Class: PHPShorthand

[line 55]
Converts a shorthand code syntax into PHP code. The syntax is as follows:

Case-insensitive keywords are replaced by their respective operators. These include:

• AND becomes "&&"
• NOT becomes "!"
• OR becomes "||"
• GT becomes ">"
• LT becomes "<"
• GE becomes ">="
• LE becomes "<="
• NE becomes "!="
• NEQ becomes "!=="
• EQ becomes "=="
• EQQ becomes "==="
• MOD becomes "%"
• X becomes "*"
• PLUS becomes "+"

In addition to this, the following translations happen:

• HTML entities for "<" and ">" are converted into their proper symbols
• "." is converted to "->"
• "_" is converted to "."
• "->" with a space on either side of it is converted back into a "."
• Object references are converted to $GLOBALS['object']->property
• Single- and double-quoted strings are handled as special cases and are not transformed.
• [key] array indexes are expanded to their quoted form of ['key']

Here are some examples of the conversion process:

• 
  1     foo.bar ('foo.bar')

  becomes

  
  1     $GLOBALS['foo']->bar ('foo.bar')

• 
  1     not isset (someArray[keyname])

  becomes

  
  1     ! isset ($GLOBALS['someArray']['keyname'])

• 
  1     foo.bar ge bar.foo and not empty (foo.asdf)

  becomes

  
  1     $GLOBALS['foo']->bar >= $GLOBALS['bar']->foo && ! empty ($GLOBALS['foo']->asdf)

Additionally, you can use the replaceGlobals() method to expand object references to refer to an alternate source, or even to add regular expression replacements to the list of existing syntax transformations, for example:

1     <?php
2     
3      $sh = new PHPShorthand ();
4      $sh->replaceGlobals ('mypackage->private_register');
5      echo $sh->transform ('foo.bar ()');
6     
7      ? >

This will output:

1     $mypackage->private_register['foo']->bar ()
