php - concatenate

[idorjee]

hi,
how can i concatenate the part of the first and the next line, leaving the 'DE' in the beginning if i have the following in a text file?

DE Chloride intracellular channel protein 5 (Chlorine channel protein
DE p64).

i want it like this:
Chloride intracellular channel protein 5 (Chlorine channel protein p64).

the following doesn't work.

if (preg_match("/DE\s+(.+)/", $buffer, $desc)) { $description .= $desc[1]; }
 

thank you.

idorjee,
preg_match() just returns the number of times a specified pattern is matched. Take a look at the str_replace () or the substr_replace() functions. Reading the line in as a string and then using one of those you could replace "DE" with "" to get your desired result.

preg_replace() is faster ;)

markusn00b...very good point!

Also, because the DE is on a new line, you might want to include the \n line carriage.

hi guys,
thanks for your suggestions, but i still couldn't get around with it. following is a part of the script that i'm working on

$text_info = curl_init("http://domain.com/$id.txt");
$buffer = curl_exec($text_info);
echo preg_replace('/DE\s+(.+)/', ' ', $buffer);
 

i was wondering why do i need to replace my pattern with a space, as that's the one i need. and also the are in the $buffer, lines like:

DE Potassium voltage-gated channel subfamily A member 3 (Voltage-gated
DE potassium channel subunit Kv1.3) (HPCN3) (HGK5) (HuKIII) (HLK3).
RP NUCLEOTIDE SEQUENCE [GENOMIC DNA].

the last line also has the 'DE\s+(.+)' pattern which i am not interested in.

is there any way i could save the replaced part? how could i do this. please help.
thanks a lot.
