PHP - File_exists Returning True Even Though The File Patently Doesn't Exist!
*delurk! It had to happen sooner or later!*
OK, I am totally and utterly stumped. I have this script: $this->clear_cache ($this->cache_dir, $this->cache_time); if ($this->cache_time > 0) { $current_page = $_SERVER ['REQUEST_URI']; $current_page_encoded = base64_encode($current_page); $current_page_path = $this->cache_dir . $current_page_encoded; if (file_exists($current_page_path)) { // see if there is still a file with the name of the current request URI after cache cleared $content = file_get_contents ($current_page_path); return $content; } } Basically, it is for checking if there is a cached version of the page before running the rest of the script, using the REQUEST_URI as the identifier. So it calls a function to clear the cache, which works fine (and I've tried just deleting the cache files manually anyway). Then it checks if we are even caching, i.e. if cache time is greater than 0. Then it uses the BASE64-encoded REQUEST_URI (under which name the file would have been cached previously) to check if a file with that name still exists in the cache dir, and if so loads it. Now, this works perfectly with a url like: mysite/myscript/mysubpage But when the page has parameters, like: mysite/myscript/mysubpage?search=widgets the file_exists function returns TRUE, even though the directory is empty. I did do a clearstatcache(); but it made no difference and anyway, it wouldn't explain why the URI with query string would fail while the regular one would not. And even if something is wrong with my code elsewhere, the fact is it is returning TRUE for a non-existent file. Can someone prevent my slide into insanity?! Similar TutorialsI have a script that uses simplexml_load_file to download weather xml files. It works great except when the file doesn't exist. The server returns an HTML page when the xml file isn't available but the title is something.xml. How can I check to be sure it is an xml file and handle the error when it isn't. I have tried file_exists and access the return code (it's always 200). Can I access the doctype and determine if it HTML or XML? I'm trying to do a simple image upload. It works fine on my local server but i'm moving all my files to my production server and some files i attempt to upload, via an html form, don't register. The $_FILES variable doesn't exist sometimes. I think its because of the file size but i'm not sure. The form has two inputs: "title" and "userfile". I can put something in the title and attempt to upload a small excel file and both $_POST and $_FILES exist but if i do a larger image file both $_POST and $_FILES don't even get set. I did an "echo ini_get('post_max_size');" and i get "8M". The image i'm attempting to upload is only 0.34M so i should be good there. I've replaced the actual upload script with this, which is how i found out the variables only get set sometimes Any suggestions would be much appreciated. Code: [Select] <?php echo "Upload: " . $_FILES["userfile"]["name"] . "<br />"; echo "Type: " . $_FILES["userfile"]["type"] . "<br />"; echo "Size: " . ($_FILES["userfile"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["userfile"]["tmp_name"]; echo "<hr><pre>"; print_r($_POST); echo "</pre><hr>"; echo "<pre>"; print_r($_FILES); echo "</pre>"; And how can I make it so if it does already exist, it doesn't over-write information already in it? Thanks I have a statement $account = $_SESSION['account_id']; $postedby = $account_id; /*both echo out to the same number*/ if($account == $postedby){ echo "DELETE BUTTON"; } i echo'ed out both $account and $postedby and both return 1 but the if statement fails to read as true. HELP!!! thanks in advance! I am trying to take all the information from $results and input it into a text file, sometimes we get duplicates in $results so I want to check the text file for the entry before writing it in so we don't get duplicates in the text file. However inarray keeps returning false, even when I echo out the two arrays and they match? Code: [Select] $myfile = "complete.txt"; foreach ($results['info'] as $data) { $output=$fields['firstname']."|".$record['lastname']."|".$record['address']."|".$record['number']."\n"; $handle = fopen($myfile, "r"); $contents = fread($handle, filesize($myfile)); fclose($handle); $list = array(); $list = explode("\n",$contents); $list = array_map("trim", $list); $current = $output; echo in_array($current,$list) ? $current.' exists' : $current.' does not exist'; if (in_array($current,$list)) { print "duplicate"; } else { if($file=fopen($myfile, "a")) { //open file for writing fwrite($file, $output); //write to file } } } I had some code that I'm pretty sure used to work, basically something like the below. Code: [Select] if (preg_match("/[a-zA-Z0-9]+/", $_POST['title'])) { echo $_POST['title'];exit(); } Now i just don't get why it always returns true, even when entering special characters like "!#%?".. The only thing which comes to mind, is that i recently made a move to UTF-8.. I have an IF statement that is constantly returning TRUE, even when it shouldn't be. Basically it checks if an array is empty. Code: [Select] <?php $error = array(); //No blanks if ($street_addr == "" || $city == "" || $state == "" || $zip == "" || $phone1 == "" || $phone2 == "" || $phone3 == "" || $county == "") $error[] = "You left something blank!"; //validate zip if(!preg_match("/^[0-9]{5}$/", $zip)) $error[] = "The ZIP code must be a 5-digit number."; //validate phone number if (!is_numeric($phone1) || !is_numeric($phone2) || !is_numeric($phone3)) $error[] = "Phone can only contain digits"; if (strlen($phone1) < 3 || strlen($phone2) < 3 || strlen($phone3) < 4) $error[] = "Invalid phone number"; $count_errors = count($error); if ($count_errors > 0){ echo "ERROR:<br />"; foreach ($error as $err){ echo "-$err<br />"; } } else { //Other code } ?> So the first part of the IF statement is always executing. $count_errors DOES return 0 when printed out. Any help would be greatly appreciated. Thanks! Here is my code so far (I say it's PDO but it pretty much isn't. What is the object here? The database connection? LOL!); $sql = " SELECT SUM(IF(`sent` != 'N' , 1 , 0 )) as 'Emails Sent', SUM(IF(`completed` NOT IN('N','paper') , 1 , 0 )) as 'Completed Electronically', SUM(IF(`completed` = 'paper' , 1 , 0 )) as 'Completed Manually', SUM(IF(`completed` != 'N' , 1 , 0 )) as 'Total Number Completed', SUM(IF(`remindercount` = '1' , 1 , 0 )) as 'Reminder Sent Once', SUM(IF(`remindercount` = '2' , 1 , 0 )) as 'Reminder Sent Twice', SUM(IF(`remindercount` = '3' , 1 , 0 )) as 'Reminder Sent Thrice' FROM `tokens_$survey_id` "; $statement = $dbh->prepare($sql); $statement->execute(); $result = $statement->fetch(PDO::FETCH_OBJ); foreach($result as $key => $value) { echo "<tr> <td>$key</td> <td>$value</td> </tr>"; }This is all well and good if the tokens_$survey_id table is actually there. Sometimes, for a genuine reason, there won't be a tokens table for that particular survey. How do I account for this? At the moment I get an error.. Warning: Invalid argument supplied for foreach() in /var/www/html/index.php on line 149I tried this but I am not satisfied this is correct; if(!$result) { die(); }I don't want the code to die! If I take out the die() statement then this if is ignored for some reason I don't understand. I'm just trying to find out if php has the ability to check if any file exists, with only part of the filename given.. I have this path: if (file_exists($dir.'/'.$c_file.'/templ_*')) { I added a little star.. That star represents whatever the rest of that file is named for this example.. It could be anything.. So can php match any files that start with "templ_", and say that it does or does not exist?? Thanks I want to get suggested keywords from yahoo api service. When xml file is empty (no keyword), it gives error. To resolve this problem I used this code: if (file_exists('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2')) { $xmlmetades = simplexml_load_file('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2'); } Since it is not a normal .xml file, it is always considered no file, and return nothing. I'm printing some mysql results to a table and sometimes I have rows with no results so they never get counted... which results in an ugly looking parenthesis on my page with nothing it (). For these times, I'd like to print a zero. How can I rewrite the following to achieve this? Code: [Select] if($row['mycount'] does not exist) { $row['mycount'] = '0'; } I guess I'm just stupid cause it seems like every time i get stuck and i post on here and its gets answered in less than 30 min.'s and i keep getting stuck! Here my script... function scoring($user){ $query = "SELECT Game_ID, Pick FROM Cfb WHERE User_ID= 1"; $result = mysql_query($query); $query1 = "SELECT Game_ID, Pick FROM Cfb WHERE User_ID= $user"; $result1 = mysql_query($query1); $affected = mysql_num_rows($result); for($i=0; $i< $affected; $i++) { $scores =mysql_fetch_assoc($result); $scores1 =mysql_fetch_assoc($result1); $main = array_diff_assoc($scores,$scores); $me = array_diff_assoc($scores, $scores1); $m = count($me); $m1 = count($main); if ($m == $m1){ $points += 1; }else{ $points += 0; } } echo '<br />'; echo '<br />'; echo $user; echo '<br />'; echo $points; echo '<hr />'; } $sql="SELECT id FROM users WHERE approved=1 AND user_level !=10"; $result=mysql_query($sql); while($row = mysql_fetch_object($result)) { $ids[] = $row->id; } print_r($ids); Alright heres what this script does... The script has a function that scores 1 individual user for his/her choices. Then I'm getting the user_ids from the users table at the bottom. Taking those and plugging them back into the function to score all the users at one time. Problem... Not all users will make picks. So how do i break the script in the function if that user_id is not is the CFB table attached to picks I have 2 tables im using Cfb and users users controls user info such as id # name username ect.. Cfb controls the picks. When a user makes there selection it stores there User_ID, Game_ID, and Pick So not all user ids are in the Cfb table. So if the script tries to input a user id thats not in the Cfb table it needs to break. Right now it just screws everything up! So how can i make it break that way? Thanks for any help Delete. I'm working on a WordPress theme and I'm trying to build in a simple if statement which will check if the user has add his own logo into the images folder if he doesn't then the name of the blog will appear as normal text in place of the graphic logo. This is how it looks like: <?php $logo_dir = get_template_directory_uri() . "/images/logo.png"; if (file_exists($logo_dir)) { ?> <li><img src="<?php bloginfo ('template_directory'); ?>/images/logo.png" alt="<?php bloginfo('description'); ?>" /></li> <?php } else { ?> <li id='blog_name'><a href="<?php bloginfo('url'); ?>"><?php bloginfo('name'); ?><font>*</font></a></li> <?php } ?> I've echo'd out $logo_dir, the URL is correct, but still for some reason it's seeing it as if there would no file exist. If I turn it around into !file_exists then the graphic logo WILL show up. So it's always seeing it as non-existent. Any ideas why this could be or am I using this function in a wrong fashion? As far as I've understood the PHP manual, this is the correct way of using it. First time post, be easy on me...
I'm using preg_match_all to return an array with all the matches. I know I'm missing something fundamental, but I either keep looking past it or am more screwy than I know.
Sample String

Hi, My site was working fine, but I just switched servers/web hosts and now I'm getting the following errors (in blue). The thing is, I don't get the error if I try to run the query loop after just using 'mysql_select_db' once, but if I use it again to select a different database and then run the query loop, I start getting the error. Code: [Select] mysql_select_db ("database1", $mysql_con); $mysql_query = mysql_query ("SELECT ID FROM someTable1", $mysql_con); $someVar1 = 0; while ($mysql_array = mysql_fetch_array ($mysql_query)) { $someVar1 ++; } ////// The above code gives me no error. But If I then try to select a different database and run a loop in the same way (in the same file), I start getting the below error... mysql_select_db ("database2", $mysql_con); $mysql_query = mysql_query ("SELECT ID FROM someTable2", $mysql_con); $someVar2 = 0; while ($mysql_array = mysql_fetch_array ($mysql_query)) { $someVar2 ++; } Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in /home/snubby5/public_html/coozymcmillan.com/view.php on line 86 So I looked it up and somewhere it told me to add some extra code to handle errors better: Code: [Select] if ($mysql_query === FALSE) { die (mysql_error ()); // TODO: better error handling } But when I do that, I get a different error: Table 'database1.someTable2' doesn't exist It doesn't seem to recognize that I switched databases, and it says 'database1.someTable2' doesn't exist (because it doesn't), when really it should be checking for 'database2.someTable2' (which exists). So to reiterate, I can run the query loop fine after selecting database1, but after that if I select database2, it either gives me the first error, or If I add the 'die' code it gives me the second error. Thanks much! PS: I can get it working if I put everything into one database, but I have multiple websites (which sometimes need to call eachothers' databases) and it would be a huge hassle to cram them all into one database unless I have to. Hi all My code give this: <b>Warning</b>: file_exists(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/clients/........ I get the tmp folder and check for its existanse and whether it is writeable
$t=sys_get_temp_dir(); Both gives no which is fine, I can process that. I do it to avoid the output above, but I still get that. How should I check for allowed paths? This runs on several systems where I cannot access php.ini or other system stuff.
Hi all, I want to make a script that identifies if an image JPG file exists. Would somthing like this work? <?php $file = "images/image.jpg"; if ($file > 0) { echo "file exists"; } else { echo "no file"; } ?> So in my last thread I was working on checking if a file was there...I resorted to something not in the library and used $pic_exists_jpg = fopen($jpg_path,'r'); $pic_exists_jpeg = fopen($jpeg_path,'r'); $pic_exists_gif = fopen($gif_path,'r'); $pic_exists_png = fopen($png_path,'r'); if ($pic_exists_jpg != '0') { $jpg_test = '1'; } elseif ($pic_exists_jpg == '1') { $jpg_test = '2'; } elseif ($pic_exists_jpg == '0') { $jpg_test = '2'; } elseif ($pic_exists_jpeg != '0') { $jpeg_test = '1'; } elseif ($pic_exists_gif != '0') { $gif_test = '1'; } elseif ($pic_exists_png != '0') { $png_test = '1'; } now for some reason php is being a poo and no matter what returning that there is a file there. no matter what method i use be it fopen or file_exists or anything else, it saying I have a file in that directory BUT I DO NOT! THERE IS NOT ONE OF THOSE FILES. I know I have my paths right because If I echo them directly I get the picture...what the heck?! |
