hi, all i read some articles on the website but didn't find what i wanted because i'm a bit novice in ereg.

I spend 24h to find a solution and don't find it yet ;(

i have this :

$myvar="a..........b..........this0textherethis1..........c..........d..........e..........this0anothertextherethis1..........f..........this0athingthis1";

and 1) i want to delete all that is between  this0---------this1  with a preg_replace but that replace all

after 2) i can clean $myvar just with a str_replace on  this0 and this1

to have

 $myvar="a..........b....................c..........d..........e....................f..........";

I test with preg_match_all but i don't want a tab in output i just want myvar

Is it possible to delete  all stuff that start with this0 and end with this1 ?

 Can somebody write all the regex expression for me (i'm novice)

thanks a lot. 

In the 'Construction Advice' forum, there is a sticky note (http://regexadvice.com/forums/thread/41315.aspx) that says what information we need to properly answer questions. One of the items listed there is to get real examples of the text to be manipulated.

In this case, I could tell you to use the pattern

this0[a-z]+?this1

with a blank replacement string, but I doubt if this will mean much, especially as you say that you are a beginner. There are many other things that can make this fail such as the case of the characters, what appears just before 'this0' and after 'this1', if the test between these two markers is really only alphabetic characters and so on.

Thanks a lot, i finally learn all the little property of easy regex and found a little solution with separator #[this0]....

By and thanks for response. 

I'm not sure if you have posted exactly the pattern you are using (it doesn't make much sense compared to the original example you provided.

Regardless, your use of the square brackets is a bit worrying as they define a character class which means that "[this0]" will match a SINGLE character that is one of the number 0, 's', 'i', 't' or 'h'. Given the original example this would be wrong of you  were really trying to match the 4 characters 'THIS' in that order.
