");
while ($tag = $clerk->query_fetchArray($getTags)) {
$items = explode('; ', $string);
$attr = array();
foreach ($items as $item) {
list($key, $val) = explode('=', $item);
$attr[$key] = str_replace(array("'", ""), '', $val);
}
}
return html_entity_decode($attr[$name]);
}
And that should allow you to call it like this:
projectAttr('size');

try
function projectAttr($number){
$str= "size='large'; caption='short text about post/project'; bgcolor='black'; color='white';";
$r = explode('; ', $str);
foreach($r as $k=>$v) {
$attr = explode('=', $v);
$projectAttr[$attr[0]] = str_replace("'", "", $attr[1]);
}
return html_entity_decode($projectAttr[$number]);
}
echo projectAttr('size'); // large
