Limiting HTML char count code with php.

[Sims]

Hi,

I know how to limit the number of characters using substr,
(http://uk.php.net/manual/en/function.substr.php).
But when using html that is not going to work because of all the possible
tags, (anchor, image, table...etc).

for example, if I have some text...
$text = "<a href='somelonnn nnnngg'>this is a small text</a>";

I want to create a function to make sure that there is not more than 10
chars displayed.

but if I use

$text1 = substr($text, 0,10 );
i get $text1= "<a href='s";

where I would like to get

$text = "<a href='somelonnn nnnngg'>this is a </a>";
^^ only 10
chars.

How could the above be achieved?

Many thanks.

In essence: Pick out the bit between the single quotes and check it's
length.

All the stuff you need is at:

http://www.php.net/manual/en/ref.strings.php

(see explode, strlen)

BTW what are you planning doing it it's too long?

Sorry I am not sure I follow what you are saying.
I want the output text length to be limited not the tags.

Well if I can limit the number of characters it is easier to display.
for example if I do not want a table to have more than 50 chars then I could
truncate them, but I only want to truncate characters that will be
displayed.
not the html tags that are not displayed.

In my example given I want to limit to 10 the number of characters
displayed,
but not the tags should be excluded.

$text = "<a href='somelonnn nnnngg'>this is a </a>";
^^ only 10
chars

As the quote goes.... 'I wouldn't go there from here'.

Why are you parsing the finished href? Can't you trim the text before
building the href?

Alternatively use regular expressions to parse out the bit between the tags.

Or, use strip_tags().

That function name is a misnomer; it ought to be renamed:
strip_everythin g_between_lesst han_and_greater than.

:-/ I'm one third serious.
