[FX.php List] FMPHP API

[DC]

well, strcspn() is another obscure function. i've been coding PHP on  
a daily basis for several years now and i had to look it up! it may  
have a specialized usage and you've certainly demonstrated one  
interesting one ;-) it took me a minute to wrap my head around that one.

But, your best bet for code share-ability, maintainability and  
readability is to know and explore the outer reaches of PHP functions  
but when writing PHP to accomplish basic tasks, use standard PHP  
idioms like list with explode. PHP offers multiple paths to the same  
outcome but if you write code with idiosyncratic idioms you're going  
to run into trouble down the road - with other PHP coders and with  
your own memory.

FYI, the equivalent to FMP's left() function in PHP is substr():

Cheers and happy coding,
