I have a product that is sold to multiple customers, each customer has its own unique product code derived from the my original product code e.g
My code: 1245-65
Customer 1: 1245/65
Customer 2: 1245.65
My question: Is there any way to analyse such a string and find what is separating its integers? My goal is to have a settings page where a demo customer code would be entered then all product codes would be derived from that example code. I'm sure PHP can handle this!
EXTRA INFO:
Sorry, I haven't given enough information. There might be a situation where the separator is an alphabetical quantity e.g 1245ABC65. I hate updating a question like this when so many people have given valid answers :( my fault.
You can use a regular expression to find the separator.
$str = '1245/65';
preg_match("/\d+(.)\d+/", $str, $separator);
$separator = $separator[1];
You may want to look for non numeric characters using preg_match_all
preg_match_all('/[^0-9]/', '1245-95', $matches);
print_r($matches);
//Array ( [0] => Array ( [0] => - ) ) in the example
With the updated question, you have to write :
$str = '1245ABC65';
preg_match("/\d+([^0-9]+)\d+/", $str, $separator);
echo $separator = $separator[1];
or
preg_match_all('/[^0-9]+/', '1245ABC95', $matches);
print_r($matches);
//Array ( [0] => Array ( [0] => 'ABC' ) ) in the example
Use preg_split and regular expressions, to search for others characters than numbers.
$separador = preg_split ('/\d/', '1234/65', -1, PREG_SPLIT_NO_EMPTY)
$separador = $separador[0];

Am I correct that character precedence would order these like this:
1--2016 name.png, 11--2017 name.png, 2--1999 name.png
Numerically, however, they would be like this:
1--2016 name.png, 2--1999 name.png, 11--2017 name.png
That is, if I'm looking at the first numbers alone. How do you numerically sort an array with strings like this? Namely, integers appended with "--".
It's important to note that these "strings" are actually pathnames which cannot be renamed. See glob for more information.
Edit, after modified question:
After your edit, obviously all answers in this thread are wrong. Also, you don't have to only copy-and-paste a piece of code, but to read entire answer. Sure enough, in my original answer, I say:
if you have a value like “12--3”, it will be sorted like “123”
So, you could see right away that your real case is not coherent with provided sample.
This second solution will sort an array by number at start of given basename path followed by two dashes. It will be applicable on following cases:
String Will be sorted by
------------------------------ -----------------
/Absolute/Path/12-- 12
/Absolute/Path/12--2001.png 12
/12--2001.png 12
12--2001.png 12
a12--2001.png a12--2001.png
-12--2001.png -12--2001.png
Having this array:
[
'/path/to/image/1--2016 name.png',
'/path/to/image/11--2017.png',
'/path/to/image/2--1999.png'
]
You can replace regular expression patter of above original solution with this pattern:
~^(.*/)?(\d+)--[^/]*$~
And above array will be sorted in this way:
Array
(
[0] => /path/to/image/1--2016 name.png
[1] => /path/to/image/2--1999.png
[2] => /path/to/image/11--2017.png
)
eval.in demo
Pattern explanation:
~
^ # Start of string
(.*/)? # Group 1 (optional): zero-ore-more characters followed by a slash
(\d+) # Group 2: one-or-more digits
-- # two dashes
[^/]* # zero-or-more characters, except slash
$ # End of string
~

Original answer (for original question):
There are surely many ways to obtain your result. Using usort and preg_replace:
$array = ['11--','23--','1--'];
usort
(
$array,
function( $a, $b )
{
return preg_replace( '~[^\d]~', '', $a ) - preg_replace( '~[^\d]~', '', $b );
}
);
$array now is:
Array
(
[0] => 1--
[1] => 11--
[2] => 23--
)
Above solution will sort your array deleting1 all not digits characters.
So, if you have a value like 12--3, it will be sorted like 123. Consequently, it doesn't work on not-integer or negative numbers.
1 Actually, the original array values are not changed.
If you wanted a quick fix to getting this done, you could:
$strings = array('5--', '2--', '11--');
$newStrings = array();
foreach ($strings as $string) {
$stringNew = str_replace('--', '', $string);
array_push($newStrings, $stringNew);
}
sort($newStrings);
$doneArray = array();
foreach ($newStrings as $newString) {
array_push($doneArray, $newString.'--');
}
// $doneArray is the new array full of the sorted strings.
I didn't really bother with the variable names, but that's a nice way to do it.
natsort
See here.
I'm not sure how glob sorts things as they come in, but I thought that sort would have ordered them correctly, but natsort will do the trick.
I am trying to generate a regex that allows me to do the following:
I have a string containing several terms, all which are alphanumeric and maybe some of these special characters: +.#
They are separated by a comma as well.
This is kind of how it looks like:
$string = 'Term1,Term2,Term3,Term4'; ... And so on... (around 60 terms)
I want to be able to get each term and assign it to a variable, because I want to employ a second Regex to a long string, for example:
$secondString = 'This string may contain some terms, such as Term1, or maybe Term2';
So pretty much I want to be able to check if any of the terms in the first string are present in the second string.
I watched the following tutorial:
https://www.youtube.com/watch?v=EkluES9Rvak
But I just seem to not be able to come up with something.
Thank you so much for your help in advance!
Cheers!
You can use array_intersect function after splitting strings into tokens:
$string = 'Term1,Term2,Term3,Term4';
$secondString = 'This string may contain some terms, such as Term1, or maybe Term2';
$arr1 = explode(',', $string);
$arr2 = preg_split('/[,\h]+/', $secondString);
$arr = array_intersect(array_map('strtolower', $arr1), array_map('strtolower', $arr2));
print_r($arr);
Output:
Array
(
[0] => Term1
[1] => Term2
)
I need help to find out the strings from a text which starts with # and till the next immediate space by preg_match in php
Ex : I want to get #string from this line as separate.
In this example, I need to extract "#string" alone from this line.
Could any body help me to find out the solutions for this.
Thanks in advance!
PHP and Python are not the same in regard to searches. If you've already used a function like strip_tags on your capture, then something like this might work better than the Python example provided in one of the other answers since we can also use look-around assertions.
<?php
$string = <<<EOT
I want to get #string from this line as separate.
In this example, I need to extract "#string" alone from this line.
#maybe the username is at the front.
Or it could be at the end #whynot, right!
dog#cat.com would be an e-mail address and should not match.
EOT;
echo $string."<br>";
preg_match_all('~(?<=[\s])#[^\s.,!?]+~',$string,$matches);
print_r($matches);
?>
Output results
Array
(
[0] => Array
(
[0] => #string
[1] => #maybe
[2] => #whynot
)
)
Update
If you're pulling straight from the HTML stream itself, looking at the Twitter HTML it's formatted like this however:
<s>#</s><b>UserName</b>
So to match a username from the html stream you would match with the following:
<?php
$string = <<<EOT
<s>#</s><b>Nancy</b> what are you on about?
I want to get <s>#</s><b>string</b> from this line as separate. In this example, I need to extract "#string" alone from this line.
<s>#</s><b>maybe</b> the username is at the front.
Or it could be at the end <s>#</s><b>WhyNot</b>, right!
dog#cat.com would be an e-mail address and should not match.
EOT;
$matchpattern = '~(<s>(#)</s><b\>([^<]+)</b>)~';
preg_match_all($matchpattern,$string,$matches);
$users = array();
foreach ($matches[0] as $username){
$cleanUsername = strip_tags($username);
$users[]=$cleanUsername;
}
print_r($users);
Output
Array
(
[0] => #Nancy
[1] => #string
[2] => #maybe
[3] => #WhyNot
)
Just do simply:
preg_match('/#\S+/', $string, $matches);
The result is in $matches[0]
I'm trying to get the 2 values in this string using regex:
a:2:{i:45;s:29:"Program Name 1";i:590;s:19:"Program Name 2";}
There are 2 variables that start with "s:" and end with ":" which I am attempting to get from this string (and similar strings.
$string = 'a:2:{i:45;s:29:"Program Name 1";i:590;s:19:"Program Name 2";}';
preg_match_all("/s:(\d+):/si", $page['perfarray'], $match);
print_r($match);
I have tried numerous things but this is the first time I've attempted to use regex to get multiple values from a string.
This is the current result: Array ( [0] => Array ( ) [1] => Array ( ) )
Any constructive help is greatly appreciated. I have already read the functions on php.net and I can't find a similar question on stack overflow that matches my needs closely enough. Thanks in advance.
That looks like a serialized string. Instead of using a regular expression, use unserialize() to retrieve the required value.
Update: It looks like your string is not a valid serialized string. In that case, you can use a regular expression to get the job done:
$string = 'a:2:{i:45;s:29:"Program Name 1";i:590;s:19:"Program Name 2";}';
if(preg_match_all("/s:(\d+):/si", $string, $matches)) {
print_r($matches[1]);
}
Output:
Array
(
[0] => 29
[1] => 19
)
That should work:
preg_match_all("/s:([0-9]+):/si", $page['perfarray'], $match);
How can I match both (http://[^"]+)'s?:
(I know it's an illegal URL, but same idea)
I want the regex to give me these two matches:
1 http://yoursite.com/goto/http://aredirectURL.com/extraqueries
2 http://aredirectURL.com/extraqueries
Without running multiple preg_match_all's
Really stumped, thanks for any light you can shed.
This regular expression will get you the output you want: ((?:http://[^"]+)(http://[^"]+)). Note the usage of the non-capturing group (?:regex). To read more about non-capturing groups, see Regular Expression Advanced Syntax Reference.
<?php
preg_match_all(
'((?:http://[^"]+)(http://[^"]+))',
'',
$out);
echo "<pre>";
print_r($out);
echo "</pre>";
?>
The above code outputs the following:
Array
(
[0] => Array
(
[0] => http://yoursite.com/goto/http://aredirectURL.com/extraqueries
)
[1] => Array
(
[0] => http://aredirectURL.com/extraqueries
)
)
you can split the string with this function:
http://de.php.net/preg_split
each part can contain e.g. one of the urls in the array given in the result.
if there is more content maybe call the preg_split using a callback operation while your full text is "worked" on.
$str = '';
preg_match("/\"(http:\/\/.*?)(http:\/\/.*?)\"/i", $str, $match);
echo "{$match[0]}{$match[1]}\n";
echo "{$match[1]}\n";
