String to array?

ziycon · #1 (**permalink**) 17-01-2008, 11:40 AM

I'm currently taking a string from the DB like this ;1|;3|;7| and im changing it to 1 3 7, but the way i'm doing it wont allow for my to use any number above 9 as they are double digits!
Is there any way to take a string like 1 4 7 10 and put it into an array and remove the whitespace so in array element 0 i have 1 in array element 1 id have 4 etc?

if you use split function it should work

PHP Code:

  $str = preg_replace("#[^0-9|]+#","",$str);
$arr_str = split('|', $str);

if you show us the code you have we might be able to help better.

Currently i'm using this function call:

PHP Code:

  display_proper_format(display_platform_format(";1|;4|;7|;10|"));

and these are the methods:

PHP Code:

  function display_platform_format($format)
{
    $format = str_replace(";","",$format);
    $format = str_replace("|"," ",$format);
    return $format;
}
function display_proper_format($formats)
{
    $size = strlen($formats);
    $number = $size / 2;
    $count = 0;
    $i = 1;
    while($number > $count)
    {
        $item = $i;
        if($item == 1)
        {$format = "Windows";}
        else if($item == 2)
        {$format .= " Unix";}
        ...
        $count++;
        $i += 2;
    }
    
    return $format;
}

did you try the solution I gave you above?

you should leave the "|" so you can use it as a pointer for the split function.

A split function would do this perfect. Haven't done it in php but I do in asp all the time and it's exactly what you want.

As david said ...

$data = ";1|;3|;7| ";
$array = split('[;|]', $data);

Can't get this to work, any help me???

PHP Code:

  function display_proper_format($formats)
{
    $formats = ";1|;3|;7| ";
    $array = split('[;|]', $formats);
    $i = 0;
    $count = sizeof($array);
    while($i < $count)
    {
        $item = $array[$i];
        if($item == 1)
        {$format = "PC";}
        else if($item == 2)
        {$format .= " Xbox";}
        else if($item == 3)
        {$format .= " Xbox360";}
        else if($item == 4)
        {$format .= " PS2";}
        else if($item == 5)
        {$format .= " PS3";}
        else if($item == 6)
        {$format .= " PSP";}
        else if($item == 7)
        {$format .= " GC";}
        else if($item == 8)
        {$format .= " Wii";}
        else if($item == 9)
        {$format .= " DS";}
        else if($item == 10)

        $i++;
    }
    
    return $format;
}

works semi fine for me ...

though you are passing in $format to it .. and then defining format in the first line ?

Forbairt · #10 (**permalink**) 27-01-2008, 07:02 PM

BTW I should add I don't like what you're doing in your code

Code:

$format[1]  = "PC";
$format[2]  = "Xbox";
$format[3]  = "Xbox360";
$format[4]  = "PS2";
$format[5]  = "PS3";
$format[6]  = "PSP";
$format[7]  = "GC";
$format[8]  = "Wii";
$format[9]  = "DS";
$format[10] = "GBA";   

$formats = ";1|;3|;7|";

$string = "";
preg_match_all("/(\d+)/",$formats,$matches);
$items=$matches[1];
sort($items);

foreach($items as $console)
{
  $string .= $format[$console]." "; 
}
chop($string);

echo $string;

Multiple if statements like that are really a no no
