Selecting multiple parts of a split array?

[idire]

Right i had a string, which I split into multiple parts using:

 

$ex = explode(' ', $data);

 

which gives: $ex[0] $ex[1] $ex[2] ... $ex[n]

 

If i wanted to make a new string out of the parts from $ex[2] to $ex[n] how would i do that?

 

e.g. select all the data from a piece onwards.

 

Thanks

I would try something like:

<?php
$ex2[0] = $ex[0]; //Saving the info inside ex[0] optional
$ex2[1] = $ex[1]; //Saving the info inside ex[1] optional
$ex[0] = '';
$ex[1] = '';
$newstring = implode(' ', $ex);
?>

Have a look into array_slice

Ah I guess we learn new things everyday... I didn't know about that function.

What version PHP?

 

When I try

$ex = explode('', $data);

 

I get

Warning: explode() [function.explode]: Empty delimiter. in C:\Inetpub\wwwroot\test\noname2.php on line 3

 

 

 

Can't you just

 

$str = 'abcdefg';
echo substr ($str, 2);        // cdefg

 

If you must use array

 

$str = 'abcdefg';
$ex = str_split($str);                      // put chars in array
echo join ('', array_splice($ex, 2));    // cdefg

Barand, the OP has a space in explodes first parameter.

I should have gone to Specsavers

Just worked it out a different way, this is how i did it:

 

<?php
for($i = 4; $i < count($ex); $i++) { $cmd4 .= $ex[$i] . " "; }
?>

 

Is there anything wrong with this? very inefficient compared to your codes?

[Barand]

it has to count the size each time through the loop and you get an unwanted space at the end.

 

OK, now I know it's a space

 

$str = 'a b c d e f g';
$ex = explode(' ', $str);
echo join (' ', array_splice($ex, 2));    // c d e f g
