  • Check if a symlink has changed

    - by BCS
    I have a daemon that, when it's started, loads its data from a directory that happens to be a symlink. Periodically, new data is generated and the symlink updated. I want a bash script that will check if the current symlink is the same as the old one (that the daemon started with) and if not, restart the daemon. My current thought is: if [[ ! -e $old_dir || $(readlink "$data_dir") == $(readlink "$old_dir") ]]; then echo restart ... ln "$(readlink "$data_dir")" "$old_dir" -sf else echo no restart fi The abstract requirement is: each time the script runs, it needs to check if a symlink on a given path now points to a something other than it did the last time and if so do something. (The alternative would be to check if the data at the path has changed but I don't see that being any cleaner.) My questions: Is this a good approach? Does anyone have a better idea? Where should I put $old_dir?

  • How to make sure the value is reset in foreach loop in PHP

    - by kwokwai
    Hi all, I was writing a simple PHP page and a few foreach loops were used. Here are the scripts: $arrs = array("a", "b", "c"); foreach ($arrs as $arr) { if(substr($arr,0,1)=="b") { echo "This is b"; } } // ends of first foreach loop and I didn't use ifelse here And when this foreach ends, I wrote another foreach loop in which all the values in the foreach loop was the same as previous foreach. foreach ($arrs as $arr) { if(substr($arr,0,1)=="c") { echo "This is c"; } } I am not sure if it is a good practice to have two foreach loops with same values and keys. Will the values get overwritten in the first foreach loop?

  • How do I show the print with AJAX/jQuery?

    - by Doug
    So I'm trying to understand this whole AJAX/jQuery thing. Right now, when I run this PHP script alone, I would have to wait and watch the wheel spin until it's done with the loop and then it will load. while ( $row = mysql_fetch_array($res) ) { postcode_to_storm( $row['Test'] ); $dom = new DOMDocument(); @$dom->loadHTML($result); $xPath = new DOMXPath($dom); $failInvite = 'Rejected'; $findFalse = strpos($result, $failInvite); if ( $findFalse == true ) { $array[$i] = $row['Test']; $i++; echo $array[$i]}; } } Now, how do I use AJAX/jQuery to show echo $array[$i]}; everytime it is invoked instead of waiting for the whole process to complete?

  • Best way to implement a data structure in PHP ?

    - by Double Gras
    Hi, I want to use some kind of data structure in PHP (5.2), mainly in order to not pollute the global namespace. I think about two approaches, using an array or a class. Could you tell me which approach is better ? Thanks $SQL_PARAMETERS = array ( 'server' => '127.0.0.1', 'login' => 'root'); class SqlParameters { const SERVER = '127.0.0.1'; const LOGIN = 'root'; } echo $SQL_PARAMETERS['server']; echo SqlParameters::SERVER;

  • How to line up columns using paste(1)? or how to make an aligned table merging lines in the shell?

    - by nn
    Hi, I want to merge lines such that the merged lines are aligned on the same boundary. UNIX paste(1) does this nicely when lines all meet at the same tab boundary, but when lines differ in size (in the file that lines are being merged into), the text comes out awkward. Example of paste(1) that has the desired effect: $ echo -e "a\nb\nccc\nd" | paste - - a b ccc d Example of paste(1) with undesired effect: $ echo -e "a\nb\ncccccccccccc\nd" | paste - - a b cccccccccccc d Note how the 2nd column doesn't line up. I want 'b' to line up with 'd', which requires an additional tab. Unfortunately I believe this is the limit for the paste utility, so if anyone has any idea of how to get the desired effect above, I'd love to hear it.

  • How do I specify the regular expression to disable the use of underscores after the '@' sign in php for email validation?

    - by Qlidnaque
    Currently the following email in the script validates even though there are no underscores indicated in the second part of the regular expression validation after the '@' sign. How do I make underscores invalid in the second part of the email? <?php $email = 'firstname.lastname@a_aa.bbb.co_m'; $regexp = "/^[^0-9][A-z0-9_]+([.][A-z0-9_]+)*[@][A-z0-9]+([.][A-z0-9]+)*[.][A-z]{2,4}$/"; if (preg_match($regexp, $email)) { echo "Email address is valid."; } else { echo "Email address is <u>not</u> valid."; } ?>

    if running function returns server misconfiguration error function build_path($cid) { $result = array(); $DB = new MySQLTable; $DB->TblName = 'shop_categories'; $where['cat_id']['='] = $DB->CleanQuest($cid); $res = $DB->Select('cat_id,cat_name,cat_parent', $where); if($res !== 'false') { $pid = mysql_fetch_array($res); if($pid['cat_parent'] !== 0) { Echo $pid['cat_parent']; build_path($pid['cat_parent']); } else { Echo $pid['cat_id']; return true; } } return false; } I can't find an error here. Please help. Sorry for disturbing you all. The trouble was in comparison 'if($pid['cat_parent'] !== 0)': $pid['cat_parent'] was a string with int(0) Can i build this function to store full path without using GLOBALS and SESSION vars?

  • index seems to be out of sync for jquery .keydown and .click methods

    - by Growler
    I'd like to navigate images using both keyboard and mouse (clicking left and right arrow images). I'm using Jquery to do this, but the shared imgIndex seems to be off from the .keydown function and the .click function... Whenever .keydown function -- or ++ the imgIndex, isn't that changed index also used in the click function? So shouldn't they always be on the same index? keydown function: <script type="text/javascript"> var imgArray = [<?php echo implode(',', getImages($site)) ?>]; $(document).ready(function() { var img = document.getElementById("showimg"); img.src = imgArray[<?php echo $imgid ?>]; var imgIndex = <?php echo $imgid ?>; alert(imgIndex); $(document).keydown(function (e) { var key = e.which; var rightarrow = 39; var leftarrow = 37; var random = 82; if (key == rightarrow) { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; } if (key == leftarrow) { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; } }); click function: Connected to left and right clickable images $("#next").click(function() { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; }); $("#prev").click(function() { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; }); }); Just so you have some visibility into the getImages php function: <?php function getImages($siteParam) { include 'dbconnect.php'; if ($siteParam == 'artwork') { $table = "artwork"; } else { $table = "comics"; } $catResult = $mysqli->query("SELECT id, title, path, thumb, views, catidFK FROM $table"); $img = array(); while($row = $catResult->fetch_assoc()) { $img[] = "'" . $row['path'] . "'"; } return $img; } ?> Much appreciated! Snapshot of where the script is on "view image.php"

    - by RC
    Hi, Should be a simple one. Database is mydb. One of the columns is mydata. What SELECT query do I need in order to select the top 3 occuring results from mydata, but sorted alphabetically? For example, if my data is this: mydata ====== kilo (x 1 occurrence) lima (x 9 occurrences) golf (x 5 occurrences) echo (x 9 occurrences) zulu (x 8 occurrences) How do I get it to return "echo, lima, zulu", which are the top three frequently occurring entries sorted alphabetically? Thanks! EDIT: Just to add, they need to be distinct entries. Thanks!

  • Shell script syntax error: unexpected end of line

    - by user1557674
    I wrote a simple shell script to check for the existence of a xml file and if it exists, then rename an old xml file to be backup and then move the new xml file to where the old xml file was stored. #!/bin/sh oldFile="/Documents/sampleFolder/sampleFile.xml" newFile="/Documents/sampleFile.xml" backupFileName="/Documents/sampleFolder/sampleFile2.backup" oldFileLocation="/Documents/sampleFolder" if [ -f "$newFile" ] ; then echo "File found" #Rename old file mv $oldFile $backupFileName #move new file to old file's location mv $newFile $oldFileLocation else echo "File not found, do nothing" fi However, every time I try to run the script, I get 4 command not found messages and a syntax error: unexpected end of file. Any suggestions on why I get these command not found errors or the unexpected end of file? I double checked that I closed all my double quotes, I have code highlight :) EDIT: output from running script: : command not found: : command not found: : command not found1: : command not found6: replaceXML.sh: line 26: syntax error: unexpected end of file

    I'm trying to read the contents of a file and simply getting an empty string. The file exists on the server. I've tried some test with the following code and get the true to display: $filename = "includes/blah.php"; $filecontents = file_get_contents($filename, FILE_USE_INCLUDE_PATH); if ($filecontents === false) { echo(":FALSE:"); } else { echo(":TRUE:"); } var_dump($filecontents); The dump displays "string(354)" which is the correct size of the file. What am I doing wrong?

  • preg_match and long strings

    - by aleluja
    Hi, This is the preg_match i am trying to use to find specific text in text file. if (preg_match($regexp,$textFile,$result) > 0) { echo "Found ".$result[0]; } else { echo "Not found"; } However, the result is always Found and nothing more. The result array is empty. Now i read that preg_match can't work with long strings. My text file is about 300KB so thats 300000 characters i guess. I am 100% sure that the searched string is in the text file, and the fact that preg_match function returns value above 0 means it found it, but it didn't place it into the result array somehow. So my question would be, how do i make it work? regexp would be /[specific text]\{(\d*)\}/ so, of course i want to be able to get the number in the parentheses.

  • Doctrine: textarea line breaks & nl2br

    - by Tom
    Hi, I'm pulling my hair out with something that should be very simple: getting line breaks to show up properly in text that's returned from the database with Doctrine 1.2 I'm saving a message: $body = [text from a form textarea]; $m = new Message(); $m->setSubject($subject); $m->setBody($body); $m->save(); Querying the message: $q = Doctrine_Query::create() ->from('Message m') ->where('m.message_id = ?', $id) ->limit(1); $this->message = $q->execute(array(), Doctrine_Core::HYDRATE_ARRAY); In my template: echo $message[0]['body'] ... outputs the text without line breaks echo ln2br($message[0]['body']) ... no difference ... and I've tried every combination I could think of. Is Doctrine doing something to line breaks that's affecting this, or is there something that I'm just missing? Any help would be appreciated. Thanks.

    Well, I'm trying to gzdeflate my code to perform some very low level encryption for distribution, to use with eval(gzinflate('deflated_code')); However whenever I try to inflate the deflated string, it outputs an error. For example: echo(gzdeflate('test')); outputs +I-.? But when I try to echo(gzinflate('+I-.?')); it only outputs Warning: gzinflate() [function.gzinflate]: data error Is there something I'm missing? Why is it outputting this error rather than test?
