Feed parsing, splitting string - php

Say I have the following:
$cars = "auto1,auto2,auto3,auto4";
If I parse $cars to insert the value in my database, I get a string like "auto1,auto2,auto3,auto4".
I want to split this string when I parse the feed into "auto1, auto2, auto3, auto4" - basically add spaces between words. How can i do it?
Here's how I get values for $cars:
$xml = simplexml_load_file($feed);
foreach( $xml->feedinfo as $feedinfo )
{
$cars = $feedinfo->cars;
[...]
}
Thank you


If you just want to add spaces:
$cars = str_replace(',', ', ', $cars);
But you could also split it into an array of elements:
$cars = explode(',', $cars)

Efficient way to split a string into an array - PHP

What is the best way to split the below $string to get the array $cars in PHP?
$string = '{xa}{y}{z12}{123}{2}{aabb}';
$cars = array("{xa}","{y}","{z12}", "{123}", "{2}", "{aabb}");
I need each array element with brackets eg : {xa}

$string = str_replace("}{","},{",$string);
$x = explode(',',$string);

Populating an array with fields from a string

I have this string that contains the following quote-contained, comma-separated values:
"field","anotherfield","yetanotherfield"
I need to populate an array with the content of these fields, without the quotes.
What I'm currently doing is:
$string = str_replace('"', NULL, $string);
and then
$array = explode(',', $string);
It works, but it breaks when there's a comma inside any field. How can I prevent this?

first, trim " from the start and end of string.
$string = trim('"field","anotherfield","yetanotherfield","other, another"', '"');
and after explode "," between values you need.
$array = explode('","', $string);

To parse entire CSV file into an array you could use str_getcsv function:
$array = array_map( 'str_getcsv', file( 'path-to-file/file.csv' ) );

Convert string to array and perform foreach, codeigniter

I would like some help in converting a string to an array and performing foreach on the array data.
Currently in my view I echo my string <?php echo $p['tags']; ?>
and this gives me the following data news, latest
I would like to do a foreach on this data so that I can wrap the values in
How is this done? What is the best method?

Explode them into an array:
<?php
$all_tags = explode( ',' , $p['tags'] );
foreach ( $all_tags as $one_tag ){
echo '' . $one_tag . '';
}
The explode() function splits the string using a delimiter (in this case the ',' comma) and each item is passed into the array.

I'm not sure I understand what you're asking correctly. Is this what you want?
$var = 'news, lastest';
$tmp = explode(', ', $var);
$result = ''.implode(', ', $tmp).'';
var_dump($result);
// string(42) "news, lastest"

separate with commas

hey there I have this,
$following_user_id .= $row['following_user_id'];
and I get
44443344330
then I use the implode() function and seperate with commans
44,44,33,44,33,0,
but I don't want the last comma on the last number?
Is this possible?

$following_user_ids = array();
//loop this:
$following_user_ids[] = $row['following_user_id'];
$user_ids_string = implode(',',$following_user_ids);

You can split the string into an array of characters, then implode the array.
$array = preg_split('//', $following_user_id, -1, PREG_SPLIT_NO_EMPTY);
echo implode( ',', $array );

Collect your data into an array of strings and use the implode function:
$uids = array();
while($row = mysql_fetch_assoc($result)){
array_push($uids, $row['following_user_id']);
}
$following_user_id = implode(',', $uids);

Check implode: http://php.net/manual/en/function.implode.php
Code example: I'm assuming your using some sort of loop?
$arrUsers = new array();
... your loop code here ...
array_push($arrUsers, $row['following_user_id']);
... end loop code ..
$following_user_id = impload(",", $arrUsers);

Implode should not be inserting a comma at the end of that string there. Are you sure there isn't an empty string at the end of your array sequence?
Either way, to fix the string you have, just get rid of the last character of the string:
$concatUserIds = "44,44,33,44,33,0,";
$concatUserIds = substr($concatUserIds, 0, strlen($concatUserIds) - 1);
Further, if you're not going to be using the non-comma delimited number set, why don't you just add a comma every time you add a user id. That way you don't even have to use the implode function.

This works for me:
<?php
$following_user_id.= $row['following_user_id'];
$following_user_id=preg_replace('/(?<=\d)(?=(\d)+(?!\d))/',',',$following_user_id);
echo $following_user_id."<br>";
?>

Try using arrays, example
<?php
$arr = array();
$arr[] = 'foo';
$arr[] = 'bar';
echo implode(',', $arr);
