php - Break query data into several files -

i want table database , break output data files (50 entries in each file): list01.txt, list02.txt... somehow got stacked @ question how break data more effectively.

if ( $result = $mysqli->query($query) ) {      icount = 0;     while ( $row = mysqli_fetch_array($result) ) {         if ( icount % 50 == 0 ) {             $snum = int( icount / 50 );             $filename = 'scripts/spisok'.$snum.'.txt';             $handle = fopen( $filename, 'w' );         }         fwrite( $filename, $row['uname'].';'.$row['email'].'<br />' );         icount++;     }      echo 'ok';     $result->free();  } 

can break $result 50-entry arrays first , write them all? sorry, im novice php

you can use array_chunk

<?php   if ( $result = $mysqli->query( $query ) ) {     $data = array();     while( $row = mysqli_fetch_array( $result ) ) {       $data[] = $row['uname'].';'.$row['email'];     }     $result->free();      // divide array desired number of split lists     $chunks = array_chunk( $data, 50 );     // loop through chunks     foreach( $chunks $index => $chunk ) {       $file   = 'scripts/spisok'.( $index + 1 ).'.txt';       $chunk  = implode( "<br />", $chunk );       file_put_contents( $file, $chunk );       // or       /*       $handle = fopen( $file, 'w' );       fwrite( $handle, $chunk );       fclose( $handle );       */     }     unset( $data, $chunks );   } ?>
