    This preg_replace how do I use it with arrays ?

    Hi,

    I have some data to find and replace from a string.

    The find and replace data is in a mysql table
    so I can easily extract it and build 2 arrays,
    or build an associated array

    ( I am not sure which, so I did both)

    PHP Code:
    $sql "SELECT word,replacement FROM theos order by word";
        
    $result mysql_query($sql) or die("Could NOT select words"mysql_error() );

        
    $words = array();
        
    $replacements= array();
        
    $words_reps = array();
        
    $new_words = array();
        
    $new_words_reps = array();
        
        while (
    $row mysql_fetch_assoc($result)) {
            
    extract($row);
            
    $words[] = $word;
            
    $replacements[] = $replacement.' ';
            
    $words_reps[$word] = $replacement ;
            } 
    The string to do the find and replace on is a sentence like this:

    $input_data =
    there is something about being the parent of a very small child a child who has not yet begun to form words that has exerted a subtle pressure on the way i think about language in general my investment in words is heavy and more or less literal in the sense that they are the means by which i make at least in theory my living since my son was born six months ago the first way in which my relationship with words has changed is this i haven't been able to get nearly enough of the words down on paper

    Now I could make that array:
    PHP Code:
    $input_data_arr explode(' '$input_data); 
    But I don't know if I need to.

    My FIND array $words
    looks like this:


    2
    a
    about
    access to
    across the
    advert
    advice
    ago
    agreement

    My REPLACE array $replacements
    looks like this:

    {2|two|only two}
    {a|some|a very|a definite|a specific|a particluar}
    {about|regarding|concerning|with regards to|in relation to|related to|pertaining to|on the subject of|when it comes to|in regards to|in regard to|with regard to|on the subject off|as regards to}
    {access to|usage of|use of|the means to access}
    {across the|around the|all over the|over the|through the|round the|all around the}
    {advert|advertisement|ad|offer|promotion|special offer|promo|campaign|deal|special promotion|special deal}
    {advice|guidance|suggestions|tips|assistance|information|help and advice|recommendations|help|aid|instruction|counsel}
    {ago|back|in the past|earlier|previously|previous|prior}
    {agreement|arrangement|contract|deal}


    AND THE associated array:

    ( Using this to list it:

    PHP Code:
    foreach($words_reps as $x=>$x_value) {
            echo 
    $x "-->" $x_value;
            echo 
    "<br>";
            } 
    2-->{2|two|only two}
    a-->{a|some|a very|a definite|a specific|a particluar}
    about-->{about|regarding|concerning|with regards to|in relation to|related to|pertaining to|on the subject of|when it comes to|in regards to|in regard to|with regard to|on the subject off|as regards to}
    access to-->{access to|usage of|use of|the means to access}
    across the-->{across the|around the|all over the|over the|through the|round the|all around the}
    advert-->{advert|advertisement|ad|offer|promotion|special offer|promo|campaign|deal|special promotion|special deal}
    advice-->{advice|guidance|suggestions|tips|assistance|information|help and advice|recommendations|help|aid|instruction|counsel}
    ago-->{ago|back|in the past|earlier|previously|previous|prior}
    agreement-->{agreement|arrangement|contract|deal}


    In order to use preg_replace(),
    I wanted to add some reg_exp so that when I search for

    "a" it does NOT get found in "about" but only as "a"

    ( maybe I should use a \b for word boundary ? )

    Anyway, I changed the FIND array to be:
    $new_words

    "/^2$/"
    "/^a$/"
    "/^about$/"
    "/^access to$/"
    "/^across the$/"
    "/^advert$/"
    "/^advice$/"
    "/^ago$/"
    "/^agreement$/"

    I also change the associated array:
    $new_words_reps:

    "/^2$/"-->{2|two|only two}
    "/^a$/"-->{a|some|a very|a definite|a specific|a particluar}
    "/^about$/"-->{about|regarding|concerning|with regards to|in relation to|related to|pertaining to|on the subject of|when it comes to|in regards to|in regard to|with regard to|on the subject off|as regards to}
    "/^access to$/"-->{access to|usage of|use of|the means to access}
    "/^across the$/"-->{across the|around the|all over the|over the|through the|round the|all around the}
    "/^advert$/"-->{advert|advertisement|ad|offer|promotion|special offer|promo|campaign|deal|special promotion|special deal}
    "/^advice$/"-->{advice|guidance|suggestions|tips|assistance|information|help and advice|recommendations|help|aid|instruction|counsel}
    "/^ago$/"-->{ago|back|in the past|earlier|previously|previous|prior}
    "/^agreement$/"-->{agreement|arrangement|contract|deal}


    OK !

    So now I want to use the preg_replace()

    BUT my question is - do I need to use the associated array
    or do I use the two FIND and REPLACE arrays

    Since these 2 arrays were generated from the same table, they have the same
    natural keys - does that keep them in step when replacing ?

    If I use the two arrays, I guess it should like this ...

    PHP Code:
    $new_data preg_replace($new_words,$replacements,$input_data); 

    If is the assocated array, I don't know how to write that !!

    Am I correct in thinking that the input can be a string ?
    Or does that need to be an array as well ?


    Sorry,
    A lot of questions .. but I am not sure how to do this !!

    Thanks for any help !
