What does "->" mean

[yacaph]

Hi Experts,

 

I'm fairly new to PHP and have not been able to find any info on "->" as in $this->_Link. Is it an operator? Are there other means of accomplishing the same thing?

 

Thanks,

 

Joseph

I would take a look at classes in PHP.

In Object Oriented speak, it's used to access properties and methods inside an object. But if you've never used objects before, I would give the site in the last post a read and this one too:

It's used to access class methods and properties, and this is used in reference to the current object.

While you may be new to PHP, if you know anything about Visual Basic, javascript or other OOP (Object Oriented Programming), its the same as writing:

 

 

this._Link

or in Excel Macros:

activesheet.select;

Thanks to all for your helpful responses. I can see that since the period was already used for concatenation, something was needed as a class qualifier.
