can anyone help me please. In a loop, I get a list with page titles from an external website. And these titles are unknown strings. Every Page title has a name and a ID like "NAME X - PRJ12345".
the title are saved in $title_mainpage
And I want to save the String Part "NAME X" in variable $title_name and the unknown ID of the String in variable $title_id.
Every title are different, but the ID has always the same length - start with "PRJ" + 5 numbers.
I hope the question is clear. Thanks in advance!!
$x='NAME X - PRJ12345';
$arr=explode('-',$x);
$title_name=echo $arr[0];
$title_id=echo $arr[1];
You can do this by using list and explode functions. list actually assign variables to the values as they were in arrays. While explode break the string into array. With the help of list you don't need to use arrays explicitly.
$variable = "NAME X-PRJ12345";
list($title_name, $title_id) = explode('-', $variable);
echo $title_name . "<br>";
echo $title_id;
Possible output will be like this:
NAME X
PRJ12345
For deep information you can see documentation for list and explode

i need to assign room number string value into $rooms_db variable and explode it using , and assign the seperated values in to $rooms_arr. but there is a error says that:::: Expected type 'string'. Found 'array'.intelephense(1006) enter image description here
code is :
$rooms_db = DB::SELECT("SELECT room_number FROM bookings WHERE '$checkin_date' BETWEEN checkin_date AND checkout_date ");
$room_arr =explode(",",$rooms_db);
return response()->json(['data'=>$room_arr]);
i am very new to programming. can you solve this problem . thank you
You query result ($rooms_db) is type of array of object, not a string.
So no need to explode.
Please use this stuff instead of explode
$room_arr = array_map(function($item) { return $item->room_number; }, $room_db);
I am looking for a possibility to pass db table name and column name via php and GET parameter.
I have a data grid with following structure:
table_name1.column1, table_name2.column1, table_name2.column1.
There is a search function for the grid, where I need those parameters.
From the url "?table_name1.column1=22" I am getting through the $_GET only table_name1_column1=22
How would you solve that?
Encode the variable with base64 and decode before you use.
I know that's dirty.
But php variables doesn't support periods (dots)
This is a documented feature of PHP. Its basically because PHP cannot have variable names with dots in them.
$x.y = 1 // is an invalid variable name
MANUAL Convert dots to _ in GET & POST
You can use serialize function of php to pass the text "table_name1.column1" in url. But for that you need to do few coding to get the result. Below I have given code which you can use:
Page1.php
<?php
$test = serialize('table_name1.column1=11::table_name2.column2=22');
?>
<a href='Page2.php?qs=<?php echo $test?>'>test</a>
Use this $test to pass as query string. In above example, I am passing on anchor tag click.
Page2.php
use following code to Unserialize the query string and use the values.
<?php
$test2 = unserialize($_GET['qs']);
$ex = explode('::',$test2);
$new_arr = array();
foreach($ex as $val)
{
$ex2 = explode('=',$val);
$new_arr[$ex2[0]] = $ex2[1];
}
echo $new_arr['table_name1.column1']; //print 11
echo $new_arr['table_name2.column2']; //print 22
?>
Hope this will help you :)
You need to seperate each parameter with &.
So: ?table=table_name1&column=column1
I have two strings in PHP:
$Str1 = "/welcome/files/birthday.php?business_id=0";
$Str2 = "/welcome/index.php?page=birthday";
I have to get word birthday from this two string with a single function.
I need a function which returns birthday on both case.
example
function getBaseWord($word){
...
return $base_word;
}
getBaseWord('/welcome/files/birthday.php?business_id=0');
getBaseWord('/welcome/index.php?page=birthday');
both function call should return "birthday".
How can i do it.
If I correctly understand what you are trying to do then this should do what you need:
function getWord(){
return $_GET['page'];
}
or $_GET['business_id'];
I think $_GET is an associative array made from the GET request that was sent to the page. An associative array is one where you access something like ['name of the element'] instead of [1] or [2] or whatever.
So what you will need to do is get all of the actual GET variables extracted from the string:
//Seperate the URL and the GET Data
list($url,$querystring) = explode('?', $string, 2);
//Seperate the Variable name from its value
list($GETName, $GETValue) = explode("=", $querystring);
//Check to see if we have the right variable name
if($GETName == "page"){
//Return the value of that variable.
return $GETValue;
}
NOTE
This is very BASIC and will not accept more then one GET parameter. You will need to modify it if you plan on have more variables.
I have no idea what you are talking about but, you can cut the word "birthday" with str_replace and replace with another word, or you can find the position with stripos, I have no idea what we are trying to do here, so those are the only things come to my mind
I have a "recruiter" table in my database which has different attributes and one of them is "Professions". "Professions" is a serialized array which I get from a multiple select form. And this works fine.
When I unserialize this attribute nothing is printed - no error, no text.
This is a code I was testing serialization with:
$sql = 'SELECT Company_name, Status, Size, Professions, Seniority_levels, Sector, Website, Location FROM Recruiter';
$query = mysql_query($sql, $con);
while($result = mysql_fetch_array($query, MYSQL_BOTH)){
$recruiters[] = array($result[0], $result[1], $result[2], $result[3], $result[4], $result[5], $result[6], $result[7]);
}
foreach($recruiters AS $recruiter){
$test = unserialize($recruiter[3]);
echo $test[0].'<br>';
}
So basically $test[0] prints nothing although the new lines are printed. Please help!
try printing the $test array and the $recruiters and the $recruiter arrays. See if the result is fine before the unserialisation of the data. If the query returns any data. Also try the while loop with mysql_fetch_assoc. Let me know of the results and if this solves the problem
test = unserialize($recruiter[3]); should become test = unserialize($recruiter[5]); since the sector field is the sixth column .
However what if somewhere in the future you might need to select rows where sectors equal smth ? serialize whont help you then so i suggest you have a look at a different implementation for the sector filed witch is called bitwize http://www.litfuel.net/tutorials/bitwise.htm
Edit
Asuming you hit the right column and the column contains a:1:{i:0;s:27: a:1:{i:0;s:27: a:38:{i:0;s:27: a:9:{i:0;s:39:, it looks like the serialized array is not fully saved in you're db, it's only part of it . So the unserialize function whont return you an array . Have a look at the length of the mysql field i assume you've set it smaller than you need so you're data is trimmed on insert/update .
Edit
a:1:{i:0;s:27: you're still missing the rest of the serialized array . s:27: means a string is following containint 27 characters, and you're serialized array stops there when it should look like
a:1:{i:0;s:27:"123456789012345678901234567";}
( a:1 stands for an array containing 1 value with it's content between {}, i:0; is the array key 0, s:27:""; stands for a string containing 27 characters as the value for the i:0 key ) .
This is a two part question. First how can I grab the last url value from a link when I dont know how deep the value is, for example how can I grab
the last value of sub_4 from the link example below using PHP? And second how can I grab the url value cat=3 and the last url value sub_4 using PHP?
I'm kind of new to PHP so a detailed step by step example would help me out a lot if its not too much trouble.
Thanks in advance!
Here is an example of a URL value.
http://www.example.com/categories/index.php?cat=3&sub_1=sub1&sub_2=sub2&sub_3=sub3&sub_4=sub4
All variables from the hook will be returned on $_GET. So if you want to get that value from the URL, just use:
$_GET['sub_4']
If you want to get a list of all of the possible values:
array_keys($_GET)
This will give you all of the variables.
UPDATE: I just reread your question. I think I better understand what you are looking for. Correct me if I am wrong, but you are not certain how to get the last element of the string? Is that right? So you could potentially have sub_5, sub_6, sub_7 etc. Here is how to get the last element from the string:
end($_GET);
$key = key($_GET);
$last_item = $_GET[$key];
$last_item will now have sub_4 (or what ever the last item is).
Extracting URL Parameters
Query parameters (anything in the URL with ?name or &name) are saved in the $_GET superglobal.
If sub is a hierarchy, you should probably just write it as such. For instance: ?sub=path/to/sub or ?sub=path:to:sub
From this you can explode() on your separator (/ or :) to get the different parts of the sub parameter. $sub_array = explode('/', $_GET['sub']);
You can then iterate over the array using a foreach or directly access the highest branch of the hierarchy using count():
$sub_array[count($sub_array-1)];
Building URL Parameters
If you have an array of subs that you want to use to generate a URL, you can use implode() to build your URL params. $sub_params = implode('/', $_GET['sub']);
You might construct that array by appending each sub to the $sub_array.
$sub_array[] = 'sub1';
$sub_array[] = 'sub2';
$sub_array[] = 'sub3';
etc.
Inspect the Data
If you get lost, use var_dump($_GET) or var_dump($variable) to see what's inside it.
Each cat=3 or sub_1 value can be retreived by $_GET['cat'] and $_GET['sub_1'] respectively. To elaborate, $_GET['NAME_OF_PROPERTY'] would look like php.net/index.php?NAME_OF_PROPERTY=whatever
It seems like both questions were on how to grab the value from the URL, so I hope that answers both.
In your example url http://www.example.com/categories/index.php?cat=3&sub_1=sub1&sub_2=sub2&sub_3=sub3&sub_4=sub4
echo $_GET['cat']; // 3
echo $_GET['sub_1']; // sub1
echo $_GET['sub_2']; // sub2
echo $_GET['sub_3']; // sub3
echo $_GET['sub_4']; // sub4
For the first part; you should use the $_GET[] array which contain every parameter passed in the url $_GET['cat'], $_GET['sub_1'].
For the second part, in your case you should try send an array in parameter like this :
http://www.example.com/categories/index.php?cat=3&sub[1]=sub1&sub[2]=sub2&sub[3]=sub3&sub[4]=sub4
And then use the $_GET['sub'][] array $_GET['sub'][1], $_GET['sub'][2], ...
Now you can determine the length of the array and know the last item in it.
This example is under the assumption you want to find the very first variable in the GET query, and the very last:
<?php
// Here, you separate all the variables
$parameters = explode("&", $_SERVER['QUERY_STRING']);
// Get the last key's index
$last_key_index = count($parameters)-1;
// Easy way for PHP 5.3
$first_key = strstr($parameters[0], "=", true);
$last_key = strstr($parameters[$last_key_index], "=", true);
// Bit longer otherwise
$first_key = substr($parameters[0], 0, strpos($parameters[0], "="));
$last_key = substr($parameters[$last_key_index], 0, strpos($parameters[$last_key_index], "="));
// Test it here
echo($first_key);
echo($last_key);
?>
