PHP - New To Php - Question About Semicolon
Hi, I'm a beginner just learning PHP right now, so my question is probably a simple one but I can't seem to figure this out.
I'm trying to code the following if/else statement. When I've tested the code, the echo "Value is not a number" is appearing as if it were not part of the if/else statement. Is it not working because of the semicolon at the end of the first echo statement? Or am I missing another set of curly braces? I'm not sure how to approach this . . . <?php for ($row=1; $row<5; $row++) { $value_of_amount = $_POST['value_of_amount']; if (is_numeric($value_of_amount)) { echo "<tr><td> $value_of_amount </td>"; } else { echo "<tr><td> Value is not a number </td>"; } } ?> Similar TutorialsI'm having an issue with users uploading files with a Semi Colon in the file name. I am currently using a script that replaces characters within the file name, however, when I try to add a ";" as invalid characters to replace, it is like the semi-colon just stops the script, as the file does not upload (no errors are displayed). Here's the code I'm working with: $valid_chars_regex = '.A-Z0-9_ !@#$%^&()+={}\[\],~`-'; $file_name = preg_replace('/[^'.$valid_chars_regex.']|\'.+$/i', "", basename($_FILES[$upload_name]['name'])); if (strlen($file_name) == 0 || strlen($file_name) > $MAX_FILENAME_LENGTH) { HandleError("Invalid file name"); exit(0); } I tried placing the semi colon all over the place in the preg_replace function, but nothing seems to work. How can I do this? I'm getting this error: PHP Parse error: syntax error, unexpected ';' in [...] on line 44 This is line 44: $file_string .= ($article_id == count($xml->channel->item) ? '<a>></a>' : '<a href="#' . $article_id-1 . '">></a>'; EDIT: Nevermind, I found it! The parenthesis at the end, duh. The following code returns thousands of results separated by a semicolon; Code: [Select] while($getpostid_result=mysql_fetch_array($getpostid)) { $postusername=$getpostid_result['username']; echo $postusername.";"; } the problem is it does not print everything in one row.it breaks into the nextline after if it encounters certain chatacters or some other reason. I want it to able to print everything in one row irrespective of the number of results returned. when in a form, I wish to build a conditional that if the response to a radio button is a value of 2 (female), it will display an input requesting for users maiden name. If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. say i have a mysql table with the following fileds user_id picture_category picture_title picture_description picture_thumb //small image size picture_normal //large image size. ok what I'm trying to do is this. if( user_id && picture_category == the same name show all the pictures in that category as one section) //show this category and all the images from this user_id and picture_category so if this user_id has a new category name and new images uploaded it would show the images in the right category. my php xml script is in the works and is looking like this so far. <?php include "../../connect.php"; Header('Cache-Control: no-cache'); Header('Pragma: no-cache'); $username = mysql_real_escape_string($_GET['username']); $user_folder = mysql_real_escape_string($_GET['user_folder']); //$password = mysql_real_escape_string($_GET['password']); $friend = (isset($_GET['friend'])) ?

I also have a join table included to join if this user has friendship with that user. and then you would see all your pictures upload and category's. and all your friends pictures and category's. hi php people, I am wondering will if the code below will work when I call $C->getafoo() will I get foo; I keep getting an error at this point return $this->A->a(); saying the method is not there Code: [Select] class A{ public function a(){ return "foo"; } } class B { public $A; function __construct($A) { $this->A = $A; } public function geta(){ return $this->A->a(); } } class C extends B{ public function getafoo(){ return geta(); } } $C = new C(new A()); echo $C->getafoo(); I am trying to make my database search only search where private = '$priiv'(Usually 0,1, or 2) but it does not work Code: [Select] $query_search = "SELECT * FROM users WHERE username LIKE '%$idea%' OR fname LIKE '%$idea%' OR lname LIKE '%$idea%' OR tags LIKE '%$idea%' AND private = '$priiv'"; What am i doing wrong? Major breakthrough. utf8_encode() allows me to view utf-8 characters in the browser. Therefore, my source data file must be ISO-8859-1 encoded text, right? Am I understanding this correctly?
<?php
//mb_internal_encoding("UTF-8");
header('Content-type: text/html; charset=utf-8');
$file = fopen('some_csv_file_created_by_excel.csv', "r");
ob_start();
while (($spec = fgetcsv($file, 100000, ",")) !== FALSE){
echo($spec[0].' '.utf8_encode($spec[0]).'<br>');
}
$string=ob_get_clean();
?>

Edited by NotionCommotion, 11 January 2015 - 08:22 PM. I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far Code: [Select] <?php class Horse { public $strength; public $speed; public $agility; public function create($name,$age,$odds){ $this->name=$name; $this->odds=$odds; $this->strength=(rand(50,200) * $this->odds - $this->age); $this->speed=(rand(100,400) * $this->odds - $this->age); $this->agility=(rand(150,250) * $this->odds - $this->age); $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility"); echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>"; } } $mix=rand(2,6); $a=new Horse; $a->create("Dave", 2, $mix); $a->create("Dude", 3, $mix); $a->create("Evan", 3, $mix); $a->create("Jill", 15, $mix); $a->create("Flex", 10, $mix); ?> I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong. i have took a test that i think it has some errors: can you please confirm or infirm that A is the right answer? Question: The default value for __FILE__ is _______________________________. A. the complete path of the currently executing script B. the relative path of the currently executing script C. a magical constant; it does not have a default value D. the complete path of the previous executed script E. the relative path of the previous executed script Correct Answer: C User Answer: A Explanation: The PHP engine stores the full path and filename of the currently executing script within the __FILE__ constant. Just get started with OO in PHP. If I create an object while on one page and then call another page, can I still access that first object, or is it destroyed when the second page is called? For example, if I have on page1.php: Code: [Select] $obj = new $MyObject(); and then call page2.php, is it possible to still access $obj while on that page? hi, im trying to say if field ARTIST = Eminem then do the following. here is my current code Code: [Select] $hmm = simplexml_load_file('http://localhost/1.0/?method=player.getPlayQueue'); foreach($hmm->tracks->track as $tracks) { $artist = $tracks->artist; $title = $tracks->title; $album = $tracks->album; $index = $tracks->index; $id = $tracks->id; //If we submitted the form if('.$artist.'="eminem") { echo '<table border="0" width="70%" align="center">'; echo '<tr>'; i just need to know how to do the if(***) part. thanks. Hi, I am looking into a way of adding addons to a class I made.. I thought something like this would work, but not sure how to implement it: Code: [Select] <?php class foo { function foobar($text) { $text = $text . 'b'; return $text; } } class bar extends foo { function foobar($text) { $text = $text . 'c'; return $text; } } $var = new bar(); $var->foobar('a'); // this would then return abc ?> Now i want to be able to call up foo, and it calls the foobar of foo, and the foobar of bar. is that possible? hosh Im not new to php but I am trying to think if this possible. I want to write a php script that creates a div inside a div until lets say 10 divs are created. I have been trying do while statements but them seem to place them underneth each other not within. I want <div id=one"> <div id=two"> <div id=three"> </div> </div> </div> Only thing I can create is <div id=one"></div> <div id=two"></div> <div id=three"></div> Like I said I dont even know if this is possible or if I am just retarded and can't think of a way to do it but it would be nice to see what others have to say about it. Looking at a forum like PHPbb or similar. Wondering if anyone can tell me how the system (or scripts) manages to pull all the user information when viewing a thread without a massive amount of database calls? For example, lets say 1 thread has 10 different users associated to it. When you view the thread, on the left you see the username, their avatar, when the membership was created, maybe even the users level or amount of interaction. So, for each thread view (or page view) does the program do a SQL Select back to the user database for each user's information or is the users information being pulled from cache somewhere? Any insight into the logistics is greatly appreciated! I have been away from PHP for a long time and I was looking over my old scripts. I did PHP OOP at one time and I used a paticular method to connect all my methods up and load them. I have been looking at other peoples code and when I look at my code it does not even feel like OOP, I want to know how to you link all the methods (or is it called functions?) in a class up and return them? I use to do this: Code: [Select] <?php class quickFUNC { function note_pad() { // code for notepad } function quickAdminFunc() { // code for admin func $this->note_pad(); } } $quickFUNC = new quickFUNC; if(isset($_GET['id'])) { $act = $_GET['id']; } else { $act = NULL; } switch ($act) { case 1: //some random code to launch case 1 break; default: $quickFUNC ->quickAdminFunc(); ?> This was my code back in the days, as you can see the notepad was called in the admin function then made the admin function default in the case switch. I looked at all my script and the all are layed out like this :S.. Can I get some help please, thank you. Hello. I'm trying to pull information out of an xml file. However I'm a bit lost in getting the actual value. Code: [Select] $url="http://ws.audioscrobbler.com/2.0/?method=artist.getimages&artist=Dr%20Feelgood&limit=1&autocorrect=1&api_key=c107c9b5c09cb5693b6c19409dd984c1"; $xml = simpleXML_load_file($url,"SimpleXMLElement",LIBXML_NOCDATA); $largesquare=$xml->images->sizes->size[2]; Is what I have but its not pulling the information. The above url will give you the link to a set xml file for this example. And I want to get the info for the Code: [Select] <size name="largesquare" width="126" height="126">http://userserve-ak.last.fm/serve/126s/43173899.jpg</size> I'm sure I'm doing something wrong that's a simple fix but I am lost here. In the sizes there are 6 different size options each with different names and I have no idea how to pull the one with the correct name that I need. Thank you to who ever can help me sort this out. Hello, I have a 'strange' situtation. I have this string "Who Am I" that will be used as an header (site for a client) but the design shows that the word "Who" and the words "Am I" are in 2 different colors, in HTML this is a quick fix, but in PHP? What I was thinking was explode the string and fetch the first element put it in a var en then concat the 2 others. But what if the title is more then 3 elements after exploding? It needs to be more dynamic, but I don't know how to do it. Does anyone have an idea? I'm considering getting a VPS, but I'm not entirely sure what this would be able the handle. The specs doesn't look that good to me, but my friend swears it will handle running apache/php/mysql handling large websites and databases without a problem. I want to run multiple databases that just store statistics and I'm a bit worried about the RAM and the company doesn't even mention a cpu. Here's the specs: 256MB RAM 300GB HDD 10Mbps unmetered 1 IP Address My friend runs two counter-strike: source servers off his VPS (same stats).. so I'm actually considering this, but it just seems like it's not powerful enough. Oh.. forgot the most important part.. it's only $9. In php, which function is best used to act something like the sql "LIKE" command? and how would that function be used like? |
