PHP - How Do You Echo/flush Strings During Script Execution?
I have looked at ob_start, ob_get_contents, etc.. but I can't get it to work. My code looks like this:
Code: [Select] ob_start(); echo "starting"; ob_flush(); //do some stuff echo "something else" ob_flush(); //do some stuff echo "something else" ob_flush(); The echoes are only shown at the end of the script execution. Similar TutorialsI have a series of string which can have a value or empty. I want to display them with echo. echo $string1 $string2 $string3; satisfies my need, as it shows available values, but with this method, I will get a PHP notice in my error_logs. What is your suggestion? Do I need to use "if (empty)" or "if(isset)"? The point is I have numerous strings and in each run only few of them have value. Code: [Select] <?php //Start session session_start(); //Include database connection details require_once('config.php'); //Array to store validation errors $errmsg_arr = array(); //Validation error flag $errflag = false; //Connect to mysql server $link = mysql_connect($hostname, $username, $password); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } //Select database $db = mysql_select_db($dbname); if(!$db) { die("Unable to select database"); } //Function to sanitize values received from the form. Prevents SQL injection function clean($str) { $str = @trim($str); if(get_magic_quotes_gpc()) { $str = stripslashes($str); } return mysql_real_escape_string($str); } //Sanitize the POST values $login = clean($_POST['login']); $password = clean($_POST['password']); //Input Validations if($login == '') { $errmsg_arr[] = 'Login ID missing'; $errflag = true; } if($password == '') { $errmsg_arr[] = 'Password missing'; $errflag = true; } //If there are input validations, redirect back to the login form if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0 ) { echo '<ul class="err">'; foreach($_SESSION['ERRMSG_ARR'] as $msg) { echo '<li>',$msg,'</li>'; } echo '</ul>'; unset($_SESSION['ERRMSG_ARR']); } session_write_close(); header("location: index.php"); exit(); } //Create query $qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'"; $result=mysql_query($qry); //Check whether the query was successful or not if($result) { if(mysql_num_rows($result) == 1) { //Login Successful session_regenerate_id(); $member = mysql_fetch_field($result); $_SESSION['SESS_MEMBER_ID'] = $member['member_id']; $_SESSION['SESS_FIRST_NAME'] = $member['firstname']; $_SESSION['SESS_LAST_NAME'] = $member['lastname']; session_write_close(); header("location: member-index.php"); exit(); }else { //Login failed header("location: login-failed.php"); exit(); } }else { die("Query failed"); } ?> This is my login execution script and when i run it, i get this - Fatal error: Cannot use object of type stdClass as array in /home/a8029060/public_html/login-exec.php on line 75 Please any help :/ Hello all, newbie here just trying to understand PHP and other languages. As a basic, i understood that exit() function is used to stop something. But, was wondering if below code is right to terminate something. Ref - InterviewBit
<?php
$site = "https://abcdefghijk.com//";
fopen($site,"r")
or exit("Unable to connect to $site");
?>
TIA!! Hi All,
I'm hoping somebody would be able to help me with a performance issue I'm having with a bit of code I've written.
The setup:
Client request arrives on Apache2 reverse proxy over HTTPS. SSL is offloaded and proxy initiates connection to backend development web server over standard HTTP. The website is being developed using HTML5 syled with CSS, Javascript (to dynamically show counters on message text area, perform client side validation for browsers that do not support the build in HTML5 input validation) and PHP for server side validation and form submission (sends email to webadmin).
The development web server is located in a LXC container on the production web server. The host server presents the "public" IP address to the physical network and uses UFW to NAT all traffic inbound and outbound from the development website to trick the network into thinking that the server is on the physical network (Only way to get it routeable across the rest of the network).
The problem:
On form submission, if I intentionally leave the fields blank and turn off client side validation, the script echos "An error occured in your form, please check to make sure that all relevent fields are filled in!!!". This response returns in 16.50ms with a latency of 34.92ms. The POST appears instantly in the Apache2 logs less than a second after I submit the form.
If I submit the form with all fields (Name, Email, Phone, Website, Subject and Message), it takes 60 - 65 seconds before Apache logs the POST has arrived. I'm not entirely sure why its taking this long for the server to receive the content. GET Requests are pretty much instant as I would expect. Could this be an issue with inefficient scripting that maye be causing this type of delay? This issue occurs regardless of whether I use firefox or Safari.
Could this be a result of inefficient scripting? Using timelines in Safari and on form submission with content, I get 1.0min latency with an actual duration/script run time of 5.336ms. Where would this latency be coming from? Standard GET requests for HTML and CSS content is instant, next to no latency but once the Payload increases in size, it seems like I run into the issue.
Any views, thoughts or possible things to try would be hugely appreciated. I'm learning the ropes with scriping at the moment but this high latency, as a hunch, appears to be server related. Happy to upload the submit.php script and web form if it will help.
Many Thanks,
A
hello, I am using a script which takes backup of my database and convert it into a zip file, I am getting following error Code: [Select] Fatal error: Maximum execution time of 30 seconds exceeded in /home/USERNAME/public_html/functions.php on line 110 I know I read and search forum for solving this by editing PHP.INI file, but i Have no access to it So is their any way that I can able to run the script but modifying it??

The doctor's referral requests are sent to a mySQL database and I have, with the help of online guidance, produced a working php script that displays the information I need it to. However, I need it a little bit more specific. I intend to make multiple copies of this file for each specialty, so that when they open the file they only have the requests for that particular specialty. My question is, with reference to my code below, can I make echo information so that online, for instance, if 'specialty1 = gastroenterology' (as in, that particular specialty that that referral request is for), then only the rows on the database that have that particular text are displayed only? Hope that makes sense. Code below for your reference and assistance is highly appreciated.

I guess what I am looking for is something like echo specialty1 IF it writes a particular specialty and only that specialty. Thank you. Edited April 2, 2020 by samanjGood Afternoon Team, Am sitting with something simple using the language below. If I copy the echo output of my query as included below it works perfectly in phpmyadmin but doesn't work on a website. Variables all seem to echo consistently/correctly and POST checks seem to verify this is working correctly as well. I worry the error comes with the syntax I used in combining the sql queries. That, or perhaps LAST_INSERT_ID does not work in the php script as well as it does in phpmyadmin. All help appreciated.

Hi, I am pretty much a new newbie when it comes to PHP, and have a problem that I need to solve, for a website that has to go live tomorrow. Basically I have been using a javascript upload script called 'uploadify' which had an option for the upload folder which was added to the script in the form: Code: [Select] 'folder' : '/songs/<?php echo $_SESSION["name"];?>', I added the php echo to return the username from a PHP login, so it gets added to the path to the upload folder (each user has their own subfolder for uploading to). With the new version of the uploadify script, the folder option has been moved to a separate PHP file where it is now in the form: Code: [Select] $targetFolder = '/songs/'; I need to find a way of adding the username variable to this line. I have tried using echo in various ways, and googled about, but it has stumped me, simple as it may be. If anyone could let me know how I construct this line I'd be very grateful. Time is of the essence, as they say... Thanks, Nick Hey guys! I found a flush function and it seems to be working well, but sometimes it will cut off characters. It's very strange. Here's my flush function: function out($str) { echo $str."<br />\n"; vbflush(); } function vbflush() { if (ob_get_length()){ @ob_flush(); @flush(); @ob_end_flush(); } @ob_start(); }And I'm calling it like this:out('Waiting 30 seconds until execution');And this is my output: Code: [Select] Waiting 30 seconds until executioAnyone know why? What is the PROPER way to clear out an array? I have an array getting created as part of a loop process, and for each loop, I want the array to be emptied and start from scratch? I googled it and see some ways but the people offering the solutions don't seem too sure of themselves, so I just want to know if there is one, widely accepted and proper/efficient way to do this? OK, have no idea what's going on... I've done this a million times... why wont this output!?? I must have a major brain meltdown and dont know it yet!!! Code: [Select] <?php // this echoes just fine: echo $_POST['testfield']; // but this wont echo: echo if (isset($_POST['testfield'])) { $_POST['testfield'] = $test; } echo $test; /// or even this DOESNT echo either!: $_POST['testfield'] = $test; echo $test; ?> Is there a way in php to not execute the whole script if there is error on the script? For example: Code: [Select] <?php execute script here; .......... ........... [b] error encounter here[/b]. -> error is not logical execute script ............. ............. ?> I don't want to execute the above script... tnx everyone. Hello, I am developing an account manager for our local network and I want people to be able to login to my website and change their UNIX & Mailbox password. These people have SSH access so that is why the UNIX passwd should also be changed. So what I want to do is get the values $username, $currentpwd , $newpwd and $newpwdcnfrm from the HTML form and execute the following shell commands : Quote su -l $username passwd Enter current UNIX Passwd : $currentpwd Enter new UNIX Passwd : $newpwd Confirm UNIX Passwd : $newpwdcnfrm The problem here is, passwd takes old and new passwords as input, not as command parameters. So I cant just do shell_exec("passwd $currentpwd $newpwd $newpwdcnfrm") ; Do you guys know how to give input to the command? thanks. Btw : Please do not argue about the security issues. I am aware of everything and I am perfectly sure that the script will run securely. hey guys... below is my code... when i hit the "submit" button the browser displays the php file rather than writing to the db... can anyone see what im doing wrong .. thanks Code: [Select] <table width="300" border="0" align="center" cellpadding="0" cellspacing="1"> <tr> <td><form name="form1" method="post" action="insert_ac.php"> <table width="100%" border="0" cellspacing="1" cellpadding="3"> <tr> <td colspan="3"><strong>Insert Data Into mySQL Database </strong></td> </tr> <tr> <td width="71">Name</td> <td width="6">:</td> <td width="301"><input name="name" type="text" id="name"></td> </tr> <tr> <td>Lastname</td> <td>:</td> <td><input name="lastname" type="text" id="lastname"></td> </tr> <tr> <td>Email</td> <td>:</td> <td><input name="email" type="text" id="email"></td> </tr> <tr> <td colspan="3" align="center"><input type="submit" name="Submit" value="Submit"></td> </tr> </table> </form> </td> </tr> </table> Code: [Select] <?php $host="localhost"; // Host name $username=""; // Mysql username $password=""; // Mysql password $db_name="test"; // Database name $tbl_name="test_mysql"; // Table name // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Get values from form $name=$_POST['name']; $lastname=$_POST['lastname']; $email=$_POST['email']; // Insert data into mysql $sql="INSERT INTO $tbl_name(name, lastname, email)VALUES('$name', '$lastname', '$email')"; $result=mysql_query($sql); // if successfully insert data into database, displays message "Successful". if($result){ echo "Successful"; echo "<BR>"; echo "<a href='insert.php'>Back to main page</a>"; } else { echo "ERROR"; } // close connection mysql_close(); ?> Hi,
