foreach simple question

[robert_gsfame]

How can i put foreach result in a string, so let say i have 1 2 3 and separated with ";" so it goes 1;2;3 and i want to put it as $value...how to do??

 

foreach($val as $indeks)

$choice="";

for($i=0;$i<count($val);$i++){

$choice=$choice.$val[$i].";";

}

echo $choice;

 

this give me wrong result..

First off, you are assigning $indeks to equal the current $val, but then you use $val.

 

foreach ($indeks as $val)
{
   $choice="";

   for ($i=0; $i<count($val); $i++) {
      $choice=$choice.$val[$i].";";
   }

   echo $choice;
}

 

This may not work, but you did not show the entire relevant code. Having the for loop in the for loop doesn't make sense for what you asked for.

 

Also, indent code and add spacing accordingly.

sorry..actually i have this one

$val1=explode(";",$_GET['val1']);

$countval2=count($val1);

$val2=explode(";",$_GET['val2']);

$countval2=count($val2);

$value=array_diff($val1,$val2);

 

n i wish to put the difference result in a string called $choice

Have you ever read up on coding practices? Read up here. It's only three pages, and everyone who has to read your code will love you for it.

 

Now, back to your question.

 

What I have so far for you is,

$val1=explode(";",$_GET['val1']);
$countval2=count($val1);
$val2=explode(";",$_GET['val2']);
$countval2=count($val2);
$value=array_diff($val1,$val2);

foreach ($value as $val) {
   $choice="";
   for ($i=0; $i<count($val); $i++) {
      $choice=$choice.$val[$i].";";
   }

   echo $choice;
}

 

After coding standards, I have changed it to look like this:

$val1      = explode(";",$_GET['val1']);
// This next line has no use right now
$countVal1 = count($val1);
$val2      = explode(";",$_GET['val2']);
// This next line has no use right now
$countVal2 = count($val2);
$value     = array_diff($val1 ,$val2);

foreach ($value as $val) {
   $choice="";
   for ($i=0; $i<count($val); $i++) {
      $choice=$choice.$val[$i].";";
   }

   echo $choice;
}

 

Now, other than that, I am very confused about what you want versus what you have. Please describe what you want in a little bit more detail.

maxudaskin, i am still new to PHP n still try to improve my knowledge...what is zend framework actually used for?

 

 

 

[maxudaskin]

It is in essence, the equivalent to a user made addon for a game. It is functions and classes that assist you in creating code. An extension to PHP.
