Finding info in a string

nca

$string = "<TD align='left'><font size="5" face="Arial"><b>Info:</b></font></TD>
<TD><font size="4" face="Arial">Text that I want is right here</font></TD></TR>";

The above is the main string that it works with. Now, how do I make it pull just "Text that I want is right here" out of it, and it is made as $string's value?

Remove all html tags like this...

$string = preg_replace("/<.*?>/", "", $string);

then you have:
$string = "Info: Text that I want is right here";

Ok you want the last part...

list($remove, $string) = explode(":", $string);

then you have:
$string = "Text that I want is right here";

Hi, thanks for the reply.
How do I get it to stop getting stuff after the "info:" and two line breaks?
So if it ends up getting...

asdfasdf fasd fa sdf asd fa sdf asd f asd fasd f
asdfasdf asd f sdaf a sdf as df asd f asdf asdf

zxcvzxcvzcxv zxcv z xcv cx   zxc v zxcv z xcv zxc v
zxcv zxcv zxc vz xcv zxc v zxc v zxc vzxc v zx vc xc

I only want $string to store...

asdfasdf fasd fa sdf asd fa sdf asd f asd fasd f
asdfasdf asd f sdaf a sdf as df asd f asdf asdf

anyone?

instead of bumping, would you let us know what exactly you want?

is the problem that there is more text outside html tags lateron in your string that you don't want to catch? if so, perhaps you could change your example to reflect a realistic scenario that exposes the problem?

What I was trying to say is, if $string's value was 2 paragraphs, how do I get it to drop everything after the first paragraph. I guess I would need to split $string up by paragraphs, and drop everything after the first 2 line breaks???

Again, please tell us what you are trying to accomplish.

Not just this step, but the whole deal!

If you are trying to do a template system where people can change the wording without screwing up the formatting, there is a MUCH easier way...

<?php
$template = "<TD align='left'><font size="5" face="Arial"><b>Info:</b></font></TD>
<TD><font size="4" face="Arial">%inserttext%</font></TD></TR>";

$output = str_replace("%inserttext%", $text_to_insert, $template);

echo $output;
?>

If you are trying to parse the contents of another website, then ignore the example above. 🙂

Ok, lets try this again, this is what the script does...

$string = implode ('', file ('http://domain.com/file.html'));
$string = preg_replace("/\<.*?\>/", "", $string);

Then string now has this as it's value...

Paragraph 1. It has some text.

Paragraph 2. It has some text.

Paragraph 3. It has some text.

Because that is what is left after it removes all html tags.

How would I remove everthing after the first paragraph it has?

So it would end up with just...

Paragraph 1. It has some text.

In other words, how can you tell it to keep everything before the first 2 line breaks.

Thanks for any help guys! 🙂

$paragraph1 = substr($paragraphs,0,strpos($paragraphs,chr(10))-1);
