String is a type in PHP and it is a series of characters. There are exactly 256 different characters possible. This also implies that PHP has no native support of Unicode.
However I have a good news as well as there is no limitation in string length in PHP (Of course available memory and PHP ini settings can reduce it).
In Picking Up Perl, Bradley Kuhn cites a saying from the Perl community which says, "Perl promotes laziness, impatience and hubris." He explains how lazy programmers don't want to write the same routines repeatedly so they design their code to be reusable as much as possible. Impatient programmers write efficient programs to do work for them and programmers with pride write clean, readable code and share it with others. The PHP Extension and Application Repository (PEAR) brings this philosophy to PHP
The If Statement is a way to make decisions based upon the result of a condition. For example, you might have a script that checks if boolean value is true or false, if variable contains number or string value, if an object is empty or populated, etc. The condition can be anything you choose, and you can combine conditions together to make for actions that are more complicated.
