The suggestion seems to be to put these above site root but below web root. The first step is to test that the file exists and the result is always FALSE. Question: Why does file_exists always return false? Things tried 1. created directory called "a" (to avoid misspelling) in web root. file_exists("/a/") is false file_exists("/a/info.pdf") is false although the file exists 2. clearstatcache(); before file_exists 3. added allow_url_fopen = on to php.ini in root</p> <pre><code>enter code here clearstatcache(); $full_path = '/a/info.pdf'; // absolute physical path to file below web root. if ( file_exists($full_path) ) { $mimetype = 'application/pdf'; header('Cache-Control: no-cache'); header('Cache-Control: no-store'); header('Pragma: no-cache'); header('Content-Type: ' . $mimetype); header('Content-Length: ' . filesize($full_path)); $fh = fopen($full_path,"rb"); while (!feof($fh)) { print(fread($fh, filesize($full_path))); } fclose($fh); } else die("File does not exist on the server - ."); </code></pre> <p>The else is always followed.

file_exists使用字符串,但不是$ var

<div class="post-text" itemprop="text"> <p>So I'm trying to make a dynamic link page that takes a load of entries, links to an image if it exists, and links to an upload box if it doesn't. For some reason, though, when I pass a variable to file_exists it returns false, even if passing the same location directly returns true. For example:</p> <pre><code>$tempcomp = "dogs/big dogs/misty.puppy.jpg"; if (file_exists($tempcomp)) { echo "YES1"; } clearstatcache(); if (file_exists ("dogs/big dogs/misty.puppy.jpg")) { echo "YES2"; } clearstatcache(); </code></pre> <p>This code returns YES2, even though both statements are identical.

PHP class_exists()失败,代码相同,环境略有不同

<div class="post-text" itemprop="text"> <p>We have a Zend Framework 2 app that's failing on our test environment at <code>Zend\ServiceManager\ServiceManager-&gt;createFromFactory()</code> with "an invalid factory was registered for this instance type" exception.

Both environments are running Ubuntu 12.04 and slightly different versions of PHP 5.3.10. We've tried disabling xcache but this doesn't help.</p> <p>What would cause these very similar environments to generate different result for <code>class_exists()</code>? The rest of the app is working fine, just this call for one particular factory is failing. Namespaces and configurations have been double checked.</p> </div>

array_key_exists(“id”,$ _SESSION)和$ _SESSION ['id]之间的区别;

PHP file_exists()不起作用?

<div class="post-text" itemprop="text"> <p>I am trying to have this script check if an application exists, and if it does, determine whether it is in the "Accepted" or "Denied" section.

PHP array_key_exists不起作用; 数组不是多维的

<div class="post-text" itemprop="text"> <p>I have an array of all the countries in the world as such:</p> <pre><code>$countries = array( "GB" =&gt; "United Kingdom", "US" =&gt; "United States", "AF" =&gt; "Afghanistan", "AL" =&gt; "Albania", "DZ" =&gt; "Algeria", "AS" =&gt; "American Samoa", "AD" =&gt; "Andorra", "AO" =&gt; "Angola", "AI" =&gt; "Anguilla", "AQ" =&gt; "Antarctica", "AG" =&gt; "Antigua And Barbuda", "AR" =&gt; "Argentina", "AM" =&gt; "Armenia", "AW" =&gt; "Aruba", "AU" =&gt; "Australia", "AT" =&gt; "Austria", "AZ" =&gt; "Azerbaijan", "BS" =&gt; "Bahamas", "BH" =&gt; "Bahrain", "BD" =&gt; "Bangladesh", "BB" =&gt; "Barbados", "BY" =&gt; "Belarus", "BE" =&gt; "Belgium", "BZ" =&gt; "Belize", "BJ" =&gt; "Benin", "BM" =&gt; "Bermuda", "BT" =&gt; "Bhutan", "BO" =&gt; "Bolivia", "BA" =&gt; "Bosnia And Herzegowina", "BW" =&gt; "Botswana", "BV" =&gt; "Bouvet Island",); </code></pre> <p>And so on for all countries; I am 100% positive every country is listed properly.</p> <p>I have an application form which stores the result in a file stored on the server. Currently the review page for the application is a basic text version and I am now in the process of putting it into a mock-form for my client to have a more visually appealing method of reviewing applications.</p> <p>So an array named <code>$in_data</code> stores the results that come from the file. This array is structured as such <code>"emergency_medical_insurance" =&gt; "value_user_entered"</code>. Each key is the name of the HTML element it came form and the value is what the user put in.</p> <p>The country select list on the form returns a two-letter code of the country. So what I am trying to do is search <code>$countries</code> with the value of <code>$in_data['country_select']</code> and then return the name of the country.</p> <p><code>echo $in_data['country_select'];</code> returns 'CA' the letter code for Canada and the test country I have entered.</p> <p><code>echo $countries['CA'];</code> returns 'Canada'</p> <pre><code>if (array_key_exists($in_data['country_select'], $countries)){ echo "Country Found"; } else { echo "failed"; } </code></pre> <p>returns nothing.</p> <pre><code>if (array_key_exists('CA', $countries)){ echo "Country Found"; } else { echo "failed"; } </code></pre> <p>Also returns nothing. And when I say nothing I mean nothing, not null, not true, not false; just doesn't even run.</p> <p>My question is simple; how is the code below (taken from the offical PHP manual) which does EXACTLY the same thing my code does, working, but my code won't even return <em>anything</em>?</p> <pre><code>&lt;?php $search_array = array('first' =&gt; 1, 'second' =&gt; 4); if (array_key_exists('first', $search_array)) { echo "The 'first' element is in the array"; } ?&gt; </code></pre> </div>

即使页面中有类,PHP class_exists也没有回显输出

<div class="post-text" itemprop="text"> <p>I'm trying to get a message to display if a class is present, not sure if I've got the right idea with this or not but it doesn't appear to be showing anything even though the class is there on the page.</p> <pre><code>&lt;?php if (class_exists('quote-me')): ?&gt; &lt;?php echo $this-&gt;__('View Quotation'); ?&gt; &lt;?php endif; ?&gt; </code></pre> <p>Can someone let me know if I'm on the right track.</p> </div>


<div class="post-text" itemprop="text"> <p>Is there anyway to know if the autoloader succeeded when calling class_exists?</p> </div>
