I am trying to figure out a way using PHP that I can parse a string of data from a URL to separate each entry based on the character |. Example data:
66.85.14.212:7254|108.174.48.186:8340|72.46.152.194:15240|162.248.91.125:7266|91.121.83.48:7619|185.153.228.114:5775|
Anyone got any ideas?
You can use the explode() function to split the string and remove empty elements with array_filter()
$string = '66.85.14.212:7254|108.174.48.186:8340|72.46.152.194:15240|162.248.91.125:7266|91.121.83.48:7619|185.153.228.114:5775|';
$ips = array_filter(explode('|', $string));
which results in an array containing all your ip adresses
Array
(
[0] => 66.85.14.212:7254
[1] => 108.174.48.186:8340
[2] => 72.46.152.194:15240
[3] => 162.248.91.125:7266
[4] => 91.121.83.48:7619
[5] => 185.153.228.114:5775
)
There are also two other functions, split() and preg_split() which supports regular expressions too.

Good day,
I have an I think rather odd question and I also do not really know how to ask this question.
I want to create a string variable that looks like this:
[car]Ford[/car]
[car]Dodge[/car]
[car]Chevrolet[/car]
[car]Corvette[/car]
[motorcycle]Yamaha[/motorcycle]
[motorcycle]Ducati[/motorcycle]
[motorcycle]Gilera[/motorcycle]
[motorcycle]Kawasaki[/motorcycle]
This should be processed and look like:
$variable = array(
'car' => array(
'Ford',
'Dodge',
'Chevrolet',
'Corvette'
),
'motorcycle' => array(
'Yamaha',
'Ducati',
'Gilera',
'Kawasaki'
)
);
Does anyone know how to do this?
And what is it called what I am trying to do?
I want to explode the string into the two arrays. If it is a sub array
or two individual arrays. I do not care. I can always combine the
latter if I wish so.
But from the above mentioned string to two arrays. That is what I
want.
Solution by Dlporter98
<?php
///######## GET THE STRING FILE OR DIRECT INPUT
// $str = file_get_contents('file.txt');
$str = '[car]Ford[/car]
[car]Dodge[/car]
[car]Chevrolet[/car]
[car]Corvette[/car]
[motorcycle]Yamaha[/motorcycle]
[motorcycle]Ducati[/motorcycle]
[motorcycle]Gilera[/motorcycle]
[motorcycle]Kawasaki[/motorcycle]';
$str = explode(PHP_EOL, $str);
$finalArray = [];
foreach($str as $item){
//Use preg_match to capture the pieces of the string we want using a regular expression.
//The first capture will grab the text of the tag itself.
//The second capture will grab the text between the opening and closing tag.
//The resulting captures are placed into the matches array.
preg_match("/\[(.*?)\](.*?)\[/", $item, $matches);
//Build the final array structure.
$finalArray[$matches[1]][] = $matches[2];
}
print_r($finalArray);
?>
This gives me the following array:
Array
(
[car] => Array
(
[0] => Ford
[1] => Dodge
[2] => Chevrolet
[3] => Corvette
)
[motorcycle] => Array
(
[0] => Yamaha
[1] => Ducati
[2] => Gilera
[3] => Kawasaki
)
)
The small change I had to make was:
Change
$finalArray[$matches[1]] = $matches[2]
To:
$finalArray[$matches[1]][] = $matches[2];
Thanks a million!!
There are many ways to convert the information in this string to an associative array.
split the string on the new line into an array using the explode function:
$str = "[car]Ford[/car]
[car]Dodge[/car]
[car]Chevrolet[/car]
[car]Corvette[/car]
[motorcycle]Yamaha[/motorcycle]
[motorcycle]Ducati[/motorcycle]
[motorcycle]Gilera[/motorcycle]
[motorcycle]Kawasaki[/motorcycle]";
$items = explode(PHP_EOL, $str);
At this point each delimited item is now an array entry.
Array
(
[0] => [car]Ford[/car]
[1] => [car]Dodge[/car]
[2] => [car]Chevrolet[/car]
[3] => [car]Corvette[/car]
[4] => [motorcycle]Yamaha[/motorcycle]
[5] => [motorcycle]Ducati[/motorcycle]
[6] => [motorcycle]Gilera[/motorcycle]
[7] => [motorcycle]Kawasaki[/motorcycle]
)
Next, loop over the array and pull out the appropriate pieces needed to build the final associative array using the preg_match function with a regular expression:
$finalArray = [];
foreach($items as $item)
{
//Use preg_match to capture the pieces of the string we want using a regular expression.
//The first capture will grab the text of the tag itself.
//The second capture will grab the text between the opening and closing tag.
//The resulting captures are placed into the matches array.
preg_match("/\[(.*?)\](.*?)\[/", $item, $matches);
//Build the final array structure.
$finalArray[$matches[1]] = $matches[2]
}
The following is an example of what will be found in the matches array for a given iteration of the foreach loop.
Array
(
[0] => [motorcycle]Gilera[
[1] => motorcycle
[2] => Gilera
)
Please note that I use the PHP_EOL constant to explode the initial string. This may not work if the string was pulled from a different operating system than the one you are running this code on. You may need to replace this with the actual end of line characters that is being used by the string.
Why don't you create two separate arrays?
$cars = array("Ford", "Dodge", "Chevrolet", "Corvette");
$motorcycle = array("Yamaha", "Ducati", "Gilera", "Kawasaki");
You could also use an Associative array to do this.
$variable = array("Ford"=>"car", "Yamaha"=>"motorbike");
I have a string like that :
0d(Hi)i(Hello)4d(who)i(where)540d(begin)i(began)
And i want to make it an array with that.
I try first to add separator, in order to use the php function explode.
;0,d(Hi),i(Hello);4,d(who),i(where);540,d(begin),i(began)
It works but the problem is I want to minimize the separator to save disk space.
Therefore i want to know by using preg_split, regular expression, if it's possible to have a huge array like that without using separator :
Array ( [0] => Array ( [0] => 0 [1] => d(hi) [2] => i(Hello) )
[1] => Array ( [0] => 4 [1] => d(who) [2] => i(where) )
[2] => Array ( [0] => 540 [1] => d(begin) [2] => i(began) )
)
I try some code & regex, but I saw that the value in the regular expression was not present in the final result (like explode function, in the final array we do not have the delimitor.)
More over, i have some difficulties to build the regex. Here is the one that I made :
$modif = preg_split("/[0-9]+(d(.+))?(i(.+))?/", $data);
I must precise that d() and i() can not be present (but at least one)
Thanks
If you do
preg_match_all('/(\d+)(d\([^()]*\))?(i\([^()]*\))?/', $subject, $result, PREG_SET_ORDER);
on your original string, then you'll get an array where
$result[$i][0]
contains the ith match (i. e. $result[0][0] would be 0d(Hi)i(Hello)) and where
$result[$i][$c]
contains the cth capturing group of the ith match (i. e. $result[0][1] is 0, $result[0][2] is d(Hi) and $result[0][2] is i(Hello)).
Is that what you wanted?
I get a string that looks like this
<br>
ACCEPT:YES
<br>
SMMD:tv240245ce
<br>
is contained in a variable $_session['result']
I am trying to parse through this string and get the following either in an array or as separate variables
ACCEPT:YES
tv240245ce
I first tried
to explode the string using as the delimiter, and that did not work
then I already tried
$yes = explode(":", strip_tags($_SESSION['result']));
echo print_r($yes);
which gives me an array like so
Array ( [0] => ACCEPT [1] => YESSEED [2] => tv240245ce ) 1
which gives me one of my answers.
Please what would be a great way of trying to achieve what I am trying to achieve?
is there a way to get rid of the first and last?
then use the remaining one as a delimiter to explode the string ?
or what's the best way to go about this ?
This will do it:
$data=preg_split('/\s?<br>\s?/', str_replace('SMMD:','',$data), NULL, PREG_SPLIT_NO_EMPTY);
See example here:
CodePad
You can also skip caring about the spurious <br> and treat the whole string as key:value format with a simple regex like:
preg_match_all('/^(\w+):(.*)/', $text, $result, PREG_SET_ORDER);
This requires that you really have line breaks in it though. Gives you a $result list which is easy to convert into an associative array afterwards:
[0] => Array
(
[0] => ACCEPT:YES
[1] => ACCEPT
[2] => YES
)
[1] => Array
(
[0] => SMMD:tv240245ce
[1] => SMMD
[2] => tv240245ce
)
First, do a str_replace to remove all instances of "SMMD:". Then, Explode on "< b r >\n". Sorry for weird spaced, it was encoding the line break.
Include the new line character and you should get the array you want:
$mystr = str_replace( 'SMMD:', '', $mystr );
$res_array = explode( "<br>\n", $mystr );
Im implementing a profanity filter by using a Trie data structure. Every swear word is added to the Trie. When I have a string to remove profanities from, I explode the string by using punctuations and check every word with the Trie. If found I replace by asterisks.Then I implode the string The issue is, how do I keep track of punctuations? In other words how do I make sure the resultant string has punctuations?
If you are using preg_split() to split up your string, consider using the PREG_SPLIT_DELIM_CAPTURE flag to capture the punctuation with the matches.
Consider:
$str = "This. string/ has? punctuation!";
print_r(preg_split('/(\W+)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE));
/*
Array
(
[0] => This
[1] => .
[2] => string
[3] => /
[4] => has
[5] => ?
[6] => punctuation
[7] => !
[8] =>
)
*/
See http://php.net/preg_split for more information.
Right now i'm trying to get this:
Array
(
[0] => hello
[1] =>
[2] => goodbye
)
Where index 1 is the empty string.
$toBeSplit= 'hello,,goodbye';
$textSplitted = preg_split('/[,]+/', $toBeSplit, -1);
$textSplitted looks like this:
Array
(
[0] => hello
[1] => goodbye
)
I'm using PHP 5.3.2
[,]+ means one or more comma characters while as much as possible is matched. Use just /,/ and it works:
$textSplitted = preg_split('/,/', $toBeSplit, -1);
But you don’t even need regular expression:
$textSplitted = explode(',', $toBeSplit);
How about this:
$textSplitted = preg_split('/,/', $toBeSplit, -1);
Your split regex was grabbing all the commas, not just one.
Your pattern splits the text using a sequence of commas as separator (its syntax also isn't perfect, as you're using a character class for no reason), so two (or two hundred) commas count just as one.
Anyway, since your just using a literal character as separator, use explode():
$str = 'hello,,goodbye';
print_r(explode(',', $str));
output:
Array
(
[0] => hello
[1] =>
[2] => goodbye
)
