Insert Into Middle of Array

[xProteuSx]

HELP!!!  PLEASE!!!

 

Here's what's happening:

 

I have a string much like this one:

 

$str = "84,390961CPK_100,'Pink Coloured Cord',15,'390961CPK_100',1";

 

I need to insert apostrophes around the first instance of 390961CPK_100 so it reads '390961CPK_100' and not simply 390961CPK_100.

 

To do this I have made the string into an array as follows:

 

$str_array = str_split($str);

 

Now I need to insert quotes into the array of characters, then convert the whole mess into back into a string.  I can't go by hard coded index numbers, because all of the text in this string is variable in length, so I have to go by the first and second positions of the commas.

 

I have no idea how to do this, and it needs to be done yesterday!  Mucho Gracias to anyone who can help me with this.

You would use explode to break the string into an array at the commas. Then you can easily alter just the second element. Then use implode to put the string back together.

other alternative could be use str_replace()

$str2 = str_replace(",390961CPK_100",",'39091CPK_100'", $str);

Thank you so much guys!  I totally forgot about explode and implode (no, I don't work with arrays very often).

 

If anyone is interested, here is what I came up with:

 

$str = "84,390961CPK_100,'Pink Coloured Cord',15,'390961CPK_100',1";
$elements = explode(",", $str);
$elements[1] = "'" . $elements[1] . "'";
$str = implode(",", $elements);
echo $str;

 

The output would result in:

 

84,'390961CPK_100','Pink Coloured Cord',15,'390961CPK_100',1

 

Now I don't have to pull the rest of my hair out!  Thanks soooooooo much!
