PHP - Shell_exec Do Not List Whole Output
In the browser when I open the file I need to see the output of the ifconfig linux command on the server.
This is the index.php <? $iplist = shell_exec("ifconfig"); print "<pre>$iplist</pre>"; ?> but when I open the index.php in a browser I can see only the first couple of lines, nothing more. Can someone help me what to do? The strange thing is when I run the index.php from the command line with "php index.html" it shows the correct result. Any help..? Thanks, Similar TutorialsI am using shell_exec, and it runs a ping on a server, is there any way to flush the buffer of the shell_exec as the data is getting written to the buffer? Because I sometimes ping a site 10 times and nothing get written until the function finishes, so is there anyway to write out the output as soon as it is available? btw, this isn't only for doing a ping it is for other things as well. I am wanting to create a basic product listing page for a product category called "Belts". My latest attempt was this, but I got an error: PHP Code: Code: [Select] $query = "select * from products"; $result = mysql_query($query); while($row=mysql_fetch_assoc($result)) { print ".$row['name'] where category = 'Belts'.$row['colour'] where category = 'Belts'"; } Quote PHP Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING This is what my MySQL table looks like: http://i54.tinypic.com/2j1si8w.png I image what I am trying to do will print "Somename Black, ProductName2 Brown"? I'm not really interested in styling at the moment, I just want to see the PHP-MySQL work at the most basic level. I am unsure what the error cosde means. Can anyone see a fault in my code? Hi Guys I cant seem to get unzip to work via php shell_exec this is what I have: Code: [Select] $rworld = $_GET['restore']; $connect->call('remotetoolkit.stopServer',Array()); sleep(12); $nrworld = substr($rworld, 0,-15); $sftp = new Net_SFTP($host); $sftp->login($root_user, $root_pass); $sftp->delete('/root/minecraft/'.$nrworld.'/', true); echo shell_exec("unzip -jo /root/minecraft/saves/$rworld -d /root/minecraft/$nrworld"); sleep(5); $connect->call('remotetoolkit.startServer',Array()); Nothing is returned, it doesn't echo and the command is not executed. If I execute via terminal and change the $variables to the actual names it works fine, and I can ls with shell_exec successfully? Any ideas? Good Friday to everyone! I am writing some PHP code to find certain files and the search the files for a certain string. For example, this is what I have. This works in a LINUX shell environment, yet I need to have it work in PHP since the GUI is web based. Can anyone help? Thanks!

Can anyone help me shell_exec('xcopy C:\xampp\htdocs\test\backup\test.zip "\\fileserver\KT_backup\aback\" /i') I'm trying to call a command using shell_exec by doing the following- Quote shell_exec("C:\\myprogram.exe -t")or die('error'); but that doesn't work, as it returns 'error'. The command "C:\\myprogram.exe -t" works perfect when i call it myself using the cmd.exe but not when i try using it in php with shell_exec. Safe mode is off and i'm using apache as my php webserver. Does anyone know what the problem is here and if not then is there any other ways of executing myprogram.exe in php? This topic has been moved to Other Web Server Software. http://www.phpfreaks.com/forums/index.php?topic=344940.0 Hello all, I am using a shell_exec command like the one below: $output = shell_exec('c:\powershell\powershell.exe get-service'); echo($output); However, when launching the page, the browser will hang with the hour-glass. If i end the powershell.exe process on the web server via task manager, the browser then returns the expected output. Any idea why this is? Other commands, like ipconfig return the correct output and the browser displays "Done" in the bottom left. Any help appreciated. Andrew Hi guys, I'm running the following code: Code: [Select] $result = shell_exec("su user; scp /path/to/file/text.txt user@domain:/path/to/file/text.txt"); Now, the file get's transferred correctly. However, I need to put in place a check to check if the transfer was successful. $result seems to return the same whether the transfer was successful or not. I want to send an email to state whether the file transfer was successful so what do I need to do to check this? Thanks! Debian 5 PHP 5.2.6-1 This script works: <? $output = shell_exec('ls -lart'); echo "<pre>$output</pre>"; ?> This script doesn't work: <? $vars=unserialize(file_get_contents("file.txt")); $output = shell_exec('ls -lart'); echo "<pre>$output</pre>"; ?> I get error: Quote Warning: shell_exec(): Unable to execute 'ls -lart' or Warning: system(): Unable to fork [ls -lart] If file.txt has size 500k, the script works without errors. But my file file.txt has size 30M. Help. NB: oh yeah, the specs: PHP 5.5.9-1ubuntu4.4 Server version: Apache/2.4.7 Ubuntu 14.04-4
OK, this is driving me completely nuts.
Yes, the first problem is, I'm modifying someone else' code, so I'm trying to cludge this, but I don't have the time resources to write the entire application, at least not at this prototype stage.
That said, start_exec() works wonderfully in a standalone, test script, so there's nothing wrong with the server or php mods / version.
The scenario, on clicking an href or button, I want a script to run (it loads files from a remote sftp and also wgets from another server). One would think this isn't much of a problem, so here's where it becomes crazy making.
The code I'm working with is generating the html with print() in the form of print "<html>";
I've tried the usual examples for doing this function, but none of them are using embedded php in embedded html.
So this:
print"<tr><td class=leftsub><div width=100% class=info id=tasks> <a href='windows.php?pull=true'><img src=images/explore.gif width=16 height=16> <u>Pull files from server</u></a><br>does not invoke this:
if ($_GET['pull']) {
# This code will run if ?pull=true is set.
shell_exec('pull.sh');
}
Which is all in the local function.
And this doesn't work either:
print "<img src=images/extract.gif onClick='shell_exec('./pull.sh')' class=button title='Pull files'>";
Nor does this:
print ("<form method='post'><p><button name='button'>Run Perl</button></p></form>");
seem to call this:
if (isset($_POST['button'])) shell_exec('./pull.sh');
There are other ways I could perform the same, even just a cron that pulls and pushes on some regular interval, of couse which is checking to see if the files are open before pulling or pushing, but I'd rather it be on demand.
Am I just going to drive myself nuts without re-writing the entire code? Should I rather just have the requests call a different php script which then inline shell_exec()'s the shell script?
Any insight and feedback is very much appreciated.
Cheers,
Kevin

if(isset($_POST['clearflags'])){
$output = shell_exec('php clearflags.php');
}
The above works fine on my local development server running Debian 10, PHP 7.4 and Apache 2.4.25. clearflags.php is a script that clears various fields in a MySQL database so it's easy to determine if it properly ran or not. On my hosted server however (Bluehost), clearflags.php is never executed. My hosting service swears that SAFE MODE is not on in PHP (which is also Version 7.4). If I call from the command line (php clearflags.php), it runs fine. $output on the hosted server is "Content-type: text/html; charset=UTF-8 " but nothing on my local server where the script is called and runs OK. No entry appears in the error log about this I've also tried using exec() with the same failed result Running phpinfo() on the hosted server shows that disabled_functions are "no value" Thoughts? Edited October 11, 2020 by KenHorseWell I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script: <?PHP ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $RepeatIt = -1; for($g=1; $g!=$RepeatIt+1; $g++) { ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>"; echo $ScanMessage; ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** } ?> At the moment it's returning: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.: So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line. Any suggestions? Thanks. Hi, In my mysql database i have a text input option, in the registration form and edit my details form i have a multiple select dropdown list, which user selects options to populate the text input box, which ultimately populates the text field in the mysql database. All works perfectly. The dropdownlist consists of 3 parts <optgroups> first is current selection (what is the usesr current selection)works fine, The second <optgroup> is existing words, what words we(the site) have given as options, and the third <optgroup> is the words that others have used. This is where im having a small problem. Because its a text field when i call the data from the database, it calls the entire text box as a single option in my select list.. I want to break the words in the text field (at the comma) and have them listed each one as an option in the select list. Example what i need: Words in text box:(my input allows the "comma") word1, word2, word3, word4, word5, word6, How i want them called/displayed: <option value=\"word1\">word1</option> <option value=\"word2\">word2</option> <option value=\"word3\">word3</option> <option value=\"word4\">word4</option> <option value=\"word5\">word5</option> <option value=\"word6\">word6</option> here's my code: $query = "SELECT allwords FROM #__functions_experience WHERE profile_id = '".(int)$profileId."' LIMIT 1"; $original_functionsexperience =doSelectSql($query,1); $query = "SELECT allwords FROM #__functions_experience WHERE profile_id = '".(int)$profileId."' LIMIT 1"; $functionsexperiencelist=doSelectSql($query); $funcexpList ="<select multiple=\"multiple\" onchange=\"setFunctionsexperience(this.options)\">"; foreach ($functionsexperiencelist as $functionsexperienceal) { $selected=""; if ($functionsexperienceals->allwords == $original_functionsexperience) $selected=' selected="selected"'; $allwords=$functionsexperienceal->allwords; $funcexpList .= "<optgroup label=\"Current selection\"> <option value=\"".$allwords."\" ".$selected." >".$allwords."</option> </optgroup> <optgroup label=\"Existing Words\"> <option value=\"existing1,\">existing1</option> <option value=\"existing2,\">existing2</option> <option value=\"existing3,\">existing3</option> <option value=\"existing4,\">existing4</option> <option value=\"existing5,\">existing5</option> <option value=\"existing6,\">existing6</option> </optgroup> <optgroup label=\"Others added\"> //heres problem <option value=\"".$allwordsgeneral."\">".$allwordsgeneral."</option> </optgroup>"; } $funcexpList.="</select>"; $output['FUNCEXPLIST']=$funcexpList; The result im getting for optgroup others added: word1, word2, word3, word4, word5, how can i get it like this: <option value=\"word1\">word1</option> <option value=\"word2\">word2</option> <option value=\"word3\">word3</option> <option value=\"word4\">word4</option> <option value=\"word5\">word5</option> <option value=\"word6\">word6</option> Hi , I have one question .. Can I split showing of content of dynamic list in 2 parts , when I echo list in code .. Code: [Select] <?php // Run a select query to get my letest 8 items // Connect to the MySQL database include "../connect_to_mysql.php"; $dynamicList = ""; $sql = mysql_query("SELECT * FROM products ORDER BY date_added DESC LIMIT 8"); $productCount = mysql_num_rows($sql); // count the output amount if ($productCount > 0) { while($row = mysql_fetch_array($sql)){ $id = $row["id"]; $product_name = $row["product_name"]; $price = $row["price"]; $date_added = strftime("%b %d, %Y", strtotime($row["date_added"])); $dynamicList .= '<table width="100%" border="2" cellspacing="2" cellpadding="2"> <tr> <td width="17%" valign="top"><a href="product.php?id=' . $id . '"><img style="border:#666 1px solid;" src="inventory_images/' . $id . '.jpg" alt="' . $product_name . '" width="77" height="102" border="2" /></a></td> <td width="83%" valign="top">' . $product_name . '<br /> $' . $price . '<br /> <a href="product.php?id=' . $id . '">View Product Details</a></td> </tr> </table>'; } } else { $dynamicList = "We have no products listed in our store yet"; } mysql_close(); ?> Code: [Select] <p><?php echo $dynamicList; ?><br /> </p> It works ok, and putting my files, everything works, but when I put 8 pictures with price and other details, it just show one image with details and another image below with details, and the third image below and so on .. Can I split dynamic list to show 4 images with details on the left side and 4 on the right side? Thank you in advance for help , if is possible Hi, I use the following code to create a select menu from an array of options stored in LISTS.php: include 'LISTS.php'; print('<select id="from" name="from">'); foreach ($langList as $lang) {printf('<option %s>%s</option>', ($from1 == $lang ? 'selected="selected"' : ''), $lang); } echo '</select>'; where LISTS.php includes the following: $langList = array(' ','English', 'French', 'German', 'Dutch', 'Spanish'); This works great, but now I want to do something similar with a checkbox list, where each checkbox has an associated 'onchange' javascript function and I'm getting pretty stuck. My checkbox list is of the following form: Code: [Select] <html> <ul style="height: 95px; overflow: auto; width: 200px; border: 1px solid #480091; list-style-type: none; margin: 0; padding: 0;"> <li id="li1b"><label for="chk1b"><input name="chk1b" id="chk1b" type="checkbox" onchange="function1('chk1b','li1b')">Option1</label></li> <li id="li2b"><label for="chk2b"><input name="chk2b" id="chk2b" type="checkbox" onchange="function1('chk2b','li2b')">Option2</label></li> //etc. </ul> </html> What I want to do is have 'Option1', 'Option2', etc. stored in an array in LISTS.php and have a PHP script that populates the checkbox list accordingly, in a similar manner to my select menu above. I can't work out how to get the ID of the next <li> and the next <input> in the list to go up by one each time, e.g. 'li1b' then 'li2b', 'li3b', etc. Could someone pls help me out? Thanks! Is there a way to take data that is listed like a,b,c,d,e and turn that into an unordered list? Basically, I'm going to have a list of schools that will be listed with comma separators. I'll print that data out in two places, one will be printed as it's in the database. The other I would like to echo as an unordered list. How hard would something like this be? I have a database with all my users. I need an empty list and when a user clicks a button "Add me to the list" they are added to the first position in the list Slots 1. Tom 2. 3. 4. 5. Later, Jerry wants to be added to the list. So this happens Slots 1. Jerry 2. Tom 3. 4. 5. More people join the list 1. Bob 2. John 3. Jerry 4. Tom 5. Tom gets upset clicks the same button to join the list again, and he's bumped back up to first place. Slots 1. Tom 2. Bob 3. John 4. Jerry 5. Is this possible? And is so, how would I go about getting started on such a thing? I've been using PHP for about a year and a half. Hello there, this is a really noob question, but I've no idea on how to make it work without making everything messy and crappy. I have one SQL table called categories, and another called subcategories. Inside the subcategories table there's a field named 'parent' that will link it to the correspondent category, so it should look something like this in html: Code: [Select] <ul> <li>Category <ul> <li>Subcategory</li> </ul> </li> </ul> Would you please give this poor guy a hand? =) |
