easy string counting?

RedDragon

hi,
at my forum people can setup an secure html signature,
and the admin can set the amount of lines the members can use for their signature...

i tried doing it the following:

$a = explode("<br>", $sig);
$b = explode("<br/>", $sig);
$c = explode("<br />", $sig);
$siglines = count($a)+count($b)+count($c);

but the count was always higher than the real number of lines... i guess that is because of the last entry in the array is empty... i was not able to find a solution for this and hope to get some suggestions here 🙂

well in their signature, the new lines would be exactly that. . . newlines ( \n ) not breaks ( )

Here's an example of how to count the lines. If they typed

hello
my name
is bob

That would be 3 lines. Assuming $var equals thier signature, you would have the following code

$var = "hello\n my name is\n bob";

$newlines = explode("\n", $var);

echo count($newlines);

if html is enabled they can also use br tags ... exploding and counting doesnt seem to do the job anyway....

Try

$lines = preg_split('/( )|(<br\/>)|( )/', $sig);

print count($lines);

FYI:
With

$a = explode("<br>", $sig);
$b = explode("<br/>", $sig);
$c = explode("<br />", $sig);
$siglines = count($a)+count($b)+count($c);

and a $sig of "This has breaktags", you have

$a = array('This', 'has<br />breaktags');
$b = array('This<br>has<br />breaktags');
$c = array('This<br>has', 'breaktags');
$siglines = count($a)+count($b)+count($c);
$siglines = 2+1+2;
$siglines = 5;
