Hi,

I'm coding a template system for my site with multiple themes and i need to know how to echo things like this:

PHP Code:


		
			
$replace = "['data1','Hi there'],['data2','Hello there']";

I need to explode or something like that with [] as 1 array with 2 data sections.
It's like array but not.

I know how to replace in the site:

PHP Code:


		
			
str_ireplace( "#data1#", "value of data1" );
str_ireplace( "#data2#", "value of data2" );

Is just need to know how to make [] these in to 1 array.

Can anyone help.
Would be very helpful.

Thanks,
Clawed

How'd you end up with a string like that?
If you have a newer version of PHP and the data comes from a completely trusted source, you can use eval:

PHP Code:


		
			
$replace = "['data1','Hi there'],['data2','Hello there']";  

eval("\$a = [$replace];");
print_r($a);

Otherwise you can explode it and then explode each item:

PHP Code:


		
			
$aParts = explode('],[', trim($replace, ']['));
foreach ($aParts AS &$part)
{
    $part = explode("','", trim($part, "'"));        
}
print_r($aParts);

Both of which should result in:

Code:

Array

(

    [0] => Array

        (

            [0] => data1

            [1] => Hi there

        )



    [1] => Array

        (

            [0] => data2

            [1] => Hello there

        )



)

Thanks, i'll try these.

I'm building a template system & it's all MySQL powered, all data comes from MySQL tables & it echos pages with:

Code:

<div>#data1#</div>

<div>#data2#</div>

And so on.

And after row content there's things that i want it to search and replace for example:

PHP Code:


		
			
$content = "<div>#data1#</div>
<div>#data2#</div>";

$string = str_ireplace( "#data1#", "Hi", $content );
$string = str_ireplace( "#data2#", "Hi2", $string );

echo $string;

Edit;
------------------------------------------------------------------------------------

Nope not how i wanted it, i want so i can use foreach() to set a template param, example:

PHP Code:


		
			
$aParts = explode('],[', trim($replace, ']['));
foreach ($aParts AS &$part)
{
    $part = explode("','", trim($part, "'"));
    foreach ($part as $info => $value)
    {
          $template->setParam($info, $value);
    }
}

So when i do:

PHP Code:


		
			
echo $template->params['data1'];

It echos "Hi there"
And same with data2:

PHP Code:


		
			
echo $template->params['data2'];

It echos "Hello there"

Well no, this wouldn't work:

PHP Code:


		
			
    foreach ($part as $info => $value)
    {
          $template->setParam($info, $value);
    }

That indicates that you have $info as something valid other than an offset. What that would do is set param0 and param1 to the value given. What you appear to want to do is this:

PHP Code:


		
			
foreach ($aParts AS $part)
{
    $part = explode("','", trim($part, "'"));
    $template->setParam($part[0], $part[1]);
}

A quick example of what I think you are doing:

PHP Code:


		
			
class T
{
    private $itms;
    public function __construct()
    {
        $this->itms = array();
    }
    public function setParam($p, $v)
    {
        $this->itms[$p] = $v;
    }
    public function getParam($p)
    {
        return @$this->itms[$p];
    }
}

$t = new T();
$replace = "['data1','Hi there'],['data2','Hello there']";  
$aParts = explode('],[', trim($replace, ']['));
foreach ($aParts AS &$part)
{
    $part = explode("','", trim($part, "'"));
    $t->setParam($part[0], $part[1]);    
}
print_r($t);

Which would give me:

Code:

T Object

(

    [itms:private] => Array

        (

            [data1] => Hi there

            [data2] => Hello there

        )



)

To which I can access using:

Code:

print $t->getParam('data1');

Edit:
Oh, BTW, this is what makes sense:

PHP Code:

$content = "<div>#data1#</div> <div>#data2#</div>"; $string = str_ireplace( "#data1#", "Hi", $content ); $string = str_ireplace( "#data2#", "Hi2", $string );

What I don't understand is how you ever ended up with such a bizarre string like:

PHP Code:

$replace = "['data1','Hi there'],['data2','Hello there']";

If that comes from a database or something else, it would be better to retain it in its array and use the str_[i]replace and give it the arrays instead.

Thankyou!
Worked perfect!
