[SOLVED] How to parse sections?
« on: November 20, 2008, 05:15:03 AM »
I want to know how to parse this... I know there is a way, please help me.
Someone posts:

[1]Section 1[/1]
Blah Blah Blah
[1]Section 2[/1]
Blah Blah Blah
[1]Section 3[/1]

What I want to do is take all the text inbetween the [1]s and [/1]s and put it into an array, like:

$array1 = "Section 1";
$array2 = "Section 2";
$array3 = "Section 3";

Then I need the text to be made into something like this.

[1]Section 1=Section 1[/1]
Blah Blah Blah
[1]Section 2=Section 2[/1]
Blah Blah Blah
[1]Section 3=Section 3[/1]

How can this be done?

Thanks

Well, you could use preg_match to detect all the items between [1] and [/1] and you could then use Str_Replace to find all those variables and replace them. If str_replace doesn't work, try preg_replace instead. The main difference is preg_replace let's you use RegEx. This naturally slows it down so see which one suits your needs

I used:
Code: [Select]
$stuff = preg_match("[1]*[/1]",$pagetext);
To try to put the put the stuff inbetween [1] and [/1] into $stuff as an array but it didn't do anything.  Any Ideas? Did I do it wrong?

i believe [] are control chatacters in regex, and so must be escaped. also, when using preg function i think you have to have an opening/closing character around the string. here i use ~. try this:
Code: [Select]
$stuff = preg_match('~\[1\]*\[/1\]~',$pagetext);

when I put print_r($stuff); it gave me a 0, it should have said

$_stuff[0] = Section 1
$_stuff[1] = Section 2
$_stuff[2] = Section 3

Any ideas?

Try this out, not sure if that's what you wanted though.

$input = <<<html
[1]Section 1[/1]
Blah Blah Blah
[1]Section 2[/1]
Blah Blah Blah
[1]Section 3[/1]
html;

preg_match_all("#\[1\](.+)\[/1\](.*[^\[1\]]*)#i", $input, $matches);
$sections = array();
for($i = 0; $i < count($matches[1]); $i++){
$sections[] = array("title" => $matches[1][$i], "content" => trim($matches[2][$i]));
}

echo "<pre>", print_r($sections), "</pre>";

That looks good, but what variable is the titles stored in? I only need the titles, not the content.

Okay, in that case then, this should work:

$input = <<<html
[1]Section 1[/1]
Blah Blah Blah
[1]Section 2[/1]
Blah Blah Blah
[1]Section 3[/1]
html;

preg_match_all("#\[1\](.+)\[/1\]#i", $input, $matches);
$sections = array();
for($i = 0; $i < count($matches[1]); $i++){
$sections[] = $matches[1][$i];
}

echo "<pre>", print_r($sections), "</pre>";
