In the session section of PHP.ini there is a directive called session.entropy_length . I'm aware that it's used to make the generation of the session id more random. How does it do that? What is the maximum length? What if it's exceeding the bits of the hash in use? session.entropy_length specifies the number of bytes which will be read from the file specified above. Defaults to 0 (disabled). PHP Manual The "file mentioned above" is session.entropy_file 'entropy' for sessions is related to the randomness of session id values 来源： https://stackoverflow.com/questions/34966472/what-does-session

The following line: echo date('d', strtotime('First Saturday August 2015')); prints 08 , which doesn't seem to make any sense because the first occurrence of a day of the week can't be after the 7th. Is it a php bug or a php bug or maybe even a php bug? I don't know... php version: 5.5.19 Update #1: explained below the big difference that a simple word like " of " makes, after I investigated a little in the PHP source code. Update #2: There actually is a documentation page on PHP manual that explains the formats of dates accepted by strftime() . I just was not aware of it until now. Thanks

I have one model string and list of matching patterns. I want to highlight all the matching pattern in given model string even if any words in pattern/model contains punctuation mark. Sample String: Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s

I encountered a strange behavior of Magento 1.8 after changing php version from 5.5 to 7.0. This strange behavior is due to a change in the work function uasort . Source code: <?php $arr = [ "nominal" => [ "before" => ["subtotal", "grand_total"], "after" => [], "_code" => "nominal" ], "subtotal" => [ "after" => ["nominal"], "before" => ["grand_total", "shipping", "freeshipping", "tax_subtotal", "discount", "tax", "weee"], "_code" => "subtotal" ], "shipping" => [ "after" => ["subtotal", "freeshipping", "tax_subtotal", "nominal", "weee"], "before" => ["grand_total", "discount", "tax_shipping",

A simple question motivated by a curiosity, with probably a complex answer: Is it possible to emulate the new PHP 5.5 imagecrop() in earlier versions, like 5.4, by combining other GD functions? Awn.. But without the imagecrop() black line bug , please. :p This should be a drop-in replacement for imagecrop() (without the bug...): function mycrop($src, array $rect) { $dest = imagecreatetruecolor($rect['width'], $rect['height']); imagecopy( $dest, $src, 0, 0, $rect['x'], $rect['y'], $rect['width'], $rect['height'] ); return $dest; } Usage: $img = mycrop($img, ['x' => 10, 'y' => 10, 'width' => 100

Can i upgrade the PHP version under wampserver instead of whole? Because current latest version of wampserver gives 5.4.3 version, but the latest version of php is 5.5.4. How can i upgrade it? EDIT : Wampserver provides either 5.4.3 or older version. What I'm trying to do is Download latest PHP version from php's official site and than copy that into the wampserver.
