Unique ID

[Jaan]

Sometimes you need to create a unique id for something.. i'll show you one really easy way how to create a unique id:

PHP Code:

<?php
echo uniqid(); // This will create a ID what is 13 characters long
?>

Example

PHP Code:

<?php
echo uniqid('', true); // This will create a ID what is 23 characters long
?>

Example

[John]

What is each parameter responsible for? Meaning what happens if i change true to false? and what can i put in the ' ' ?

uniqid syntax is:

uniqid(string prefix, [bool_more_entropy])

so.. if you use this:

PHP Code:

<?php
echo uniqid('', true); // This will create a ID what is 23 characters long
?>

then you can write your ID prefix into ' '.

Example:

PHP Code:

<?php
echo uniqid('codecall', true);
?>

This will create a unique id what looks like this:
Check
Like you see there's prefix+id so there have to be codecall(idHere)

Now those true and false statements

If you use false statement then your id will be 13 characters long, but if you use true statements then this id will be 23 characters long
