PHP - Arrange Sections Of An Array?
I have an array, and to make it easy let's say they have 2 values: ET and SPEED
Here is an example chart of the array printed out: KEY ET SPEED 8 5.2 60 3 5.3 60 1 5.4 70 7 5.4 60 9 5.4 90 6 5.5 60 5 5.6 60 2 5.6 65 4 5.7 60 I need to take this array and each group that has a matching ET, put them in order based on SPEED. The corrected chart should be like this: KEY ET SPEED 8 5.2 60 3 5.3 60 9 5.4 90 1 5.4 70 7 5.4 60 6 5.5 60 2 5.6 65 5 5.6 60 4 5.7 60 Just not sure of how to only arrange the section that need to be. Keys stay the same, just the order changes. Similar TutorialsHi all, I am trying to fix some easy script that explodes a string into an array. Which goes fine. The only problem i have is that if i echo out the Key of the array it starts of course by default with 0 Does anyone know a quick may to rename the keys and start with 1 instead of 0. so to make it more clear: Value: Key: | | Value: Key: ------------------------------------------------------------------------------------------- johny 0 | | johny 1 willy 1 | should look like => | Willy 2 monkey 2 | | monkey 3 adrian 3 | | adrian 4 ------------------------------------------------------------------------------------------- This a small part of what i have which works but of course starts with index 0 <?php $string = array('johny','willy','monkey','adrian'); print_r($string); ?> Just a small side note: This is a string that catches input from a text-area and explodes it based on a newline character. But for the sake of simplicity i provided a ready made array. But I was wondering if someone knows a nice and clean way to re-arrange the key of the array (which the user has no influence on). I was thinking of a loop and increment the array key, but that might be redundant. Any hints or help are appreceated Hello everyone !
I am currently developing a module for my site that will allow me to classify each solution to help a disability by type. Type : Visual disability Solution : Add screen readers For this, I have a database in which these types and solutions are found. In this database, the solutions of one type or another are not in a defined order. They can be put randomly, when a user adds one. I need to display, in a table, these Types first (as a title), then the solutions corresponding to this type. I manage to generate a display thanks to a foreach loop, but my solutions are all mixed up and therefore not clearly sorted.
Visual disability Audio-described cut-scenes Highlighted path to follow Sensitivity settings for all the controls Screen readers on menus Slow down the game speed But I would need it to look like this: Visual disability Audio-described cut-scenes Highlighted path to follow Screen readers on menus Slow down the game speed Physical disability Sensitivity settings for all the controls In my example above, only the solution "Sensitivity settings for all the controls" is part of the "Physical disability" type. The rest is part of the "Visual disability" type. Here is the code I currently use to retrieve my information from my database and display it. It's a Wordpress.

Edited January 13 by Sagaroth how to arrange a port forward via ssh-tunnel i need to do that on a domain with this syntax https://www2.mydomain.org:2211/ i am on opensuse guess that i firstly have to activate the ssh so i have this string that i want to search on the database My database has 3 parts city, state, country and i have a string that is say "new york city, ny, united states" and i want to be able to be able to look into the database but search those three sections so for example "New York City" i would like to search under city "NY" i want it to search under state and "United States" i want to search under country so basically how can i split the string into those three sections?? hope someone can help me with this This should be an easy one but I'm looking for a bit of help. I'm using a php framework and using includes to bring different pieces of a website togethor onto the page. The top of the page uses a flash banner, then there are some simple text sections below. The banner is in it's own php file as well. Wondering if it's possible to have the banner NOT replay after each page load? I'm not sure if this is something I need to setup in the flash file, or if there is a way to do it in the php files? Basically, the banner is the same for all of the pages, and I want it (once loaded) to stay on the page while the details on the bottom change, WITHOUT going through the entire animation again. Make sense? here's the page as it stands now so you can get a better idea what I'm trying to do. http://www.getmoreimpact.com/index.php again not sure if this needs to be done in the flash side, or the php? Any ideas are better than what I've got! Thanks in advance I need help arranging a text blob into a table of where each cell is a letter, and the contents of the text blob must be arranged in the table according to what letter it starts with.

Thanks in advance! Ryan Hi, I am working on a project, where i want to add sub-sections within a section , and add once again adding sub-subsection under that section. How to make a table structure for that, any idea please Thanks, The snippet repository section has been read only and nothing new for a long time.
Most of the ones there are pretty old.
The tutorials sections last post was from 2010
The old pagination tutorial needs a good mysqli and pdo version there.

I noticed how slow the sites been a while now, maybe need something to lure more in.
I embed videos on my site. I submit the embed codes to my database using a form. The codes look like this:
<iframe width="560" height="315" src="//www.youtube.com/embed/xDIgbjDGsOM?rel=0" frameborder="0" allowfullscreen></iframe>Before I submit each code, I have to change its width and height, and I have to add this: &showinfo=0after this: ?rel=0Is there a function that will allow me to do all of that simultaneously? I know about str_ireplace(). It will let me replace ?rel=0 with ?rel=0&showinfo=0, but I don't know how to simultaneously make the other changes. It's not helping that the embed code includes quotation marks. I would like to grab sections out of a body of text, but I am not sure how to get started with this... So, lets say I have an array of word to find in the doc $words = array_unique(array('the', 'squirrel', 'jumped', 'the', 'fence')); Using that array, I would like to get key section in the body of text (that was passed to the function) and get about 25 characters before the text and about 25 after. I want a maximum of three sections, and have them concatenated by some dots. basically it is the same look as google: Quote Once located, block off all but one using flashing, wire fence or hardware cloth. .... If the squirrel is jumping from high to low, as from a tree Any Ideas how I could do something like this?

Thanks.. I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? I have mysql select query shown below retrieving data from a database:
$sql = " SELECT student, sum( test_score ) as score FROM test INNER JOIN level ON test.level_id = level.level_id GROUP BY student" $result = $mysqli->query($sql, MYSQLI_STORE_RESULT); if($result) { while ($row = $result->fetch_array(MYSQLI_ASSOC)) { var_dump($row); } }On inspection of the retrieved array with var_dump(), i have these result below: array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. |
