problem with array value

[Walle]

I have a array like below but I need to remove everything after ; in array values. Is it possible to do somehow?

Array ( [0] => dk [1] => en;q=0.7 [2] => af;q=0.3 )

I need to print like this instead

Array ( [0] => dk [1] => en [2] => af)

Yes, it is possible.
There are the [man]strpos[/man] and [man]substr[/man] functions, for finding the ';' and extracting the bit before it, respectively.
To use that on an array you can either employ a loop ([man]foreach[/man] is pretty straightforward), or if you want to get fancy, write a function that does the job for a single string, and then use [man]array_map[/man] to apply it to an array.

is too much for me as newbie. Isn’t there any simple function for this? Maybe there is better method but I try with this but can’t get it to work

$test=array("se","en;q=0.7","da;q=0.3"); 
foreach ($test as $value) { 

$b = strstr($value, ';', TRUE ); 


  if ($b == "en") 
      { 
         echo "uuuuuuuuuu";
      }

}

If I add "en" in if-statement then echo prints out without everything after it, but if its only "se" for example (in array) and "se" in if-statement, then it not work.

Is it better or easier somehow format that string before make array of that string? What I am try to do is format string from $string = ($_SERVER["HTTP_ACCEPT_LANGUAGE"]);. IE and FF print out like: sv-SE,en;q=0.7,da;q=0.3 if there is more than one language in "browser language list".

You should have a look at those 2 functions
- strpos() ..... find out if one character is in string
- substr()
They are very useful.

Here is a code that will work.

<?php

$test=array("se", "en;q=0.7", "da;q=0.3");

$newarray = array();
foreach ($test as $value) {

$pos = strpos($value, ';'); //find out position of ';'

if($pos !== false){ //was one ';'
    $newarray[] = substr($value, 0, $pos);//from 0 to $pos
}else{              //was not
	$newarray[] = $value;
}	

}

echo '<pre>'.print_r($newarray, true).'</pre>';

?>

That work. This work to but have litle lees code.

<?php 
    $langcode = $_SERVER['HTTP_ACCEPT_LANGUAGE']; 
    if ((strpos(strtolower($langcode), 'se') !== false)) { 
        echo "aaaaaaaa";
    } 
    else { 
        echo "bbbbbbb";
    } 
?>

Problem is now how to use this with file_exists(). I simple want check if file exists with browser code and then include right file. Example check first browser language with first code "se", if there is file match with that code then include("lang/". $browsercode."_lang.php"); and if file not exist the check with next browser code and file. If not mach at all then include en_lang.php

How to do this, do I need some "loop through array" method or something? To match browser language code with file?

[Walle]

$str = strtolower(str_replace('-', '_', $_SERVER['HTTP_ACCEPT_LANGUAGE']));
$str = explode(",",$str);

foreach ($str as $value) { 

$pos = strpos($value, ';'); //find out position of ';' 

if($pos !== false){ //was one ';' 
    $newarray[] = substr($value, 0, $pos);//from 0 to $pos 
}else{              //was not 
    $newarray[] = $value; 
}     

} 

foreach($newarray as $fil) 
{ 
    if(file_exists('lang/' . $fil . '_lang.php'))  

    { 
        echo $fil; 
        break; 
    } 
} 

Can this made better? With lees code, faster etc? It work but I don’t know, something feel wrong to have 2 foreach and 2 if statement.

You're new to programming, aren't you? 🙂

That looks like perfectly reasonable code. It could be done with one loop, but you'd lose so much flexibility you'd probably end up separating them again as soon as you wanted to change anything. For example, if you wanted to respect the quality preferences in the original strings then you'd need to sort the array elements after collecting them but before picking one - in the gap between those two loops, in other words.

Hi Weedpacket,

Really I am, 🙂 I spend days and night with copy and paste, google lots to get some useful to work. Little simple php I have lern but its only some simple variable and some simple if statement.
That code I added with halojoy code I got help with it from a other forum. Without help from friendly people on this and other forum and lots of goggle I will have bigg trouble to do anything useful in php.

Glad to here it looks like perfectly, I needed to know that because I didn’t know if it was OK code to use and feel something was wrong with it. I believe you and if it looks god for you then I believe I can trust this code whiteout have any trouble later with it.

Thanks for help with this, to you and halojoy.
