[SOLVED] Python strong minipulation in PHP??

[PC Nerd]

Hi,

 

I was looking for functions in PHP thaty are similar to the ones on Python.  specicically the way you can "index a string"

 

in python:

variable = "this string"

print variable[0]        -: t

print variable[:5]      -: this

print variable[2:]      -: string

 

from there i can generate random numbers and basically come up with a complete string of random letters - from indexing the characters in the string

 

 

 

How can i do this in PHP.  i want to create a really long unique ID - so that i can use in in a database as email authentication -- except i want to create my own.

 

 

hw can i create this indexing

 

thanks

I love string slicing in Python as well, but for PHP you'll have to do with substr() or accessing a single character at a time:

echo $string[4];

** so i can jsut use a single index in PHP:

 

 

$var = "string";

echo $var[0]      ->> "s"

 

???

Yes, you can do

echo $string{4};

as well, but it's deprecated as of PHP6.

php6!!!!!! im just getting friends to move form version 4 - already!!!

 

 

lol,thnkx

 

 

btw how woudl you do it in php 6 - just out of interesnt????

Using square brackets. Accessing it like an array like I did in the first example. It's only the curly brackets (second example) which are being deprecated. Then again, there is always substr() for getting longer parts than just a single character.
