regular exp.

[yp56]

hello,

I've got a variable wich contains something like this :

$myvar = "textextext\FIELD1\textextexte\FIELD2\textextext\FIELD3\textext....."

And I want to get all field in an array. so I try to use ereg() like this :

ereg("^([^\\\\]*(\\\\[A-Z0-9]*\\\\)[^\\\\]*)$&quot, myvar, myarray);

And it doesn't work :c(
Can someone help me, please ? :c)
thaks a lot....

How 'bout

$myarray = preg_split ('/\\\\FIELD\d+\\\\/', $myvar);

Well, I'm the kind of person that only uses regex when there is no other solution. Call me a coward ;-).

If you do a simple

$my_array = explode('/',$myvar)

, you will receive an array, consisting of ("textextext", "FIELD1", "textextext", "FIELD2&quot etc... So, if this is the pattern, then that means even-numbered indexes have your data, while the odd-numbered ones have your field names. (

http://php.net/explode)

Thus $my_array[0] is "textextext"

and $my_array[1] is "FIELD1"

So, if you get the length of that array with $arr_len = sizeof($my_array), then you can loop through the array, assigning field names and data:

for($i = 0; $i < $arr_len; $i+=2) //iterate by 2
{
  echo $my_array[($i + 1)] . &quot; = $my_array[$i]<br>\n&quot;;
}

This should output something like:

FIELD1 = textextext
FIELD2 = textextext
etc... -------------------------------------------

yp56,

rycamor's method also has the advantage over mine that you can preserve those fieldnames if you ever needed to. ______________________________________________________________________

yes, I use :
foreach(explode("\\", $var) as $k=>$v){
if ($k % 2 == 1) {
...$v...
}
}

your mehod was very well but it gives me ('textextextex1', 'textextextex2', 'textextextex3', ...)
and I wanted ('FIELD1', 'FIELD2', ...) :cD

My apologies, I must have misread your post. I thought the "FIELDn" tags were your field delimiters. ______________________________________________________________________
