  • [PHP] Read and write to a file while keeping lock

    - by Znarkus
    Hi! I am making a simple page load counter by storing the current count in a file. This is how I want to do this: Lock the file Read the current count Increment it Write new count Unlock file/close it Can this be done? As I understand it, the file can't be written to without losing the lock. The only way I have come up with to tackle this, is to write a character using "r+" mode, and then counting characters.

Example code: $db = DBCxn::getCxn(); $sql = "SELECT exercise_id, author_id, submission, result, submission_time, total_rating_votes, total_rating_values FROM submissions LEFT OUTER JOIN submission_ratings ON submissions.exercise_id=submission_ratings.exercise_id WHERE id=:id"; $st = $db->prepare($sql); $st->bindParam(":id", $this->id, PDO::PARAM_INT); $st->execute(); $row = $st->fetch(); if($this->total_rating_votes == null) // this doesn't seem to work even though there is no record in submission_ratings???? { ... }

  • Regex to get rid of everything past the first sentence in a string in php

    - by andufo
    I need to get rid of everything after the first dot (if there is more than 1 sentence), but at the same time, cases like e.g. have to be omited. Some line e.g., when people do something. Extra content. Some line (some parenthesis). Extra content. I need to get rid of the "Extra content.". The returning value should be: Some line e.g., when people do something. Some line (some parenthesis). So far I've come with this regex taken from other threads, but it only finds the dots and split the string into an array. preg_replace('/(?<!\.)\.(?!(\s|$|\,|\w\.))/','',$text); Any ideas? Thanks.

  • [PHP] strtr function OS-reltated problem

    - by Casidiablo
    Hello there! I have this funtion that converts all special chars to uppercase: function uc_latin1($str) { if(!defined("LATIN1_UC_CHARS")) define("LATIN1_UC_CHARS", "ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝ"); if(!defined("LATIN1_LC_CHARS")) define("LATIN1_LC_CHARS", "àáâãäåæçèéêëìíîïðñòóôõöøùúûüý"); $str = strtoupper ( strtr ( $str, LATIN1_LC_CHARS, LATIN1_UC_CHARS ) ); return $str; } This function works fine in my development PC (which runs Windows XP)... but, when I test it in the production server (running Redhat Linux) it does not uppercase the string. The string is ISO-8859-1 encoded. How can I make it work in Linux too? Thanks for reading.

  • PHP controllable menubar position

    - by craide
    I'm an admin for a page and I want to give certain users dynamic control of the menubar layout. The ideal would be a page with a list with menu items and arrows pointing up and down with each item and when you click them the item is reordered. I have a pretty basic idea of how I can do it but I would like some suggestions. The items are stored in MySQL and I only need help figuring out how the items should be ordered or numbered and how to re-order them. This probably needs some javascript trickery and I'm not familiar with JS.

  • Handling apostrophes, php and pgsql

    - by running4surival
    For my forms, I'm using pg_escape_string on every field before I insert them into the database. So I get something like firstname='O''reilly'. But when I try to print that out, I get O''reily, 2 apostrophes. Shouldn't it only 1 apostrophe, O'reilly? This isnt a debugging problem, im just wondering if you have firstname='O''reilly', how do you print that so it is just O'reilly instead of O''reilly?

  • PHP array pointer craziness

    - by JMan
    I'm trying to create a "GetCurrentLevel" method that takes a point value as an input and returns what "Level" that corresponds to. I'm storing the Level = Points mapping in an array, but the array pointer is not moving logically when I use it a foreach loop. I've added echo statements for debugging. Here's my class definition: class Levels extends Model { protected $_map = array ( 'None' => 0, 'Bronze' => 50, 'Silver' => 200, 'Gold' => 500 ); public function __construct() { parent::__construct(); } public function GetCurrentLevel($points) { foreach ($this->_map as $name => $threshold) { echo "Level Name: $name<br/>"; echo "Level Threshold: $threshold<br/>"; echo "Current Level: " . key($this->_map) . "<br/>"; echo "Current Threshold: " . current($this->_map) . "<br/>"; if ($points < $threshold) /* Threshold is now above the points, so need to go back one level */ { $previousThreshold = prev($this->_map); echo "Previous Threshold: $previousThreshold<br/>"; echo "Final Level: " . key($this->_map) . "<br/>"; return key($this->_map); } echo "Go to next level <br/>"; } } And here is what I see when I call GetCurrentLevel(60): Level Name: None Level Threshold: 0 Current Level: Bronze //* Looks like foreach immediately moves the array pointer *// Current Threshold: 50 Go to next level Level Name: Bronze Level Threshold: 50 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Go to next level Level Name: Silver Level Threshold: 200 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Previous Threshold: 0 Final Level: None But the "Final Level" should be 'Bronze' since 60 points is above the 50 points needed for a Bronze medal, but below the 200 points needed for a Silver medal. Sorry for the long post. Thanks for your help!
