I am working in PHP using strstr() to remove values which are extracted from a MYSQL db to be outputted to an excel file-
CODE:
If (!strstr($value, '<script>')){
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
$row++;
}
This code excludes the columns that contain a <script> tag. However it shifts the contents of the cells up like so:
=====================================
|Question | Answer |
=====+========+===============+=====|
| Male/female | |
|----+--------+---------------+-----|
| | F |
|----+--------+---------------+-----|
Instead I would like it to skip the rows like so:
=====================================
|Question | Answer |
=====+========+===============+=====|
| | |
|----+--------+---------------+-----|
| Male/female | F |
|----+--------+---------------+-----|
Your code is written so that the row is only incremented if your script tag is not found. However, it sounds like you want to unconditionally increment; if that's the case, then move $row++ to outside the if statement, like so:
if (!strstr($value, '<script>')){
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
}
$row++;
If this isn't what you were looking for, then please provide a sample input that can be matched to the output, as this would make what you need crystal clear.

I want to update a field on a really huge (1m rows) table. I want to update it from:
+-----------------------------------------------------------+
| ref |
+-----------------------------------------------------------+
| 0001___000000000003616655___IVANTI UK___TEMPLATE MATERIAL |
+-----------------------------------------------------------+
to:
+-------------------------------+
| ref |
+-------------------------------+
| IVANTI UK___TEMPLATE MATERIAL |
+-------------------------------+
So basically its just changing the ref (which is not fixed length) from sid___sku___mfr___pnum to mfr___pnum format.
In PHP I'd do it like so (pseduo code):
list($p['sid'], $p['sku'], $p['mfr'], $p['pnum']) = explode('___', $row['ref']);
$row['ref'] = $p['mfr'] . '___' . $p['pnum'];
Wondering if its possible to do it directly with MySQL with a performant query?
select SUBSTRING_INDEX(ref,'___',-2) from test
0001___000000000003616655___IVANTI UK___TEMPLATE MATERIAL
=>
IVANTI UK___TEMPLATE MATERIAL
https://dev.mysql.com/doc/refman/5.7/en/string-functions.html#function_substring-index
SUBSTRING_INDEX(str,delim,count)
Returns the substring from string str before count occurrences of the
delimiter delim. If count is positive, everything to the left of the
final delimiter (counting from the left) is returned. If count is
negative, everything to the right of the final delimiter (counting
from the right) is returned. SUBSTRING_INDEX() performs a
case-sensitive match when searching for delim.
This is my first time using Box/Spout library. I am using WAMP server.
My question is the following:
require_once('./spout-master/src/Spout/Autoloader/autoload.php');
use Box\Spout\Writer\WriterFactory;
use Box\Spout\Common\Type;
$filePath = 'test.xlsx';
$writer = WriterFactory::create(Type::XLSX);
$writer->openToFile($filePath);
[X]
$writer->addRow(['a'], $style);
$writer->close();
(1)
When I am running above code, I get the following error message:
Warning: rmdir(C:\WINDOWS\TEMP/xlsx560f58d588ceb): Permission denied in
C:\wamp\www\1300.revenue.com.my\public_html\spoutmaster\src\Spout\Common\Helper\FileSystemHelper.php on line 113
What is the errors means and how should I modify it to prevent this error message appeared?
(2) I want to make expected output like below:
But I didn't know how to write it on [X] part. How to write it in order to get the expected output?
It looks like the default temp folder used to generate the XLSX file cannot be deleted. You can verify it by checking the permissions on C:\WINDOWS\TEMP/xlsx560f58d588ceb.
To solve this issue, you can either manually fix the permissions on the temp folder (C:\WINDOWS\TEMP) or use another temporary folder, as specified here: https://github.com/box/spout#using-custom-temporary-folder
Regarding 2), there is no straightforward way to do this whith Spout. Spout does not support merging cells. The only thing you can do is:
| 1 | 2 | | 3 | |
|---|---|---|---|---|
| | A | B | A | B |
|---|---|---|---|---|
Or alternatively (if that makes more sense):
| 1 | 2 | 2 | 3 | 3 |
|---|---|---|---|---|
| 1 | A | B | A | B |
|---|---|---|---|---|
Either way, you'll have to format the rows as shown above: [[1,2,'',3',''], ['', 'A','B','A','B']] or [[1,2,2,3,3], [1, 'A','B','A','B']]
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 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.
