So I am creating a website for me and my friends so we can work on projects with each other (Like Google documents), and I am trying to create a thing so we can choose what project we want to work on. Currently I am having trouble getting the names of the projects from the MySQL table.
Here is what I have tried to get the names of the projects
$projects = mysqli_query($link, "SELECT * FROM table WHERE name='". $username ."'");
$projects2 = mysqli_fetch_assoc($projects);
$projects3 = $projects2["projectname"];
And here is an example of the MySQL table
+---------+------------------+------------------+------------------+------------
-+
| name | htmltext | csstext | jstext | projectname
|
+---------+------------------+------------------+------------------+------------
-+
| cow9000 | testing is cool! | testing is cool! | testing is cool! | test
|
| cow9000 | testing is cool! | testing is cool! | testing is cool! | test2
|
+---------+------------------+------------------+------------------+------------
As you can see there are 2 documents that the owner owns, but when I try printing out $project3, it only gives me "test". How would I change my code to get all projectname values?
Sorry if this is confusing, it is hard for me to put it into words. Also, please do point out errors in my code as I only have a couple days of experience in PHP and MySQL (But I am finding that PHP and MySQL is very, very easy for me.)
You already have all of those values. You just access them like you did projectname, by using the name of that column as the key in the $projects2 array:
$projects2 = mysqli_fetch_assoc($projects);
echo $projects2["name"]; // cow9000
echo $projects2["htmltext"]; // testing is cool!
echo $projects2["csstext"]; // testing is cool!
echo $projects2["jstext"]; // testing is cool!
If you want the second row you need to use a loop:
// Prints each row in the order they were retrieved
while($projects2 = mysqli_fetch_assoc($projects)) {
echo $projects2["projectname"]; // test and then test2
}
You have to iterate through the returned data, for example like this:
while ($projects2 = mysqli_fetch_assoc($projects)) {
echo $projects2["projectname"];
}
First it will return test, second test2

I'm trying to get the Sphinx search server working with PDO, but it triggers a syntax error when using the MATCH() function in specific scenarios.
Ex.:
In my code I'm splitting the search query by space and then concatenate it using the | (OR) operator. If someone types test > 3, in the match function it would become (test | > | 3). This combination triggers a: Syntax error or access violation: 1064 main_idx: syntax error, unexpected '|' near ' > | 3'. I don't think it's an escape problem because the > character is not on the escape list and even if you try to escape it, it doesn't work. Is this a bug in the version of Sphinx i'm using? Or am I doing something wrong?
I'm using Sphinx version 2.2.11. It's actually a docker instance provided by this image: jamesrwhite/sphinx-alpine:2.2.11
The PHP version is 7.2.
This is my non-working code:
$searchQuery = "SELECT * FROM main_idx WHERE MATCH(:search)";
$dbh = new PDO('mysql:host=127.0.0.1;port=9306', 'root', 'root');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $dbh->prepare($searchQuery);
$stmt->bindValue('search', 'test | > | 3');
$stmt->execute();
Same code works perfectly fine if I'm using the MySQLi extension. It also works fine with PDO and Sphinx version 2.2.6. Something must've changed between 2.2.6 and 2.2.11. Anyone encountered this issue?
This behaviour is caused by this bug http://sphinxsearch.com/bugs/view.php?id=2305 and this fix https://github.com/sphinxsearch/sphinx/commit/d9923f76c7724fa8d05a3d328e26a664799841b7. In the previous revision ' > | ' was supported.
We at Manticore Search (fork of Sphinx) will check if the fix was correct and will make a better fix if that's not. Thanks for pointing this out.
Meanwhile you can use 2.2.8 from http://sphinxsearch.com/downloads/archive/ or build manually from the latest revision which supports the syntax (https://github.com/sphinxsearch/sphinx/commit/f33fa667fbfd2031ff072354ade4b050649fbd4e)
[UPDATE]
The fix is proper. It was wrong to not show the error about that in the previous versions as long as you DON'T have the spec. character (>) in your charset_table. To workaround this you can add > to your charset_table and then escape it in the search query, e.g.:
mysql> select * from idx_min where match('test | \\> | a');
+------+---------+----------+-------+------+
| id | doc | group_id | color | size |
+------+---------+----------+-------+------+
| 7 | dog > < | 5 | red | 3 |
+------+---------+----------+-------+------+
1 row in set (0.00 sec)
mysql> select * from idx_min where match('test | \\< | a');
+------+---------+----------+-------+------+
| id | doc | group_id | color | size |
+------+---------+----------+-------+------+
| 7 | dog > < | 5 | red | 3 |
+------+---------+----------+-------+------+
1 row in set (0.00 sec)
or
$stmt->bindValue('search', 'test | \\< | a');
in PDO.
There's still a little bug found though which is that if non-spec character is not in charset_table it doesn't generate an error. E.g.
mysql> select * from idx_min where match('test | j | a');
Empty set (0.00 sec)
works fine even though j is not in charset_table. I've filed a bug in our bug tracker https://github.com/manticoresoftware/manticoresearch/issues/156
Thanks again for helping to point this out.
say for exmple you want to do an exact match I like doing my exact matching like this...
...WHERE MATCH(column) AGAINST('happy I am') AND column LIKE '%happy I am%';
that will guarantee I match exactly what I want to match where as if I didn't include the AND LIKE... it would match happy OR I OR am
I have a CakePHP application that uses Fields to store values like 0, 1, 2.
Table:
+----+--------+----------------+
| id | status | title |
+----+--------+----------------+
| 1 | 2 | something new |
| 2 | 1 | nsfw |
| 3 | 1 | a potato |
| 5 | 0 | the real thing |
+----+--------+----------------+
Entity/ Array:
$data = [
0 => 'not published',
1 => 'published',
2 => 'draft',
9 => 'option',
];
// Some public methods to get the data..
Template Form dropdown:
+----+---------------+
| id | value |
+----+---------------+
| 0 | not published |
| 1 | published |
| 2 | draft |
| 9 | option |
+----+---------------+
What I use in template:
echo $this->Form->input('status', ['options' => $article->getArticleStatusList()]);
Example:
articles table with a status field. The default values are: 0 not published, 1 published, etc. Defining those in Entity/Article. There is an array with the default values, so in the template file I call an Entity method that uses the array for the options Form input.
Time ago I was using a configuration array for this.
Is this a good way to accomplish the task? It should be stored in a ini file? Or in a Table/Model?
All works but I want to follow the MVC pattern. Thanks.
Put them in src\Model\ArticleStatus.php. At least for me a status is a list of one or more things that don't change very often. No need to put them in a DB table. These lists are data and clearly belong into the model layer of the MVC pattern.
IMHO it is good practice to use constants for them because you'll do a lot checks in the code against these values. String values are prone to typos and hard to distinguish from other domains. For example if you have two tables using a status of the same name but with a different meaning the code can become tricky to understand and also a search and replace won't work very well because you'll change both types for both domains.
For example we have a countries table with a lot additional info per country but use a list of constants of our ~18 most used countries we have to do conditional checks on because of our business. So we have src\Model\Table\CountriesTable.php but as well src\Model\Country.php. The reason for this is it becomes much much more readable and easier to understand what goes in the the code if you can write Country::GERMANY instead of just using an id like 5. I personally consider it as very bad practice to use hard coded id's everywhere in the code.
if ($country === 41 && $status === 3)
vs
if ($country === Country::GERMANY && $status === ArticleStatus::PUBLISHED)
I think we can agree on that readable and easy to understand code is much better than typing a few characters less. Honestly, people whining about a few characters should learn to type faster. I consider it just as a bad excuse. ;) Also using an IDE will autocomplete the class constants any way for you. It won't do that for an integer.
Here is an example that would even allow you to generate your list with translated labels:
<?php
namespace App\Model;
class ArticleStatus {
const PUBLISHED = 'published';
const DRAFT = 'draft';
// Add more as you like
public static function getStatuses() {
return [
static::PUBLISHED ,
static::DRAFT
];
}
public static function getKeyValueList() {
return [
static::PUBLISHED => __d('app', 'Published'),
static::DRAFT=> __d('app', 'Draft')
];
}
}
Use it in your controller and set it to your view or directly use it in the view.
I have the above table: tblCompInfo, the product_id value is not 100% accurate and I need to fix it. I have total of 543847 total row with 25 different company and 12 different products.
now, The URL is 100% accurate and as you can see from the image I have highlighted with RED which means they are wrong and GREEN which is what it should be updated to.
TASK:
I need to update Product_id by parsing through URL and getting the INTEGER and checking it with product table, if its a product, assign the value else assign 0.
SOLUTION:
I got two solution in my head:
1. EXPORT the entire DATA to EXCEL CVS, change it and UPLOAD it to DATABASE. which means my entire week will be working with EXCEL only.
2. Since I have laravel framework: I can make a function in PHP and get the DATA company wise and UPDATE the table in a foreach loop with condition.
PROBLEM:
So, to make my life easy, I made the PHP function with a simple solution and it works BUT I get MEMORY ALLOCATION PROBLEM.
$companyID = ??;
$tblCompInfos = tblCompInfo::where('company_id', '=', $companyID)->get();
foreach($tblCompInfos as $tblCompInfo)
{
$actual_link = $tblCompInfo->url;
$pathlink = parse_url($actual_link, PHP_URL_PATH);
$product_id_from_url = preg_replace("/[^0-9]/", "" , $pathlink);
$FindIfItsInProductTable = Product::find($product_id_from_url);
$real_product_id = $FindIfItsInProductTable == null ? 0 : $product_id_from_url;
DB::table('tblCompInfo')->where('company_id', '=', $companyID)->where('url', '=', $tblCompInfo->url)->update(array(
'product_id' => $real_product_id,
));
echo $actual_link."-".$real_product_id."=".$tblCompInfo->product_id."<br>";
}
if it was a local server, I would have update my PHP.ini with more memory and do the job.
However, I have a LIVE server and it has to be done in the live server and I have no control or power over PHP.ini.
What to do? How can I do it easily that I will not get a memory issue?
Please help if anyone?
Try this :
UPDATE [table_name] SET product_id = CONVERT(SUBSTR(url, LOCATE('products/', url)+9, LOCATE('/compare',url)-LOCATE('products/', url)+9),UNSIGNED INTEGER)
But this will only works if every url field has suffix as /compare
if you use MariaDB you can use REGEXP_REPLACE to do the changes like
UPDATE your_table
SET url = REGEXP_REPLACE(url,'[0-9]+',Product_id)
WHERE Product_id > 0;
sample
MariaDB [your_schema]> SELECT REGEXP_REPLACE('http://example.com/products/12/compare','[0-9]+','99');
+--------------------------------------------------------------------+
| REGEXP_REPLACE('http://example.com/products/12/compare','[0-9]+','99') |
+--------------------------------------------------------------------+
| http://example.com/products/99/compare |
+--------------------------------------------------------------------+
1 row in set (0.00 sec)
MariaDB [your_schema]>
I have a pretty odd idea but it can work.
Look at that query :
SELECT
'http://example.com/products/12/compare' as url,
'http://example.com/products/' as check1,
'http://example.com/termsets/' as check2,
'http://example.com/products/12/compare' REGEXP 'http://example.com/products/' as regexp_check1, -- check 1
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),1 ) as test1,
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),1 ) REGEXP "^[0-9]+$" as test1_only_num,
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),2 ) as test11,
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),1 ) REGEXP "^[0-9]+$" as test11_only_num,
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),3 ) as test111,
SUBSTRING('http://example.com/products/12/compare', LOCATE('http://example.com/products/','http://example.com/products/12/compare')+LENGTH('http://example.com/products/'),1 ) REGEXP "^[0-9]+$" as test111_only_num;
Result :
+----------------------------------------+------------------------------+------------------------------+---------------+-------+----------------+--------+-----------------+---------+------------------+
| url | check1 | check2 | regexp_check1 | test1 | test1_only_num | test11 | test11_only_num | test111 | test111_only_num |
+----------------------------------------+------------------------------+------------------------------+---------------+-------+----------------+--------+-----------------+---------+------------------+
| http://example.com/products/12/compare | http://example.com/products/ | http://example.com/termsets/ | 1 | 1 | 1 | 12 | 1 | 12/ | 0 |
+----------------------------------------+------------------------------+------------------------------+---------------+-------+----------------+--------+-----------------+---------+------------------+
Url, check1 and check2 are just to display the variables I'm using. It's a main ID, the query is not usable that way of course.
Logic with check1
You check with a REGEX if check1 is present in your URL. If yes, regexp_check1 is 1, else it's 0.
ONLY if regexp_check1 is 1, then you SUBSTRING your URL to take the part that is located AFTER the check1 sentence. You take the first character AFTER (test1), then the two characters AFTER (test11), the three characters AFTER (test111) etc.. until the max length your ID_PRODUCT can be (6 or 7 for example).
You REGEX the SUBSTR you isolated to check if they are numeric only (test1 is numeric, test11 is numeric only, test111 is not numeric only.
Then you know that the content of test11 is your ID
Then you do the same thing with check2 if regexp_check1 was 0, and with an eventual check3 (which would contain http://www.comadso.dk/products/ for example), and for every beginning you can have.
Maybe my idea is a shitty one, but hey if it's seem dumb but works, it's not dumb !
I'm trying to figure out how to use a regex search on a MySQL column to update some data.
The problem is I'm trying to rename part of a URL (i.e a directory).
The table looks something like this (although it's just an example, the actual data is arbitrary):
myTable:
| user_name | URL |
| ------------- |:---------------------------------------------------------:|
| John | http://example.com/path/to/Directory/something/something |
| Jane | http://example.com/path/to/Directory/something/else |
| Jeff | http://example.com/path/to/Directory/something/imgae.jpg |
I need to replace all the URLs that have "path/to/Directory/" to "path/to/anotherDirectory/" while keeping the rest of URL intact.
So the result after the update should look like this:
| user_name | URL |
| ------------- |:----------------------------------------------------------------:|
| John | http://example.com/path/to/anotherDirectory/something/something |
| Jane | http://example.com/path/to/anotherDirectory/something/else |
| Jeff | http://example.com/path/to/anotherDirectory/something/imgae.jpg |
At the moment, the only way I could figure out how to do it is using a combination of regex quires to check for the directory, and then loop over it and change the URL, like this:
$changeArr = $db->query("SELECT URL FROM myTable WHERE URL REGEXP 'path/to/Directory/.+'");
$URLtoChange = "path/to/Directory/";
$replace = "path/to/anotherDirectory/"
foreach ($changeArr as $URL) {
$replace = str_replace($URLtoChange, $replace, $URL);
$db->query("UPDATE myTable SET URL = :newURL WHERE URL = :URL", array("URL"=>$URL,"newURL"=>$replace));
}
This seems to work pretty well, however with such with a big table it can be pretty heavy on performance.
I was wondering if there's a more efficient way to do this? Perhaps with some sort of regex replace in a mySQL query.
Just use the REPLACE() function:
UPDATE myTable
SET URL = REPLACE(url, 'path/to/Directory/', 'path/to/anotherDirectory/')
WHERE URL LIKE '%path/to/Directory/%'
I am trying to run a script through command prompt in PHP and trying to show the result in tabular form. But due to different character length of words I am not able to show the result properly align.
I want result like this
Book ISBN Department
Operating System 101 CS
C 102 CS
java 103 CS
Can anyone please help me to get this output like this in php on console.
Thanks in advance
If you don't want (or not allowed for some reason) to use libraries, you can use standard php printf / sprintf functions.
The problem with them that if you have values with variable and non-limited width, then you will have to decide if long values will be truncated or break table's layout.
First case:
// fixed width
$mask = "|%5.5s |%-30.30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value the end of which will be cut off');
The output is
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value the end of wh | x |
Second case:
// only min-width of cells is set
$mask = "|%5s |%-30s | x |\n";
printf($mask, 'Num', 'Title');
printf($mask, '1', 'A value that fits the cell');
printf($mask, '2', 'A too long value that will brake the table');
And here we get
| Num |Title | x |
| 1 |A value that fits the cell | x |
| 2 |A too long value that will brake the table | x |
If neither of that satisfies your needs and you really need a table with flowing width columns, than you have to calculate maximum width of values in each column. But that is how PEAR::Console_Table exactly works.
You can use PEAR::Console_Table:
Console_Table helps you to display tabular data on a
terminal/shell/console.
Example:
require_once 'Console/Table.php';
$tbl = new Console_Table();
$tbl->setHeaders(array('Language', 'Year'));
$tbl->addRow(array('PHP', 1994));
$tbl->addRow(array('C', 1970));
$tbl->addRow(array('C++', 1983));
echo $tbl->getTable();
Output:
+----------+------+
| Language | Year |
+----------+------+
| PHP | 1994 |
| C | 1970 |
| C++ | 1983 |
+----------+------+
Your best option is to use the Pear Package Console_Table ( http://pear.php.net/package/Console_Table/ ).
To use - on a console you need to install the pear package, running:
pear install Console_Table
this should download the package and install. You can then use a sample script such as:
require_once 'Console/Table.php';
$tbl = new Console_Table();
$tbl->setHeaders(
array('Language', 'Year')
);
$tbl->addRow(array('PHP', 1994));
$tbl->addRow(array('C', 1970));
$tbl->addRow(array('C++', 1983));
echo $tbl->getTable();
You could try the recent simple PHP library ConsoleTable if you don't want to use the standard PHP functions printf/sprintf or the pear package PEAR::Console_Table.
Example:
require_once 'ConsoleTable.php';
$table = new LucidFrame\Console\ConsoleTable();
$table
->addHeader('Language')
->addHeader('Year')
->addRow()
->addColumn('PHP')
->addColumn(1994)
->addRow()
->addColumn('C++')
->addColumn(1983)
->addRow()
->addColumn('C')
->addColumn(1970)
->display()
;
Output:
+----------+------+
| Language | Year |
+----------+------+
| PHP | 1994 |
| C++ | 1983 |
| C | 1970 |
+----------+------+

Too old, but i went trough the same now and used str_pad, just set the lenght as the size of your column and thats it

The CLIFramework table generator helps you get the job done very easily and it supports text alignment, text color, background color, text wrapping, text overflow handling.. etc
Here is the tutorial: https://github.com/c9s/CLIFramework/wiki/Using-Table-Component
Sample code: https://github.com/c9s/CLIFramework/blob/master/example/table.php
use CLIFramework\Component\Table\Table;
$table = new Table;
$table->setHeaders([ 'Published Date', 'Title', 'Description' ]);
$table->addRow(array(
"September 16, 2014",
"Title",
"Description",
29.5
));
$table->addRow(array(
"November 4, 2014",
"Hooked: How to Build Habit-Forming Products",
["Why do some products capture widespread attention whil..."],
99,
));
echo $table->render();
Just in case someone wants to do that in PHP I posted a gist on Github
https://gist.github.com/redestructa/2a7691e7f3ae69ec5161220c99e2d1b3
simply call:
$output = $tablePrinter->printLinesIntoArray($items, ['title', 'chilProp2']);
you may need to adapt the code if you are using a php version older than 7.2
after that call echo or writeLine depending on your environment.
