PHP - Symbol In Front Of File_get_contents..
What does it mean
Like.. !@file_get_contents('url'); or.. !file_get_contents or @file_get_contents Similar TutorialsWhat is the & symbol used for I have seen it in function setname(&$name){ $this->name =& $name; } Thanks I have looked on google and can't find it as i don't know what it is called. thanks Hello, Im getting a name from the url, for instance, index.php?name=C.-and-G The "and" is then converted to a & symbol and dashes converted to spaces. This then uses the new name "C. & G" to select a record from mysql. However, it does not recognise the & symbol, the name in mysql is "C. & G" but returns 0 records. Any ideas? Thanks! Hi, I'm looking through some code I have for setting up a rating system. It was a free open source code, which I need to change to work for my own site. I have it working, but I am now just looking through the code to try and understand it, and for the most part, I do. There is one part I am not familiar with, if somebody could help me please? Values involved; $current_rating = total rate value of votes $count = total number of votes cast Problem I have is the @ symbol here $rating=@number_format($current_rating/$count, 1); Does it format it to decimal places or something like that? It's probably something simple I know, but I am a relative newb. Thanks. I am running php 5.3.2 on my local dev and on the server I am running php 5.2.5. In my log files I keep getting deprecated messages like: PHP Deprecated: Assigning the return value of new by reference is deprecated in /Users/xxx/dev/git/xxx/cake/dispatcher.php on line 677 Can I just delete & to get rid of this message or will that hose the script locally and on the server? I believe that php 5+ passes all objects as reference. Thanks Easy One - What is the symbol for or? Example: && = and, right? What is 'or'? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=322426.0 Code: [Select] $query = "LOWER(name)="$tabB"; on my forums, speakwhatsreal.com new message page, let's say somone on my site has the name "$tabB" how do i make the above query work so it selects a username with the $ symbol in it? because with that query it's linked to Code: [Select] $DB->query("SELECT name, id, mgroup, language, email FROM ibf_members WHERE ".$query); $to_member = $DB->fetch_row(); if (empty($to_member['id'])) { $this->send_form(0, $ibforums->lang['err_no_such_member']); return; } pretty much says no results.. lol any help? I'm a little confused exactly on how using this } works going to be hard to explain what im having problems with. I'm using JEdit for my editor and I notice if I click on one of these { it will put a box around where it ends there is 4 } at the bottom of the code by them selfs "on their own lines" and 2 in the middle by them selfs "on their own lines how does the code know which ones belong to which { appreicate any help in helping me understand this thanks this code is from a tutor online Code: [Select] <? include_once("connect.php"); ?> <html> <body> <?php if(isset($_POST['Login'])) { if(!preg_match('/^[A-Za-z0-9]{5,20}$/',$_POST['Username'])){ // before we fetch anything from the database we want to see if the user name is in the correct format. echo "Invalid Username."; }else{ $query = "SELECT password,id,login_ip FROM users WHERE name='".mysql_real_escape_string($_POST['Username'])."'"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_array($result); // Search the database and get the password, id, and login ip that belongs to the name in the username field. if(empty($row['id'])){ // check if the id exist and it isn't blank. echo "Account doesn't exist."; }else{ if(md5($_POST['password']) != $row['password']){ // if the account does exist this is matching the password with the password typed in the password field. notice to read the md5 hash we need to use the md5 function. echo "Your password is incorrect."; }else{ if(empty($row['login_ip'])){ // checks to see if the login ip has an ip already $row['login_ip'] = $_SERVER['REMOTE_ADDR']; }else{ $ip_information = explode("-", $row['login_ip']); // if the ip is different from the ip that is on the database it will store it if (in_array($_SERVER['REMOTE_ADDR'], $ip_information)) { $row['login_ip'] = $row['login_ip']; }else{ $row['login_ip'] = $row['login_ip']."-".$_SERVER['REMOTE_ADDR']; } } $_SESSION['user_id'] = $row['id'];// this line of code is very important. This saves the user id in the php session so we can use it in the game to display information to the user. $result = mysql_query("UPDATE users SET userip='".mysql_real_escape_string($_SERVER['REMOTE_ADDR'])."',login_ip='".mysql_real_escape_string($row['login_ip'])."' WHERE id='".mysql_real_escape_string($_SESSION['user_id'])."'") or die(mysql_error()); // to test that the session saves well we are using the sessions id update the database with the ip information we have received. header("Location: Sample.php"); // this header redirects me to the Sample.php i made earlier } } } } ?> <form id="form1" name="form1" method="post" action=""><center> GAME LOGIN <br /> <br /> Username: <input type="text" name="Username" id="Username" /> <br /> <br /> Password: <input type="password" name="password" id="password" /> <br /> <br /> <input type="submit" name="Login" id="Login" value="Login" /> </center> </form> </body> </html> Trying to echo a string that contains a hash symbol. Instead of getting a hash symbol, I get %29. The code I am using is pretty basic -->$idx="#" . $idxA;<--, but as stated, when I echo $idx, it comes out as %29. (All of this is part of a form, get, attempting to pass a bookmark to the receiving program. Thoughts? Code: [Select] $mystring = "|Signature"; $findme = '|'; $pos = strpos($mystring, $findme); echo $pos; echo's 0 supposed to echo out 1....? why not work thanks How can I enable it to check for Code: [Select] | using strpos? This for loop: for ($m = 01; $m <= 12; $m++) Will output: 1 2 3 4 etc. And NOT: 01 02 03 04 My question is: how can I make the number be 2 digits and have it output together with the ZERO? And when it's reaching the number 10 it should continue outputting: 10 11 12 And not 010 011 etc. So I have a simple query that adds a text record into a MySQL database table. It works great with exception of one thing. I noticed that if I have "&" symbol in my paragraph, the text after that symbol won't be inserted into the table. The text before that symbol will insert fine. It seems to be doing that only with & symbol; other symbols insert and show up fine. can anyone tell me why this is happening? Hi i want to match $ symbol from the string. I am using the following script Code: [Select] $str="ckj"; if(preg_match("/^$/",$str)) { echo "Dollar is found"; } else { echo "Not Found"; } Its not working fine. Can anyone help me out please. hello i can't figure out how to modify a value from assoc array so with each recursion to add additional string to his: for example i have attribute=""; then call recursive function and i try to modify its value by concatenating "0"; or "1"; on the next loop to add again "0" or "1"; Is there a way to trim everything off in front of the last backslash in the string? Code: [Select] $trimFile = $fList[$i]; Example: In this path: \\\\myftp/downloads/tom/work/word_docs\\legal\test.pdf I only want to display test.pdf. Thanks, Jake hello , could anyone please point me on how can i read the data i input from an html page to appear on the mysql front server. ive print screen my problem this is the signup page ,where i input the user name and password here's the signup page html code """<html> <head> </head> <body> <h1>Personal Info</h1> <form name="form" method="post" action="SignUp.php"> <p>UserName:<input type="text" name="usrn" /></p> <p>Password:<input type="password" name="pass" /></p> <p><input type="submit" value="Sign Up"/> <input type="submit" value="Clear" /></p> </form> </body> </html> """"" and this is the mysqlserver ,where i want the username and password i entered to show here's the php code i wrote """"<?php $usr=$_POST["usrn"]; $pass=$_POST["pass"]; $db=mysql_connect("localhost","root",""); mysql_select_db("realestate",$db); $q="insert into Customer Values('$usr','$pass')"; mysql_query($q); mysql_close(); ?>""""" i would really appreciate any help from you guys.
