Serialized data list to foreach

How can I list the serialized data retrieved from the database. My code is failing.



PHP 5.6



My data



a:3:{i:0;a:4:{s:2:"no";i:2;s:4:"name";s:23:"file-417-1546062916.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}i:1;a:4:{s:2:"no";i:1;s:4:"name";s:23:"file-417-1546063067.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}i:2;a:4:{s:2:"no";i:3;s:4:"name";s:23:"file-417-1546063154.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}}


My code



$fileStr = $getMeta('post_files', $pID);
$list = ($fileStr) ? unserialize($fileStr) : '';
foreach ($list as $k => $v) {
echo $k.' - '.$v;

You have a multidimensional array which means you need two foreach nested.



$str = 'a:3:{i:0;a:4:{s:2:"no";i:2;s:4:"name";s:23:"file-417-1546062916.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}i:1;a:4:{s:2:"no";i:1;s:4:"name";s:23:"file-417-1546063067.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}i:2;a:4:{s:2:"no";i:3;s:4:"name";s:23:"file-417-1546063154.zip";s:4:"type";s:28:"application/x-zip-compressed";s:4:"size";i:31835501;}}';
$list = unserialize($str);
if(!empty($list)){ // check if the array/string is empty
foreach ($list as $k => $v) {
echo $k . "n";
foreach($v as $k2 => $val){
echo $k2.' - '.$val . "n";
}
echo "nn";
}
}


Output:

To see what the array looks like you can use print_r/var_dump or var_export.

They will show how many levels deep your array is, if it's a unknown number of levels then you can use array_walk_recursive to walk the array.

  • @Murat :-) . I see that you use a ternary to see if you want to unserialize or not. Unserialize will fail silently and not create any problems. Foreach however will not fail silently. I would remove the ternary and add a if empty as this: 3v4l.org/p2hUn that way if the string is empty no problems.
