preg help

Hi, I need to match stuff between curly brackets.

So basically I'm trying this:

$string = "{PAGE_TITLE} - {PAGE_NAME}";
preg_match( '/{PAGE_(.*)}/', $string, $array );

print_r($array);

Which leaves me with this:

Array
(
    [0] => {PAGE_TITLE} - {PAGE_NAME}
    [1] => TITLE} - {PAGE_NAME
)

Which is obviously not the result I want.

What I want is this:

Array
(
    [0] => {PAGE_TITLE}
    [1] => {PAGE_NAME}
)

Any help is appreciated,

Chris

Just te make it more clear.

You want to match everything between brackets, or do you only want to match stuff between brackets starting with PAGE_

I only want to match stuff between brackets starting with PAGE_.

Ok ill start puzzeling

-edit:  wel this should work, but since you didn't specify what other caracters are allowed i used .* if you want to use a limited range of characters let me know.

/({PAGE_(.*)})/

Hmm i changed it a bit,

'/({PAGE_.*?})/' 

but its not getting the second match yet. Working on it

I think we should use preg_match_all to match more instances of a subpattern:

$string = "lalala {PAGE_TITLE} - {PAGE_NAME} lalalsa";
        preg_match_all( '/({PAGE_.*?})/', $string , $array);

        print_r($array);

Note though that [0] prints out the shows all the substrings that matched the pattern.

OK i have another solution that meet your needs more, but it's maybe not the best way of doing it.

$stringy = "lalala {PAGE_TITLE} - {PAGE_NAME} lalalsa";
            $array_stringy = explode(" ", $stringy); // put string in an array delimiter is the 'space'
            //print_r ($array_stringy);
            $fl_array = preg_grep("/({PAGE_.*?})/", $array_stringy); // select only the pieces from the array that match your pattern
            $clean_array = array_values($fl_array); // resseting keys of array
            print_r ($fl_array); // unsorted looking array
            echo '<br>'; //break for some order
            print_r($clean_array); //clean aray with new keys starting at 0

If anyone knows a better way please let me know. I have a feeling this is inefficient 

$string = "{PAGE_TITLE} - {PAGE_NAME}";
preg_match_all( '~{[^}]+}~', $string, $array);
print_r($array);

Array
(
    [0] => Array
        (
            [0] => {PAGE_TITLE}
            [1] => {PAGE_NAME}
        )

)

oh that's very smart!

Just for my knowledge, if i split it up in parts is this the correct interpretation?

1)  '~{  }~'  // enclose the pattern in { and }

2)  [^}]+  // does this mean it may not contain }  , and that the inside must at least appear 1 or more time ?

~{[^}]+}~


~     starting delimiter
{     match a literal open curly brace
[^}]  negative character class meaning match anything that is not a closing curly brace
+     match one or more of the previous thing, so match one or more of anything that is not a closing curly brace.
}     match a literal closing curly brace
~     ending delimiter 

Thanks Crayon, ;-) i am getting a little better everyday at this regexp.

$string = "{PAGE_TITLE} - {PAGE_NAME}";
preg_match_all( '~{[^}]+}~', $string, $array);
print_r($array);

 

Array
(
    [0] => Array
        (
            [0] => {PAGE_TITLE}
            [1] => {PAGE_NAME}
        )

)

Thanks! And everyone else!
