I am working on retriving category values from a wiki markup text in loop, could not grab category values from the markup using regex match in php
The Markup Text Contains the category values as
$input_wiki_markup = "
[[Category:Google]]
[[Category:Tricks]]
[[Category:Google Search]]
[[Category:Filters]]
[[Category:Search]]
[[Category:Tips]]";
Here's what I have tried so far
$matches = array();
if(preg_match("/\[\[(Category):(.+)*\]\]/i", $input_wiki_markup, $matches)){
print_r($matches);
}
This is the output
Array
(
[0] => [[Category:Google]][[Category:Tricks]][[Category:Google Search]][[Category:Filters]][[Category:Search]][[Category:Tips]]
[1] => Category
[2] => Google]][[Category:Tricks]][[Category:Google Search]][[Category:Filters]][[Category:Search]][[Category:Tips
)
But I'm trying to get output array with only category values after colon , i.e.
Array
(
[0] => Google
[1] => Tricks
[2] => Google Searcg
)
And so on.
What changes should i make to my regex to get only category values filled up in the $mathces array
Or should i use oter php function instead of preg_match ?
Kindly note that, the $input_wiki_markup also containes other text around the [[Categpry:xyz]] tags
all you need was an all
$input_wiki_markup="
[[Category:Google]]
[[Category:Tricks]]
[[Category:Google Search]]
[[Category:Filters]]
[[Category:Search]]
[[Category:Tips]]
";
$matches = array();
if(preg_match_all("/\[\[(Category):(.+)*\]\]/i", $input_wiki_markup, $matches)){
print_r($matches);
}
OUTPUT:
Array
(
[0] => Array
(
[0] => [[Category:Google]]
[1] => [[Category:Tricks]]
[2] => [[Category:Google Search]]
[3] => [[Category:Filters]]
[4] => [[Category:Search]]
[5] => [[Category:Tips]]
)
[1] => Array
(
[0] => Category
[1] => Category
[2] => Category
[3] => Category
[4] => Category
[5] => Category
)
[2] => Array
(
[0] => Google
[1] => Tricks
[2] => Google Search
[3] => Filters
[4] => Search
[5] => Tips
)

I need help figuring out what I am doing wrong and/or if there is a better way to do it, my question is two part. The first part is I am using Joomla 3.5.1 and in the template I have two fieldsets, one that allows the user to enter links to their social media accounts and the second I am attempting to make a sort if you will using a set of drop downs. This may or may not be the best so I am open to options here.
Now for the second part. I am able to bring in the both field sets into separate arrays, for simplicity array 1 and array 2. Array 1 has the links and array 2 has the order. So my question is this, how would be the best way to loop through and match everything up while removing the empties in array 1 and "none" in array 2.
One thought I did have is should array 2 not be multidimensional and let the key be the "soXYZ", but then how would the best way to match it up knowing that the lengths are different and the order as well.
Array 2 where (-1) are "None" in the drop downs
Array

[0] => soPhone
[1] => soContact
[2] => soFacebook
[3] => soMap
[4] => -1

Any guidance is appreciated.
After the power of posting I was able to eventually get my desired result, which as follows:
I set up three arrays arrLinks (originally Array 1) , arrLinksOrder (originally Array 2) and arrLinksCombined (Array Result), then populated arrLinks with the user entered text links on the template, arrLinksOrder pulls from the drop downs.
My original plan was to have arrLinks be multidimensional but in the end I just set the key's for each in my code.
I then used this stackoverflow link to help combine the arrLinksOrder and arrLinks. Once everything is combined I was able to build the html and really clean up the file to something easier to manage.
Code below:
// Populate the contents of the text-box into an array
$arrLinks = array(
"soFacebook"=> $tbFacebook,
"soTwitter"=> $tbTwitter,
"soGoogle"=> $tbGoogle,
"soLinkedIn"=> $tbLinkedIn,
"soPinterest"=> $tbPinterest,
"soYouTube"=> $tbYouTube,
"soInstagram"=> $tbInstagram,
);
// Populate an array (arrLinksOrder) with the drop down selections
for ($i=1; $i < ($linksCount+1); $i++) {
$varName = 'listSocialOrder'.$i;
$arrLinksOrder[$i] = $$varName;
}
// Combine arrLinksOrder and arrLinks, if the arrLinksOrder exists in arrLinks
foreach($arrLinksOrder as $key) {
if(array_key_exists($key, $arrLinks)) {
$arrLinksCombined[$key] = $arrLinks[$key];
}
}
If anyone has any improvements please feel free to share, this is what worked for me at the time.
I call again THIS function so I get some new $key is this and i want to add it to same array so I can check if it is same so unique it. Some thing like global array.
function getNodesInfo($node)
{
foreach ($result as $key => $value)
{
$items[]=$key;
}
echo ("-----."\n");
print_r($items."\n");
getNodesInfo($subNode);
}
It is my output
-------
Array
(
[0] => author
[1] => title
[2] => genre
[3] => price
[4] => publish_date
[5] => description
)
-------
Array
(
[0] => author
[1] => title
[2] => genre
[3] => price
[4] => publish_date
[5] => description
)
-------
Array
(
[0] => book
)
and I want my output looklike
Array
(
[0] => author
[1] => title
[2] => genre
[3] => price
[4] => publish_date
[5] => description
)
-------
Array
(
[0] => book
)
Use the below Algorithm for this.
Step 1 : Create a Blank array.
Step 2 : Each time when you get an array with data, Check whether that array exists in the Blank array or not.
Step 3 : If it does not exist, Add that array(with data) to Blank array. If it exists Do not add that array just discard it.
At the end you will get the unique values inside Blank array which you have created. It is a simple process
I need to parse some data from a text and so i copy/pasted it into an array and used it like this:
$array = array("_alpha","_beta","_gama","_delta","_epsilon");
foreach ($array as $key => $value) {
{use the value in my script bellow....}
}
The data was coming from a script that had private declarations on the top of the file looked like this, so it was easy to just copy/paste it.
$private = ["_alpha","_beta","_gama","_delta","_epsilon"];
Now i had to parse many files so i tried to gather that $array data as best as i could into one array, so i can parse it using the same function...Well the best i could come out with is this:
Array
(
[0] => "_alpha","_delta","_beta","_epsilon","_delta","_kapa",
[1] => "_beta","_alpha","_delta","_kapa","_lamda","_epsilon","_array","_alpha"
[2] => "_epsilon","_array","_alpha","_theta","_omega"
[3] => "_alpha"
[4] => "_kapa","_lamda","_epsilon"
[5] => "_beta","_epsilon","_delta","_kapa","_lamda"
[6] => "_omega","_omega","_delta"
....
....
}
Each line represents the header from a file. Note the quotes around the values...
How can i make the above look like this:
Array
(
[0] => _alpha
[1] => _beta
[2] => _gama
[3] => _delta
[4] => _epsilon
...
...
..
)
Each value on its own, and without the quote or commas etc....just a plain value.
I can also extract the data in this format..but i think thats harder to do:
Array
(
[0] => Array
(
[0] => "_alpha"
[1] => "_beta"
[2] => "_gama"
[3] => "_delta"
[4] => "_epsilon"
...
...
..
)
[1] => Array
(
[0] => "_alpha"
[1] => "_beta"
[2] => "_gama"
[3] => "_delta"
[4] => "_epsilon"
[5] => "_epsilon"
...
..
)
...... etc etc ......
[10] => Array
(
[0] => "_alpha"
[1] => "_delta"
[2] => "_omega"
)
}
_Thanks
$private = ["_alpha","_beta","_gama","_delta","_epsilon"];
print_r($private);
Array
(
[0] => _alpha
[1] => _beta
[2] => _gama
[3] => _delta
[4] => _epsilon
)
i dont know whats the problem
but when i use your codes everything works fine
I am trying to preg_match a url consisting of a category slug, an optional subcategory slug and an option item slug.
It works in all cases, except for the 4th case.
$urls[0] = '/main_cat_slug';
$urls[1] = '/main_cat_slug/';
$urls[2] = '/main_cat_slug/sub_cat_slug';
$urls[3] = '/main_cat_slug/sub_cat_slug/';
$urls[4] = '/main_cat_slug/item.html';
$urls[5] = '/main_cat_slug/sub_cat_slug/item.html';
$regexp = array();
$regexp[] = '/(?:(?<category>[\w]+)/?)'; // Find the main category (is always available)
$regexp[] = '(?:(?<subcategory>[\w]+)/?)?'; // Find an optional sub-category, is not always available
$regexp[] = '(?:(?<item>[\w]+)\.html)?'; // Find an optional item, is not always available (don't catch the extension)
$regexp = implode('', $regexp);
foreach($urls as $index=>$url) {
preg_match("#{$regexp}#i", $url, $matches);
echo '<pre><h1>', $index, '</h1>';
echo $url, '<br />';
echo '<br />';
print_r($matches);
}
In the 4-th case, the category will be found, but the item is empty and the subcategory gets the value op "item".
Could someone help me out, so that the 4-th case will only get a category and an item?
This is the output for above code:
0
/main_cat_slug
Array
(
[0] => /main_cat_slug
[category] => main_cat_slug
[1] => main_cat_slug
)
1
/main_cat_slug/
Array
(
[0] => /main_cat_slug/
[category] => main_cat_slug
[1] => main_cat_slug
)
2
/main_cat_slug/sub_cat_slug
Array
(
[0] => /main_cat_slug/sub_cat_slug
[category] => main_cat_slug
[1] => main_cat_slug
[subcategory] => sub_cat_slug
[2] => sub_cat_slug
)
3
/main_cat_slug/sub_cat_slug/
Array
(
[0] => /main_cat_slug/sub_cat_slug/
[category] => main_cat_slug
[1] => main_cat_slug
[subcategory] => sub_cat_slug
[2] => sub_cat_slug
)
4
/main_cat_slug/item.html
Array
(
[0] => /main_cat_slug/item
[category] => main_cat_slug
[1] => main_cat_slug
[subcategory] => item
[2] => item
)
5
/main_cat_slug/sub_cat_slug/item.html
Array
(
[0] => /main_cat_slug/sub_cat_slug/item.html
[category] => main_cat_slug
[1] => main_cat_slug
[subcategory] => sub_cat_slug
[2] => sub_cat_slug
[item] => item
[3] => item
)
Kind regards!

Description
This regex will pickout the three types of data, using the following rules:
The / is always the first character in the string
The Main_Cat is always first, it follows the first / and continues until the next /
If the first string ends in .html/ then this is a Main_Cat
if the first string ends in .html followed by the end of the string, then this is an item
The Sub_Cat is always second, it follows the second / and continues until the next /
If the second string ends in .html/ then this is a Sub_Cat
if the second string ends in .html followed by the end of the string, then this is an item
The Item type always has an .html suffix
There will never be a / after the Item
the Item type will always be the last field
^\/(?:(?<Main_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Sub_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Item>[^\/\r\n]*?)(?:\.html|$))?
If you're using this expression against individual strings then you can remove the new line characters \r\n. The resulting expression would look like: ^\/(?<Main_Cat>[^\/]*)(?:(?:\/(?![^\/]*\.html)(?<Sub_Cat>[^\/]*))?(?:\/(?<Item>[^\/]*)\.html)?)?.*?$ follows the same rules above. Note the end of line $ forces the test to match your entire string
PHP Code Example:
Source String
/category0.html/subcat/item.html
/item1.html
/category2.html/subcat2.html/item2.html
/category3.html/subcat3.html/
/category4.html/item4.html
/main_cat_slug5.html/
/main_cat_slug6/item6
/main_cat_slug7/sub_cat_slug7.html/
/main_cat_slug8/item8.html
/main_cat_slug9/sub_cat_slug9/item9.html
Code
<?php
$sourcestring="your source string";
preg_match_all('/^\/(?:(?<Main_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Sub_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Item>[^\/\r\n]*?)(?:\.html|$))?/imx',$sourcestring,$matches);
echo "<pre>".print_r($matches,true);
?>

You can try this:
preg_match('~/(?<main_cat>[^/\s]++/?+)(?<sub_cat>[^/\s]++/?+)?'
. '(?>(?<filename>\S+?)\.html)?~', $url, $match);
print_r($match);
Note that you can access easily to the different parts with the named captures (useful to test if there is a subpattern or not.).
I have this list of urls:
http://test1.google.com/test1/12345http://test2.google.com/test2/12345http://test3.google.com/test4/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345
It's just an example, I want to preg_match_all a list of valid urls that doesn't have space to seperate between them, so, I will get it in an array and each cell is different url.
No need for preg_match IMHO:
<?php
$links = 'http://test1.google.com/test1/12345http://test2.google.com/test2/12345http://test3.google.com/test4/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345http://test1.google.com/test1/12345';
$links = array_map(function($chunk){return 'http://'.$chunk;}, explode('http://', $links));
array_shift($links);
print_r($links);
Demo, Output:
Array
(
[0] => http://test1.google.com/test1/12345
[1] => http://test2.google.com/test2/12345
[2] => http://test3.google.com/test4/12345
