Then how are managing to query it? How do you check if your query has selected the correct subset? Perhaps this might have been an idea... SELECT * FROM retirees ORDER BY birthday;

That being the case, all you need is $sql = "SELECT .... FROM retirees WHERE CURDATE() = STR_TO_DATE(birthday, '%m/%d/%Y')"; Thank you for keeping that fact hidden (the sample data values you gave us did not reflect the data in the table) and wasting our time.

I can't either. How many retirees do have in your table who were born today (ie 0 years old)

$sql needs to be a string value. Put the query string inside single quotes. $sql = 'SELECT birthday FROM retirees WHERE MONTH(str_to_date(birthday, "%m/%d/%Y")) = MONTH(CURDATE()) AND DAYOFMONTH(str_to_date(birthday, "%m/%d/%Y")) = DAYOFMONTH(CURDATE())';

It will if you tell it to. Put this line mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT); just before your line calling $conn = new mysqli(...)

The output from phpinfo() will tell which php.ini is being used In the php.ini file there will be a line defining the folder where it expects the extensions to be stored Check that is where the new extensions were installed.

Edit your php.ini file and remove the ";" from the start of the lines specifying those extension EG ;extension=mbstring ^ remove Restart your server.

Yes, correct. Although using SELECT * is a bad habit. Select just the columns you need

There are dozens of date functions you can use once you have a date in the correct format. That was just one example. Another couple... SELECT birthday FROM testdate WHERE MONTH(str_to_date(birthday, '%m/%d/%Y')) = 10 AND DAYOFMONTH(str_to_date(birthday, '%m/%d/%Y')) = 22; +------------+ | birthday | +------------+ | 10/22/1989 | +------------+ or, if you want current day's birthdays SELECT birthday FROM testdate WHERE MONTH(str_to_date(birthday, '%m/%d/%Y')) = MONTH(CURDATE()) AND DAYOFMONTH(str_to_date(birthday, '%m/%d/%Y')) = DAYOFMONTH(CURDATE());

Even if don't permanently change the formats, you can still use str_to_date() to make non-standard date formats usable by MySql date/time functions and in date comparison queries. EG SELECT birthday , date_format(str_to_date(birthday, '%m/%d/%Y'), '%W %D %M %Y') as formatted FROM testdate; +------------+---------------------------+ | birthday | formatted | +------------+---------------------------+ | 01/15/1980 | Tuesday 15th January 1980 | | 10/22/1989 | Sunday 22nd October 1989 | | 11/09/1979 | Friday 9th November 1979 | +------------+---------------------------+

You can convert your varchar date to the correct Y-m-d formats using mysql's STR_TO_DATE() function eg mysql> select * from testdate; +------------+ | birthday | +------------+ | 01/15/1980 | | 10/22/1989 | | 11/09/1979 | +------------+ mysql> UPDATE testdate set birthday = str_to_date(birthday, '%m/%d/%Y'); mysql> select * from testdate; +------------+ | birthday | +------------+ | 1980-01-15 | | 1989-10-22 | | 1979-11-09 | +------------+ CAVEAT - make a copy of the table first, just in case.

It looks like you gave it a painkiller instead of curing the source of the pain. You should be checking why you are calling a function (that expects an array) with a variable that isn't an array.

According to the error message, $items is NULL. You need to find where your function is being called and investigate why the item being passed to the function has no value assigned, and put some checking code in to prevent it reoccurring.

Alternatively, assuming they all have same rigid structure, ... $fp = file('weather.html', FILE_IGNORE_NEW_LINES|FILE_SKIP_EMPTY_LINES); $data = []; foreach ($fp as $line) { switch (substr($line, 0, 4)) { case '<!--' : if ($line[4]!=' ') { $section = substr($line, 4, -8); } break; case '<td>' : list($name, $value) = getData($line); $data[$section][$name] = $value; break; default : continue 2; } } function getData($line) { $l = substr($line, 4, -5); return explode('</td><td>', $l); } // View the results echo '<pre>' . print_r($data, 1) .

The cat hasn't arrived and the others have. What's wrong with that?

Remove the break

Use varchar for columns which can have values of variable lengths (names, address lines, descriptions, comments etc) Use char when you have values of fixed length (EG US state abbreviations could be CHAR(2), or if you have a product table that has a 4-character product code then CHAR(4)). If in doubt use varchar, but don't go mad and make everything VARCHAR(255) as some do. Keep them as sensible size for the expected content. You don't want people entering a phone number with 255 digits just because your DB allows it.

An easy way to iplement a similar search is to use a datalist. For example Pupil ID : <input type='text' name='name' id='name' list='pupils'> <datalist id="pupils"> <option value="1">Adam Simms</option> <option value="2">Allan Blair</option> <option value="3">Anna Hamilton</option> <option value="4">Anne Bailey</option> <option value="5">Anthony Bell</option> <option value="6">Caroline Freeman</option> <option value="7">David Powell</option> <option value="8">Emma Watson</option> <option value="9">George Wilson</option> <option value="10">Henry Irving</option> <option value="15">Jack Williams</option> <option value="11">Jane Morrison</option> <option value="12">John Patterson</option> <option value="13">John Tully</option> <option value="14">John Watson</option> <option value="16">Margaret Norton</option> <option value="17">Mary Blake</option> <option value="18">Mary Sheldon</option> <option value="19">Mary Whitehouse</option> <option value="20">Michael Grove</option> <option value="21">Peter Adamson</option> <option value="22">Peter Appleby</option> <option value="23">Wayne Jones</option> <option value="24">William Smith</option> </datalist> The list is initially hidden by default. Entering "ma" in the input displays the names that contain "ma" When Margaret is selected, the input field then contains the ID of her record (16)

Some bedtime reading for you... https://dev.mysql.com/doc/refman/8.0/en/char.html P.S. The main difference is in the storage. Your code is demonstrating this particular feature stated in the above link Another example for you $pdo->exec("DROP TABLE IF EXISTS testchar"); $pdo->exec("CREATE TABLE testchar ( col1 char(5), col2 varchar(5))"); $pdo->exec("INSERT INTO testchar (col1, col2) VALUES ('a ', 'a '), ('ab ', 'ab '), ('abc ', 'abc '), ('abcd ', 'abcd '), ('abcde', 'abcde') "); $res = $pdo->query("SELECT col1, col2 FROM testchar"); echo '<pre>'; foreach ($res as $r) { printf (" '%s' (%d) | '%s' (%d)<br>", $r['col1'], strlen($r['col1']), $r['col2'], strlen($r['col2'])); } which outputs... 'a' (1) | 'a ' (5) 'ab' (2) | 'ab ' (5) 'abc' (3) | 'abc ' (5) 'abcd' (4) | 'abcd ' (5) 'abcde' (5) | 'abcde' (5)

If you echo $queryCondition, what do you get? And what does the value in aufdzhost look like?

If you want current date... $post_at_todate = date('Y-m-d');

Dates in formats other than yyyy-mm-dd (or similar) don't play nice when being sorted or compared with other dates. Also ensure that, when using "BETWEEN A AND B" that A is not greater than B.

try $pdo = new PDO('mysql:host=127.0.0.1;dbname=mydb; charset=utf8', 'myuser', 'mypass'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); In other words, remove your try/catch stuff - you are smothering the error reporting
