范例

Example #1 Get the entry contents with fread() and store it

  <?php
$contents  =  '' ;
 $z  = new  ZipArchive ();
if ( $z -> open ( 'test.zip' )) {
     $fp  =  $z -> getStream ( 'test' );
    if(! $fp ) exit( "failed\n" );

    while (! feof ( $fp )) {
         $contents  .=  fread ( $fp ,  2 );
    }

     fclose ( $fp );
     file_put_contents ( 't' , $contents );
    echo  "done.\n" ;
}
 ?>

Example #2 Same as the previous example but with fopen() and the zip stream wrapper

  <?php
$contents  =  '' ;
 $fp  =  fopen ( 'zip://'  .  dirname ( __FILE__ ) .  '/test.zip#test' ,  'r' );
if (! $fp ) {
    exit( "cannot open\n" );
}
while (! feof ( $fp )) {
     $contents  .=  fread ( $fp ,  2 );
}
echo  " $contents \n" ;
 fclose ( $fp );
echo  "done.\n" ;
 ?>

Example #3 Stream wrapper and image, can be used with the xml function as well

  <?php
$im  =  imagecreatefromgif ( 'zip://'  .  dirname ( __FILE__ ) .  '/test_im.zip#pear_item.gif' );
 imagepng ( $im ,  'a.png' );
 ?>

I experienced problems using fread to read the content of the zip when the file was PDF. Using stream_get_contents instead solved the problem.
