PHP: How can I explode a string by commas, but not wheres the commas are within quotes?
(2 answers)
Closed 8 years ago.
I'm trying to figure out how to add double quote between text which separates by a comma.
e.g. I have a string
$string = "starbucks, KFC, McDonalds";
I would like to convert it to
$string = '"starbucks", "KFC", "McDonalds"';
by passing $string to a function. Thanks!
EDIT: For some people who don't get it...
I ran this code
$result = mysql_query('SELECT * FROM test WHERE id= 1');
$result = mysql_fetch_array($result);
echo ' $result['testing']';
This returns the strings I mentioned above...
Firstly, make your string a proper string as what you've supplied isn't. (pointed out by that cutey Fred -ii-).
$string = 'starbucks, KFC, McDonalds';
$parts = explode(', ', $string);
As you can see the explode sets an array $parts with each name option. And the below foreach loops and adds your " around the names.
$d = array();
foreach ($parts as $name) {
$d[] = '"' . $name . '"';
}
$d Returns:
"starbucks", "KFC", "McDonalds"
probably not the quickest way of doing it, but does do as you requested.
As this.lau_ pointed out, its most definitely a duplicate.
And if you want a simple option, go with felipsmartins answer :-)
It should work like a charm:
$parts = split(', ', 'starbucks, KFC, McDonalds');
echo('"' . join('", "', $parts) . '"');
Note: As it has noticed in the comments (thanks, nodeffect), "split" function has been DEPRECATED as of PHP 5.3.0. Use "explode", instead.
Here is the basic function, without any checks (i.e. $arr should be an array in array_map and implode functions, $str should be a string, not an array in explode function):
function get_quoted_string($str) {
// Here you will get an array of words delimited by comma with space
$arr = explode (', ', $str);
// Wrapping each array element with quotes
$arr = array_map(function($x){ return '"'.$x.'"'; }, $arr);
// Returning string delimited by comma with space
return implode(', ', $arr);
}
Came in my mind a really nasty way to do it. explode() on comma, foreach value, value = '"' . $value . '"';, then run implode(), if you need it as a single value.
And you're sure that's not an array? Because that's weird.
But here's a way to do it, I suppose...
$string = "starbucks, KFC, McDonalds";
// Use str_replace to replace each comma with a comma surrounded by double-quotes.
// And then shove a double-quote on the beginning and end
// Remember to escape your double quotes...
$newstring = "\"".str_replace(", ", "\",\"", $string)."\"";

Add quotation marks to comma delimited string in PHP

I have a variable with string value of 'laptop,Bag' and I want it to look like ' "laptop","Bag" 'or "laptop","Bag". How could I do this one? Is there any php function that could get this job done? Any help please.
This would work. It first, explodes the string into an array. And then implodes it with speech marks & finishes up by adding the opening & closing speech mark.
$string = "laptop,bag";
$explode = explode(",", $string);
$implode = '"'.implode('","', $explode).'"';
echo $implode;
Output:
"laptop","bag"
That's what str_replace is for:
$result = '"'.str_replace(',', '","', $str).'"';
This would be very easy to do.
$string = 'laptop,bag';
$items = explode(',', $string);
$newString = '"'.implode('","', $items).'"';
That should turn 'laptop,bag' into "laptop","bag".
Wrapping that in a function would be as simple as this:
function changeString($string) {
$items = explode(',', $string);
$newString = '"'.implode('","', $items).'"';
return $newString;
}
I think you can explode your string as array and loop throw it creating your new string
function create_string($string)
{
$string_array = explode(",", $string);
$new_string = '';
foreach($string_array as $str)
{
$new_string .= '"'.$str.'",';
}
$new_string = substr($new_string,-1);
return $new_string;
}
Now you simply pass your string the function
$string = 'laptop,Bag';
echo create_string($string);
//output "laptop","Bag"
For your specific example, this code would do the trick:
<?php
$string = 'laptop,bag';
$new_string = ' "' . str_replace(',', '","', $string) . '" ';
// $new_string: "laptop","bag"
?>
That code would also work if you had more items in that list, as long as they are comma-separated.
Use preg_replace():
$input_lines="laptop,bag";
echo preg_replace("/(\w+)/", '"$1"', $input_lines);
Output:
'"laptop","Bag"'
I think you can perform that using explode in php converting that string in to an array.
$tags = "laptop,bag";
$tagsArray = explode(",", $tags);
echo $tagsArray[0]; // laptop
echo $tagsArray[1]; // bag

How can I split a comma delimited string into an array in PHP?
In a comma delimited string, in php, as such: "1,2,3,4,4,4,5" is it possible to say:
if(!/*4 is in string bla*/){
// add it via the .=
}else{
// do something
}
In arrays you can do in_array(); but this isn't a set of arrays and I don't want to have to convert it to an array ....
Try exploding it into an array before searching:
$str = "1,2,3,4,4,4,5";
$exploded = explode(",", $str);
if(in_array($number, $exploded)){
echo 'In array!';
}
You can also replace numbers and modify the array before "sticking it back together" with implode:
$strAgain = implode(",", $exploded);
You could do this with regex:
$re = '/(^|,)' + preg_quote($your_number) + '(,|$)/';
if(preg_match($re, $your_string)) {
// ...
}
But that's not exactly the clearest of code; someone else (or even yourself, months later) who had to maintain the code would probably not appreciate having something that's hard to follow. Having it actually be an array would be clearer and more maintainable:
$values = explode(',', $your_string);
if(in_array((str)$number, $values)) {
// ...
}
If you need to turn the array into a string again, you can always use implode():
$new_string = implode(',', $values);
I am exploding an array appending it and then I am imploding the array back. Everything works fine but I got a small doubt. Please take the example below.
$x = "123,456,789"
explode (' ', $x);
$x[] = "987";
implode (',', $x);
The output looks like the following :
,123,456,789,987
The problem is that the comma appears before the values. I want them to appear after just like the following
123,456,789,987,
You're exploding on a blank space instead of a comma:
explode (' ', $x);
should be
explode (',', $x);
$x = '123,456,789'; // use ' instead " (just for performance)
$x = explode (',', $x);
$x[] = '987';
$y = implode (',', $x);
echo $y . ','; // add trailing comma (what nickb said)
// output:
123,456,789,987,
About the single vs double quotes issue please refers to PHP strings and Is there a performance benefit single quote vs double quote in php?
I've gone through this address:
Passing an array to a query using a WHERE clause
and found that if I use a join clause to separate values , is also at the end of the array. How can I remove last?
I am using like this
$ttst=array();
$ttst=array();
$tt = "SELECT frd_id FROM network WHERE mem_id='$userId'";
$appLdone = execute_query($tt, true, "select");
foreach($appLdone as $kk=>$applist){
$ttst[] = $applist['frd_id'];
}
$result = implode(',', $ttst);
then also coming last ,
Thanks.
but it doesn't give single quote to each value .
join(',', array_filter($galleries))
array_filter gets rid of empty elements that you seem to have. Of course, you should take care not to have empty elements in there in the first place.
You could use trim() (or rtrim()):
$myStr = 'planes,trains,automobiles,';
$myStr = trim($myStr, ',');
$str = "orange,banana,apple,";
$str = rtrim($str,',');
This will result in
$str = "orange,banana,apple";
Update
Based on your situation:
$result = implode(',', $ttst);
$result = rtrim($result,',');
$arr = array(...);
$last = end($arr);
unset($last);
If the trailing "," is an array element of itself, use array_pop(), else, use rtrim()
$array = array('one','two',3,',');
array_pop($array);
print_r($array);
Gives:
Array ( [0] => one 1 => two 2 => 3
)
No need for length. Just take from beginning to the (last character - 1)
$finalResult = $str = substr($result, 0, -1);
Use implode() instead! See Example #1 here http://php.net/manual/en/function.implode.php
Edit:
I think a quick fix would be (broken down in steps):
$temp = rtrim(implode(',', $ttst), ','); //trim last comma caused by last empty value
$temp2 = "'"; //starting quote
$temp2 .= str_replace(",", "','", $temp); //quotes around commas
$temp2 .= "'"; //ending quote
$result = $temp2; // = 'apples','bananas','oranges'
This should give you single-quote around the strings, but note that if some more values in the array are sometimes empty you will probably have to write a foreach loop and build the string.
I have a search box that can contain multiple values using a comma, eg Pasta, tuna, eggs
Im using FULLTEXT mysql search but I need to use some kind of preg_replace to turn Pasta, tuna, eggs into 'Pasta','tuna','eggs'
If I enter this 'Pasta','tuna','eggs' into the search box the results are correct.
Don't use regular expressions for problems that can be solved otherwise. What you want is a simple string replacement:
$string = "'" . str_replace(",", "','", $string) . "'";
You should escape quotes inside the string first, though (don't know what your escape character is, assuming it's backslash):
$string = "'" . str_replace(array("'", ","), array("\\'", "','"), $string) . "'";
Are you building an SQL query with the list? If so, you should take some time to make sure the resulting SQL is properly escaped as well.
$myList = "pasta, tuna, eggs";
$items = preg_split("/[,\\s]+/", $myList);
$sqlItems = array();
foreach ($items as $item) {
$sqlItems[] = "'" . mysql_real_escape_string($item) . "'";
}
// Add new list to SQL
$sql .= implode(",", $sqlItems);
Do you have any comma in values?
If not you could use something like:
preg_replace('/[^,]+/g', '\'\1\'', preg_replace('/\'/g', '\\\'', $text))
implode your string, then foreach resulting array and add needed symbols
Guys sorry for the trouble but I've solved my own question! Ive looked at this and it was all wrong to begin with.
I had to replace each , with a space and a plus sign so ", tuna" = " +tuna"
Thanks anyway
