Random character

[jeeva]

hi frnds,

 

can i generate random character by using php?. i can generate the random number by using rand() function but i can't able to generate the character.

 

is there any function in php for this? any one can help me?

[boo_lolly]

there are <i>plenty</i> of ways to do this. and i mean a LOT. first of all, do you want to generate only one random character? or a long string of random characters?

<pre>
<?php
$lc_letters = range('a', 'z');
$uc_letters = range('A', 'Z');
$numbers = range(0, 9);

$pool = array_merge($uc_letters, $lc_letters, $numbers);

for ($i = 0; $i <= 9; $i++) {
	echo $pool[array_rand($pool)];
}
?>
</pre>

That doesn't make any sense. "The 2 character" what?

Try this:

 

<pre>
<?php
$lc_letters = range('a', 'z');
$uc_letters = range('A', 'Z');
//$numbers = range(0, 9);

$pool = array_merge($uc_letters, $lc_letters);

for ($i = 0; $i <= 1; $i++) {
	echo $pool[array_rand($pool)];
}
?>
</pre>
