    PHP: blank page

    in PHP Coding Help

    Posted

    elloo,

     

    i have php script that works fine on a dev server however on staging server it is a blank page. i have set 'error_reporting(E_ALL) ' and ini_set('dsiplay_errors', 1) however only information i get is some notices and no fatal errors.

     

    i'm aware that php stops executing if there is a fatal error (and appears as blank screen), is there some sort of directive in 'php.ini' which stop php from executing when there are notices. 

     

    thanks in advanced

    Need help to understand this code

    elloo,

     

    i saw this code today and it struck some interest in me 'cause i had not seen this style of coding in foreach statement before.

     

    class Test
  {
          public $testString = "value";
          public $testString1 = "value1";
          private $testString2 = "value2";
  
          public function &do_something()
          {   
                  eval('$rtn=new ' . get_class($this) . ';');

                  foreach($this as $prop => $val)
                  {   
                          $rtn->$prop=$val;
                  }   
  
                  return $rtn;
          }   
  }
$obj = new Test();
print_r($obj->do_something());

     

    i'm tiny bit baffled by the line

     

    $rtn->$prop=$val

     

    what does the function &do_somthing() do?

     

    many thanks in advance

    i had a php test today and had to find what was wrong with the following regex

     

    preg_match('/^(?:ftp://)?([^/]+)@i');

     

    my answer

     

    preg_match('/^(?:ftp:\/\/)?([^/]+@/i');

     

    can anyone tell me if i'm correct or not.

     

    and just for understanding, can anyone explain to me what this means (?:ftp://)?([^/]+)

    Please help- XML & XSLT

    elloo,

     

    I'm new to XML and XSLT and I've thought to learn more about it by trying do something basic. In this exercise I try to query the company.xml file using xpath and trying to save the result in result.xml.

     

    When I run my code I get this in result.xml:

    <?xml version="1.0" encoding="UTF-8"?>
<annual>
<company>
	<turnover id="2001">100,000</turnover>
	<turnover id="2002">200,000</turnover>
	<turnover id="2003">300,000</turnover>
	<employee id="001">Dicovery</employee>
</company>
<company>
	<turnover id="2001">300,000</turnover>
	<turnover id="2002">300,000</turnover>
	<turnover id="2003">400,000</turnover>
	<employee id="002">World</employee>
</company>
</annual>

     

    However my output should be this in result.xml

    <?xml version="1.0" encoding="UTF-8"?>
<annual>
<company>
	<turnover id="2001">100,000</turnover>
	<turnover id="2002">200,000</turnover>
	<turnover id="2003">300,000</turnover>
	<employee id="001">Dicovery</employee>
</company>
</annual>
