I have some raw data like this
\u002522\u00253A\u002522https\u00253A\u00255C\u00252F\u00255C\
My intention is to remove the backslash "\" and first 7 digit of every string between \u002522https\ this. For this the output will be only https.
If there is only 7 digit like this \u002522\ the output will be empty.
My final intention is to put every result in a array which is formatted for the above raw data like this
Array
(
[0] =>
[1] =>
[2] => https
[3] =>
[4] =>
[5] =>
[6] =>
)
I want this result for constructing a URL. I have tried with preg_replace and explode function to get my expected result but I am failed.
$text = '\u002522\u00253A\u002522https\u00253A\u00255C\u00252F\u00255C\\';
$text = preg_replace("#(\\\\[a-z0-9]{7})#is",",",$text);
$text_array = explode(",",trim($text,'\\'));
print_r($text_array);

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.
$variable = array("Ford"=>"car", "Yamaha"=>"motorbike");
I need a regex that match if the array contain certain it could anywhere for example, this array :
Array
(
[1] => Array
(
[0] => http://www.test1.com
[1] => 4
[2] => 4
)
[2] => Array
(
[0] => http://www.test2.fr/blabla.html
[1] => 2
[2] => 2
)
[3] => Array
(
[0] => http://www.stuff.com/admin/index.php
[1] => 2
[2] => 2
)
[4] => Array
(
[0] => http://www.test3.com/blabla/bla.html
[1] => 2
[2] => 2
)
[5] => Array
(
[0] => http://www.stuff.com/bla.html
[1] => 2
[2] => 2
)
I want to return all but the array that have the word stuff in it, and when i try to test with this it doesn't quite work :
return !preg_match('/(stuff)$/i', $element[0]);
any solution for that ?
Thanks
You don't need a regular expression for performing a simple search. Use array_filter() in conjunction with strpos():
$result = array_filter($array, function ($elem) {
return (strpos($elem[0], 'stuff') !== FALSE);
});
Now, to answer your question, your current regex pattern will only match strings that contain stuff at the end of the line. You don't want that, so get rid of the "end of the line" anchor $ from your regex.
The updated regex should look like below:
return !preg_match('/stuff/i', $element[0]);
If the actual use-case is different from what is shown in your question and if the operation involves more than just a simple pattern matching, then preg_match() is the right tool. As shown above, this can be used with array_filter() to create a new array that satisifes your requirements.
Here's how you'd do it with a callback function:
$result = array_filter($array, function ($elem) {
return preg_match('/stuff/i', $elem[0]);
});
Note: The actual regex might be more complex - I've used /stuff/ as an example. Also, note that I've removed the negation !... from the statement.
Your pattern will only match a string where stuff appears at the end of the string or line. To fix this, just get rid of the end anchor ($):
return !preg_match('/stuff/i', $element[0]);
I have a problem with str_getcsv function for PHP.
I have this code:
<?php
$string = '#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=714000,RESOLUTION=640x480,CODECS="avc1.77.30, mp4a.40.34"';
$array = str_getcsv($string, ",", '"');
print_r($array);
Which should return:
Array
(
[0] => #EXT-X-STREAM-INF:PROGRAM-ID=1
[1] => BANDWIDTH=714000
[2] => RESOLUTION=640x480
[3] => CODECS=avc1.77.30, mp4a.40.34
)
But instead, it is returning:
Array
(
[0] => #EXT-X-STREAM-INF:PROGRAM-ID=1
[1] => BANDWIDTH=714000
[2] => RESOLUTION=640x480
[3] => CODECS="avc1.77.30
[4] => mp4a.40.34"
)
Cause it is ignoring the enclosure of the last parameter: CODECS and is spliting also that information. I'm using str_getcsv instead of just doing explode(",", $string) precisely for that reason (that function should respect the enclosure) but it is working the same as explode will do it.
The code being executed: http://eval.in/17471
The enclosure (third) parameter does not have quite that effect. The enclosure character is treated as such only when it appears next to the delimiter.
To get your desired output, the input would need to be
#EXT-X-STREAM-INF:PROGRAM-ID=1,...,"CODECS=avc1.77.30, mp4a.40.34"
See it in action.
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?
