php - Finding and combining two strings from an array -

i have text file contains following lines, have read array called $pirep.

06:36  block block duratio n: 07:37  06:36  final fuel: 1044 lbls 

i have written code find "block block duration" , record time follows database. problem code cannot find string because text file broken down 1kb chunks, , happened fall right in middle of search string.

i understand how use str_replace(php_eol, '') join 2 strings, , great if data written @ same place every time, isn't.

is there way recognize time pattern precedes every line , combine lines until finds next occurrence of pattern, end result looks like:

06:36  block block duration: 07:37 06:36  final fuel: 1044 lbls 

this second question, , i'm hoping not on anyone's nerves this. thanks!

edit

here code using parse text file;

//read temp file array $pirep=file("temp.txt"); $num=count($pirep);  //assign known variables $pnum=explode(":",$pirep[2]); $dca=$pnum[1]; $fltnum=explode(":",$pirep[1]); $flt=$fltnum[1]; $date=$pirep[0]; //$dep=$pirep[5]; //$dest=$pirep[6];  //determine if mainenance division flight, set variable accordingly for($i=0;$i<$num;$i++) {     $line=$pirep[$i];     if(strpos($line,"maint")!==false) {         $maint="yes"; }  }  //cycle through pirep array , find departure , destination airports for($i=0;$i<$num;$i++) {     $line=$pirep[$i];     if(strpos($line,"departing airport")!==false) {         $dep=$pirep[$i]; } } for($i=0;$i<$num;$i++) {     $line=$pirep[$i];     if(strpos($line,"destination airport")!==false) {         $dest=$pirep[$i]; } }  //cycle through pirep , find block block duration for($i=0;$i<$num;$i++) {     $line=$pirep[$i];     if(strpos($line,"block block duration")!== false) {         $duration=ltrim(strstr($line,"duration"),"duration:");          $flttime=explode(":",$duration);         $minutes=($flttime[0]*60)+$flttime[1]; } }  //cycle through pirep , find comments if exist for($i=0;$i<$num;$i++) {     $line=$pirep[$i];     if(strpos($line,"comments")!== false) {         $raw_comments=ltrim(strstr($line,"comments "),"comments");         $comments=addslashes($raw_comments); } }  //connect dca , find pilot include('connect_db.php'); $stmt="select * newpilots dca=$dca limit 1"; $result=mysql_query($stmt); if(!$result) {echo"<br> query error<br>"; } if(mysql_num_rows($result)==0) {echo "<br>pilot $dca not found<br>"; } $count=mysql_num_rows($result);     $lastname=mysql_result($result,0,'lastname');     $firstname=mysql_result($result,0,'firstname');     $current_minutes=mysql_result($result,0,'minutes');     $email=mysql_result($result,0,'email');     $name=$firstname."
