Preg_match()

blinn_shade · #1 (**permalink**) 05-09-08, 08:12 PM

Hey,

How can I match this:

<h1><font size="2">Any character - + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>

I want to match that but put that in array[0] and then the rest of the content in array[1] but it can only happen at the start of the string variable.

Could someone help me with the pattern using preg_match() please?

You want to match this part only?
Any character - + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, .

or the whole line from <h1> to </h1> ?

The whole line from <h1> any character ; : ' @ etc.. </h1> only once.It will always be at the beginning.

PHP Code:


			

(<h1><font size="2">)(0-9a-zA-Z-@&:;,)(</font></h1>)

?

Code:

(<h1><font size="2">.*?<\/font><\/h1>)

Try:

(<h1><font size="2">(.+)</font></h1>)

Jay's solution works too.

Here is your source code, multiple similar elements:

PHP Code:


			
<?php

$a = <<<HTML

<h1><font size="2">Any character First - + = ' @ / ? > < : 

; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>



<h1><font size="2">Any character Second- + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>



<h1><font size="2">Any ch

aracter Third- + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>



<h1><font size="2">Any character Fourth- + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>



<h1><font size="2">Any character Fifth- + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>



<h1><font size="2">Any character Sixth- + = ' @ / ? > < : ; # @~ & * ( ) ^ %$£ "!¬`, . </font></h1>

HTML;

?>

This will pick up the first one only, even if there is non-word character such as new line, tab etc. :

PHP Code:


			
preg_match("/(\<h1\>)(.|\W)+(\<\/h1\>)/U",$a,$match);



echo "<pre>".htmlspecialchars($match[0])."</pre>";

So if I havethis

PHP Code:


			

'<h1><font size="2">Some product name</font></h1>fghfghfghfghfghfghfgh'

How can I get the rest of the string in an array such as: fghfghfghfghfghfghfgh

I highly recommend downloading something called The Regex Coach, which allows you to work interactively with regular expressions. It's free and it's saved me a ton of time and head-scratching when it comes to figuring out regular expression patterns.
