  • How to catch a division by zero?

    - by Cristian Castiblanco
    I have a large mathematical expression that has to be created dinamically. So, for example, once I have parsed "something" the result will be a string like: "$foo+$bar/$baz";. So, for calculating the result of that expression I'm using the eval function... something like this: eval("\$result = $expresion;"); echo "The result is: $result"; The problem here is that sometimes I get errors that says there was a division by zero, and I don't know how to catch that Exception. I have tried things like: eval("try{\$result = $expresion;}catch(Exception \$e){\$result = 0;}"); echo "The result is: $result"; Or: try{ eval("\$result = $expresion;"); } catch(Exception $e){ $result = 0; } echo "The result is: $result"; But it does not work. So, how can I avoid that my application crashes when there is a division by zero?

  • search array and get array key

    - by SoulieBaby
    Hi all, I have an array, which I'd like to search for a value in and retreive the array key if it exists, but not sure how to even go about doing that. Here's my array: Array ( [hours] => Array ( [0] => 5 [1] => 5 [2] => 6 [3] => 6 [4] => 8 [5] => 10 ) ) So I'd like to search the hours array for 10, if 10 exists in the array, I want the key (5) to be returned. If that makes sense? Am trying to do it dynamically so the search string (10) will change, but I figure if I can get it working for number 10, I can get it working with a variable number :)

  • Query for props list with or without values

    - by vitto
    Hi, I'm trying to make a SELECT on three relational tables like these ones: table_materials -> material_id - material_name table_props -> prop_id - prop_name table_materials_props - row_id -> material_id -> prop_id - prop_value On my page, I'd like to get a result like this one but i have some problem with the query: material prop A prop B prop C prop D prop E wood 350 NULL NULL 84 16 iron NULL 17 NULL NULL 201 copper 548 285 99 NULL NULL so the query should return something like: material prop_name prop_value wood prop A 350 wood prop B NULL wood prop C NULL wood prop D 84 wood prop E 16 // and go on with others rows i thought to use something like: SELECT * FROM table_materials AS m INNER JOIN table_materials_props AS mp ON m.material_id = mp.material_id INNER JOIN table_materials_props AS p ON mp.prop_id = p.prop_id ORDER BY p.prop_name the problem is the query doesn't return the NULL values, and I need the same prop order for all the materials regardless of prop values are NULL or not I hope this example is clear!

  • cakephp and SQL_CALC_FOUND_ROWS

    - by Lizard
    I am trying to add the SQL_CALC_FOUND_ROWS into a query (Please note this isn't for pagination) please note I am trying to add this to a cakePHP query the code I currently have is below: return $this->find('all', array( 'conditions' => $conditions, 'fields'=>array('SQL_CALC_FOUND_ROWS','Category.*','COUNT(`Entity`.`id`) as `entity_count`'), 'joins' => array('LEFT JOIN `entities` AS Entity ON `Entity`.`category_id` = `Category`.`id`'), 'group' => '`Category`.`id`', 'order' => $sort, 'limit'=>$params['limit'], 'offset'=>$params['start'], 'contain' => array('Domain' => array('fields' => array('title'))) )); Note the 'fields'=>array('SQL_CALC_FOUND_ROWS',' this obviously doesn't work as It tries to apply the SQL_CALC_FOUND_ROWS to the table e.g. SELECTCategory.SQL_CALC_FOUND_ROWS, Is there anyway of doing this? Any help would be greatly appreciated, thanks.

  • free geolocation geoip, are they viable?

    - by brett
    I'm trying to get a visitor's location based on their IP, pretty common stuff. My research so far shows that there's a database from MaxMind that costs $370 + $90/month... not the type of cost I can afford. Then there's a free version called GeoLite City. Anyone used these before? Drop a quick line here please. Why is one free and the answer so expensive. Is the free one usable, is it not as accurate, what's the catch? P.S. Any other suggestions are welcome.

  • Best way to fetch remote RSS through authenticated proxy and parse it

    - by grajea
    I'm trying to get a remote RSS through proxy and parse it. I'm using magpierss, but it doesn't allow reaching internet through a proxy (or I don't know how to do it). I assume the option is to, first, fetch the rss with curl functions, that allows proxy authenticating, but .... are there any class to do this in a easy way, or ... does magpie support using proxy, and how? Thanks in advance.

  • preg_replace to capitalize a letter after a quote

    - by Summer
    I have names like this: $str = 'JAMES "JIMMY" SMITH' I run strtolower, then ucwords, which returns this: $proper_str = 'James "jimmy" Smith' I'd like to capitalize the second letter of words in which the first letter is a double quote. Here's the regexp. It appears strtoupper is not working - the regexp simply returns the unchanged original expression. $proper_str = preg_replace('/"([a-z])/',strtoupper('$1'),$proper_str); Any clues? Thanks!!

  • Mapping Absolute / Relative (Local) Paths to Absolute URLs

    - by Alix Axel
    I need a fast and reliable way to map an absolute or relative local path (say ./images/Mafalda.jpg) to it's corresponding absolute URL, so far I've managed to come up with this: function Path($path) { if (file_exists($path) === true) { return rtrim(str_replace('\\', '/', realpath($path)), '/') . (is_dir($path) ? '/' : ''); } return false; } function URL($path) { $path = Path($path); if ($path !== false) { return str_replace($_SERVER['DOCUMENT_ROOT'], getservbyport($_SERVER['SERVER_PORT'], 'tcp') . '://' . $_SERVER['HTTP_HOST'], $path); } return false; } URL('./images/Mafalda.jpg'); // http://domain.com/images/Mafalda.jpg Seems to be working as expected, but since this is a critical feature to my app I want to ask if anyone can spot any problem that I might have missed and optimizations are also welcome since I'm going to use this function several times per each request.

  • Zend RegEx Validator error message issue

    - by Mallika Iyer
    Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

Thanks!

  • Doctrine unsigned validation error storing created_at

    - by Alex Dean
    Hi, I'm having problems with the Timestampable functionality in Doctrine 1.2.2. The error I get on trying to save() my Record is: Uncaught exception 'Doctrine_Validator_Exception' with message 'Validation failed in class XXX 1 field had validation error: * 1 validator failed on created_at (unsigned) ' in ... I've created the relevant field in the MySQL table as: created_at DATETIME NOT NULL, Then in setTableDefinition() I have: $this->hasColumn('created_at', 'timestamp', null, array( 'type' => 'timestamp', 'fixed' => false, 'unsigned' => false, 'primary' => false, 'notnull' => true, 'autoincrement' => false, )); Which is taken straight from the output of generateModelsFromDb(). And finally my setUp() looks like: public function setUp() { parent::setUp(); $this->actAs('Timestampable', array( 'created' => array( 'name' => 'created_at', 'type' => 'timestamp', 'format' => 'Y-m-d H:i:s', 'disabled' => false, 'options' => array() ), 'updated' => array( 'disabled' => true ))); } (I've tried not defining all of those fields for 'created', but I get the same problem.) I'm a bit stumped as to what I'm doing wrong - for one thing I can't see why Doctrine would be running any unsigned checks against a 'timestamp' datatype... Any help gratefully received! Alex

  • how to store xml structure in a persistence layer?

    - by fayer
    i wonder how i could store a xml structure in a persistence layer. cause the relational data looks like: <entity id="1000070"> <name>apple</name> <entities> <entity id="7002870"> <name>mac</name> <entities> <entity id="7002907"> <name>leopard</name> <entities> <entity id="7024080"> <name>safari</name> </entity> <entity id="7024701"> <name>finder</name> </entity> </entities> </entity> </entities> </entity> <entity id="7024080"> <name>iphone</name> <entities> <entity id="7024080"> <name>3g</name> </entity> <entity id="7024701"> <name>3gs</name> </entity> </entities> </entity> <entity id="7024080"> <name>ipad</name> </entity> </entities> </entity> as you can see, it has no static structure but a dynamical one. mac got 2 descendant levels while iphone got 1 and ipad got 0. i wonder how i could store this data the best way? what are my options. cause it seems impossible to store it in a mysql database due to this dynamical structure. is the only way to store it as a xml file then? is the speed of getting information (xpath/xquery/simplexml) from a xml file worse or greater than from mysql? what are the pros and cons? do i have other options? is storing information in xml files, suited for a lot of users accessing it at the same time? would be great with feedbacks!! thanks!
