split( ) in a loop????

BONO

HI,

How can we loop using the split function?

I have a varying number of lines to split.
This doesn't work:

for ($j=0;$j<$number;$j++){

$nomvar = "arrTemp".$j;
$$nomvar=split(" ",$arr[$j]);

echo $$nomvar[$j];

}//finfor

This doesn't work either:

for ($j=0;$j<$number;$j++){

$nomvar[$j]=split(" ",$arr[$j]);

echo $nomvar[$j];

}//finfor

What else can I try?????????????

Thanks

I'm not 100% sure what you are trying to do. However, are you aware that split creates an ARRAY of strings from the string passed to it as an argument?

Therefore,

$nomvar[$j]=split(" ",$arr[$j]);

doesn't seem to make much sense, unless you are aware that at

$nomvar[$j]

you are inserting an array. Multidimensional arrays are cool and stuff, but only as long as you know what you are doing with them.

Tell us why you want to use split in a loop.

HI BDKR,

I'm making a function which needs to split a varying number of strings. That's why I need to loop. Obviously not changing the array name will cause me to "crush" what's already there. Concatenating a variable name ex: $array.$i would have been great here but it doesn't work either. Do you think this would work??

$nomvar[$i][$j]=split(" ",$nomvar[$j]);

if not I'll have to use a loop inside a loop and use something like this once the split is made in my first loop:

for ($i=0;$i<4;$i++){
$arrFinal[$i+$iCpt]=$nomvar[$i];

}

this will assure that I don't crush anything but it's not too elegant.

Thanks

I'm making a function which needs to split a varying number of strings.

Well, I'm still not sure if I'm following you, but how about this.

# An array of strings
$strings  

# An array to hold these arrays
$the_split=array();

foreach($strings as $string)
    {  $the_split[]=split(" ", $string);  }

Now I have no idea how or where you are getting each of these strings that need to be parsed (split) so I made an assumption. That assumption being $strings.

So when the loop has completed, you will have one array called $the_split. Each (and this is VERY important to realize) element of that array is an array of each string inserted into it after being run through the split function. So, as I said earlier, you have a multidimensional array. Run a print_r on it to see it's output.

Going on, is $nomvar and array of strings? If so, why not something like...

foreach($nomvar as $var)
    { $the_split[]=split(" ", $var);  }

What do you mean by 'crush'?

Anyways, if we knew how you are getting these strings, not to mention WHY you need to split (or explode) them, it would help greatly.

Here is the type of structure that I need to parse:

"breakfast: 1 cup milk, 2 large toasts
morning snack: 100 gr granola bar
lunch: 1 can soup, 1 glass milk, 1 small sandwich, 1 large cake"

.... and so on....

so you can see that the number of items can vary

At the end, I need to have one single array that will contain each individual part (to be inserted in a database)
ex:

$arr[0]=1 //quantity
$arr[1]=cup//serving size
$arr[2]=milk//food
$arr[3]=2//quantity
$arr[4]=large //serving size
$arr[5]=toasts //food

........and so on.......

and so you see I need to split with ":" then "," then " "

I hope this helps to understand.
I'll try what you suggested. Thanks

Cheers
