Anyway, I would do it like this: $fp=fopen("file.txt","r"); while(!feof($fp)) { $line=fgets($fp,256); list($key,$value) = split("[[:space:]]+",$line); $array[$key] = $value; } fclose($fp); /* Loop through your array like this */ while(list($key,$value) = each($array)) { echo "array[$key] = $value\n"; } This script would give you: array[name1@someaddress.com] = realuser array[jmorris@someaddress.com] = realuser2 array[ajacinto@anotheraddress.net] = ajacinto Obviously if you wanted to switch the key and the value, you could do that easily in the script. I didn`t use the file() function because I don`t see any reason to load the entire file into memory and have multipe complete copies of the information eating up your memory. This version goes line by line and doesn`t use very much memory in case your file might be large. And, if the separator between the address and the user id is a known character or string, use the explode() function instead of the split() function. I wrote it so any amount of whitespace could be between the two strings, but if you can get away with using explode() instead you should since it is much more efficient to avoid regular expressions. | |||||
