there is a test file of the form

(0:00) text1 text2 (0:30) text text text text text ..................

you need to get an array of the form key - this is the value in brackets, and the value is a test.

 array("(0:00)"=>"text1 text2","(0:30)"=>"text text text text text")

I write the following:

  $key = array(); $val = array(); $out = array(); $file = file('1.txt'); foreach($file as $line) { $line = trim($line); if (preg_match("/(\d{0,2}:\d\d)/",$line,$match)){ $key[]=$match; }else{ $val[]=$match; } $out=array_merge($key,$val); } echo '<pre>'; print_r($out);

tell me how to fix?

If you still extract the entire contents of the file using the file() function into RAM, can you then do without an array? Extract the contents of the file into a single line using the file_get_contents() function. It will be much more convenient to get all entries, for example, using preg_match_all() , and then, based on the response received (below is $results ), generate the $out array you need

 <?php $out = array(); $file = file_get_contents('1.txt'); preg_match_all("/(\(\d{0,2}:\d{2}\))([^\(]+)/", $file, $results); foreach($results[1] as $key => $value) { $out[$results[1][$key]] = $results[2][$key]; } echo '<pre>'; print_r($out); 
     $key = ''; $val = array(); $out = array(); $file = file('1.txt'); foreach($file as $line) { $line = trim($line); if (preg_match("/(\d{0,2}:\d\d)/",$line,$match)){ $key = $match; }else{ $val[$key][] = $match; } } foreach($val as $k=>$v) $val[$k] = implode(' ',$v); echo '<pre>'; print_r($val);
