Finding the 2nd, 3rd, 4th etc. phrase in a comma-separated array?

[huongtranbong]

If I have an array with:

phrase 1, phrase 2, phrase 3, phrase 4

How do I split it up to have them retrieved individually? I can get phrase 1 okay by searching for the first comma and cutting. But what about the rest?

%%phrase1%% = phrase 1
%%phrase2%% = phrase 2
%%phrase3%% = phrase 3
%%phrase4%% = phrase 4

Help please!

Thanks

If I have an array

If you already have "an array" then they are already "split up" and easily retrievable. So, I guess you don't actually have an array?

I can get phrase 1 okay by searching for the first comma and cutting.

If you have a string where the values are separated by commas (CSV) then you can use the explode() function to convert this string into an array (specifying the comma as delimiter):

$myString = 'phrase 1,phrase 2,phrase 3,phrase 4';
$myValues = explode(',',$myString);

Then reference the elements of the array starting at 0. For example:

echo $myValues[0];
echo $myValues[1];
echo $myValues[2];

However, it looks like the delimiter in your "string" might be comma+space? In which case, specify this as the delimiter to the explode() function. Or use the trim() function when you retrieve these values.

%%phrase1%% = phrase 1 
%%phrase2%% = phrase 2 
%%phrase3%% = phrase 3 
%%phrase4%% = phrase 4 

Not sure what this is refering to? (Some kind of template system?)
