Use Abort to escape from an execution path without reporting an error.

Abort raises a special "silent exception" (EAbort), which operates like any other exception, but does not display an error message to the end user. Abort redirects execution to the end of the last exception block.

1.  <?php
2.         function CheckOperation($Operation, $ErrorEvent)
3.         {
4.             $Done = false;
5.             do
6.             {
7.                 try
8.                 {
9.                   $this->$Operation();
10.                   $Done=true;
11.                 }
12.                 catch (EDatabaseError $e)
13.                 {
14.                     $Action=daFail;
15.                     $Action=$this->callEvent($ErrorEvent, array('Exception'=>$e, 'Action'=>$Action));
16.                     if ($Action==daFail) throw $e;
17.                     if ($Action==daAbort) Abort();
18.                 }
19.  
20.             }
21.             while(!$Done);
22.         }

This function is the Delphi for Windows equivalent for assigned, and in this case, it checks for a variable if assigned to null or not. Note that $var can contain anything, it doesn't check if it's an object or not.

Parameters

This function takes a PHP boolean value and echoes a valid javascript boolean value (true/false) to the output. You can use it when writting PHP code that generates Javascript code so you don't have to mess with boolean values

1.  <?php
2.  
3.  echo boolToStr(($a==1));
4.  
5.  ?>

Parameters

This function is used to automatically extract all javascript code from an HTML chunk, the splitted code is returned in an array, in which the first item (key 0) is the javascript code and the second item (key 1) is the HTML code without the javascript.

1.  <?php
2.    $result=extractjscript($htmlwithjavascript);
3.    $js=$result[0];
4.    $html=$result[1];
5.  ?>

Parameters

This function takes HTML as input, including line breaks and entities, and returns the text in plain text form, by changing
to carriage returns and all entities to their corresponding character.

1.  <?php
2.  
3.  echo htmlToText("this is HTML<br />Including &aacute;&eacute;&iacute;&oacute;&uacute; chars<br />");
4.  // This will produce "this is HTML\nIncluding αινσϊ chars\n"
5.  
6.  ?>

Parameters

Use this function to redirect to a script that is in the same project without worring about host or anything else, as the function calculates the right URI to redirect to.

1.  <?php
2.  
3.  redirect("unit2.php");
4.  
5.  ?>

Parameters

This function first tries to unserialize the $input using the built-in PHP function, and if there is any error, it tries to unserialize using the DBCS safe function __unserialize to try get the value because it may be encoded as DBCS.

Tags:

Parameters

This function takes plain text as input, including carriage returns and non html chars, and returns the text in HTML form, by changing carriage returns to
and all non html chars exchanged by their corresponding entity.

1.  <?php
2.  
3.  echo textToHtml("this is plain-text\nIncluding αινσϊ chars\n");
4.  // This will produce "this is plain-text<br>Incluiding &aacute;&eacute;&iacute;&oacute;&uacute; chars<br>"
5.  
6.  ?>

Parameters

This function allows you to unserialize serialized objects/arrays/variables when working with DBCS (Double Byte Character Sets) because it fixes the length of strings to the real length before unserializing.

If not doing it this way, unserialize will throw an error due incorrect string lengths.
