Find any questions in strip_tagged($Web_Page)?

[amedhussaini]

Trying to search a $string (just an HTML page grabbed with curl after stripping the tags) for questions.  I thought to look to return content between "What" and "?" inclusive, etc... but no luck so far.

 

Valid questions I'm looking for:

 

"What is the point?"

"what is the point?"

 

I'd like the function to return all results into an array if possible

 

Cheers,

You can try:

 

<?php

$data= <<<eof
What is the point?
eof;

//the i modifier is for case insensitive (so can match in between What and what)
preg_match("~What(.+)\?~Ui", $data, $a);

//the array of matched results...
print_r($a);
?>

newbtophp, I think that will match more than what he wants. Also, maybe preg_match_all would be more useful.

 

What if you have this - "I wonder what he would do after this fails. Do you think think he'll jump off a building?" Try your regexp against that string. Or this one - "Geez, whatever man. Just stop yelling at me. Did I do something that offended you?"

 

I would try:

preg_match_all("#\W\s(?<questions>What [^!?\.]+\?)#i", $str, $results);

Thanks!  This works like a charm.  Ran it on a few test cases... 99% were accurate, came up with a few of these:

 

: What is RSS? )

 

What is the WTO? )

 

Any ideas on further refining it?

 

For now, I will study your regex expression and decipher how you came up with it... this place really is a wealth of knowledge

Try just looping through $results['questions'].

 

foreach ($results['questions'] as $key => $value) {
     echo $value;
}

err, that was silly.. that was part of my print_r output that i mistook for something else.

 

 

thx again fellas.
