PHP - It Is Possible To Use Serialize/unserialize To Do This?
Similar Tutorialsi tried to serialize an array in php but im not sure if i had the right syntax $field[0] = "Student Name"; $field[1] = "fail"; $field_ser = serialize($field); $field_unser = unserialize($field_ser); i think i didnt do it right Code: [Select] $order = array(0,1,2); echo serialize($order); Shows: Code: [Select] a:3:{i:0;i:0;i:1;i:1;i:2;i:2;} which is fine, because I can use unserialized. But I need to let me users switch between 0,1,2 to be in what ever order they want it to!, how would I go about saving the data ? Hello, I'm looking for a better serialize() function. the php one has a fault of counting the slashes, before stripping them out, making the deserialize() fail, because the actual string count, is different from the string count as referenced... does anyone have one already? I want to store an array in a mysql table. all of the values in the array are numbers. Should I serialize or implode? What's the difference? Thanks! Hello! guys this is my code <?php include("header.php"); include("conn.php"); ?> <html> <head> </head> <body> <table border="1" cellpadding="0" cellspacing="0" align="center"> <tr> <td>Please Enter the Amount</td> <td valign="top" align="left" width="200"> <form action="next.php" method="post"> <input name="amount" value="1" size="7"> </td> <tr> <td>From:</td> <td valign="top" align="left" width="200"> <?php $real= array ( 'USD'=>1, 'PAK'=>1.6323, 'GBP'=>1.02544 ); $abc= mysql_real_escape_string( serialize($real) ); //$ddsr=unserialize($abc); //$abc= implode(",",$real); //echo $abc; $from= array('Dollars','Rupees','Pounds'); $length = count($from); //$dbs=implode(",",$from); $dql = "INSERT INTO countrytype (`ID`,`fromcountry`,`tocountry`) VALUES ('','".$abc."','".$abc."')"; mysql_query($dql) or die(mysql_error()); $to= array('Dollars','Rupees','Pounds'); $to=str_replace("","",$to); ?> <input type="hidden" name="h1" value="<?php echo $length;?>"> <select> <?PHP $dgd= "SELECT * FROM countrytype GROUP BY ID"; $aws= mysql_query($dgd) or die(mysql_error()); while($row=mysql_fetch_array($aws)) { $des=stripslashes($row['fromcountry']); $dsw=unserialize($des); //$des=explode("",$row['fromcountry']); //var_dump($dsw); //echo "<td>".$row['ID']."<td>"; //echo "<td>".$dsw."<td>"; $k=1; foreach($dsw as $key=>$value) { echo "<option name='ad[]' value='$value'>$value</option>"; //print_r(array_keys($des)); $k++; } } //$sss=explode("",$row['fromcountry']); //echo $sss; ?> </select> <select> <?php $i=0; $k=1; foreach($from as $abd => $value) { echo "<option name='ar[]' value='$value' >$value</option>"; $k++; } ?></td></tr></select> <td>To: </td><td><select> <?php foreach($to as $abd => $value) { $i++; echo "<option id='i' >$value</option>"; } ?> </select> <input type="submit" name="sub" value="Convert!"/> </form> </td> </tr> </tr> </table> </body> </html> serilization works but when i fetch it from database and unserialize it nothing works Need a bit of help with some php and a few kind members helped me in the past. My code is: $query = "SELECT names FROM table WHERE type='$type'"; $result = mysql_query($query) or die(mysql_error()); while($row = mysql_fetch_array($result)) { foreach(unserialize($row['names']) as $key => $value){ echo $value . '<br />'; } } Basically, a field on my table is called names. The information in this field is serialized (so many names are together in a single field, for a single row). I want to be able to search the whole table (where type='$type' - so many rows) for all names and then show unique names only. My code above unserializes the names from each field and then lists them, but doesn't deal with any duplicates (which I need removing). I have looked at functions like "unique_array()", and have tried using it in different places but it isn't doing the job. Any help appreciated. I took an object, and saved it into a database serialized. Code: [Select] $object_here = serialize($theobject); Then later on, I go and I get that data from a database, and try to unserialize it.. Code: [Select] $objecthere = unserialize($row->theobject) And it throws the following error...any advice? Quote Warning: unserialize() [function.unserialize]: Node no longer exists in /path/to/file on line 20 Hey I got this script which is trying to unserialize but i get this error and have no idea what it means so i equally have no idea how to fix the problem. This is what it says: Quote Notice: unserialize() Error at offset 0 of 4 bytes This is the line which causes the error: Code: [Select] <?php $contents = unserialize(file_get_contents($this->msgsFile)); ?> Does any one know what the error means? And what i need to look for to fix it. my user pm table has a touserarray field which is a serialized array that looks like this: a:1:{s:2:"cc";a:1:{i:15773;s:14:"testusername";}} i know I can unserialize it with the unserialize() function. But I need to extract the value corresponding to 'i' field and the 's' field that has the username. So from the above array, i need to retrieve the value '15773' and 'testusername'. Can someone tell me how? I have an array from the database like so Array (2) ( | ['0'] => Array (4) | ( | | ['f_fid'] = String(1) "1" | | ['0'] = String(1) "1" | | ['f_names'] = String(99) "a:4:{i:0;s:18:"register_user_name";i:1;s:5:"r_u_n";i:2;s:10:"user_alias";i:3;s:12:"nickusername";} " | | ['1'] = String(99) "a:4:{i:0;s:18:"register_user_name";i:1;s:5:"r_u_n";i:2;s:10:"user_alias";i:3;s:12:"nickusername";} " | ) | ['1'] => Array (4) | ( | | ['f_fid'] = String(1) "2" | | ['0'] = String(1) "2" | | ['f_names'] = String(104) "a:4:{i:0;s:18:"register_password";i:1;s:5:"r_pass_word";i:2;s:10:"user_pass";i:3;s:12:"reg-pass-word";} " | | ['1'] = String(104) "a:4:{i:0;s:18:"register_password";i:1;s:5:"r_pass_word";i:2;s:10:"user_pass";i:3;s:12:"reg-pass-word";} " | ) ) So i use a foreach loop to turn the serialized value into an array foreach($fields as $key => $val) { $fields[$key]['f_names'] = unserialize($val['f_names']); } But for some reason the last f_names is false Array (2) ( | ['0'] => Array (4) | ( | | ['f_fid'] = String(1) "1" | | ['0'] = String(1) "1" | | ['f_names'] => Array (4) | | ( | | | ['0'] = String(18) "register_user_name" | | | ['1'] = String(5) "r_u_n" | | | ['2'] = String(10) "user_alias" | | | ['3'] = String(12) "nickusername" | | ) | | ['1'] = String(99) "a:4:{i:0;s:18:"register_user_name";i:1;s:5:"r_u_n";i:2;s:10:"user_alias";i:3;s:12:"nickusername";} " | ) | ['1'] => Array (4) | ( | | ['f_fid'] = String(1) "2" | | ['0'] = String(1) "2" | | ['f_names'] = Boolean(0) FALSE | | ['1'] = String(104) "a:4:{i:0;s:18:"register_password";i:1;s:5:"r_pass_word";i:2;s:10:"user_pass";i:3;s:12:"reg-pass-word";} " | ) ) Anyone have any idea why? Thanks Hi everyone, Im trying to serialize the values of checked checkboxes, save them to a database, then on another page retrieve the value from the database, unserialize it, and then write each checkbox value to the database individually. Using the following test code I'm able to serialize the checkbox values, and then unserialize them and echo them out fine, however im unsure how to separate them and save them individually into the database. $string = implode($_POST['checkbox']); $test = serialize($string); $test2 = unserialize($test); echo $test2; <?php $i = 0; ?> <?php while ($row = mysql_fetch_assoc($query)) { ?> <tr> <td><input type="checkbox" name="<?php echo "checkbox[$i]"; ?>" value="<?php echo $row['test']; ?>" /></td> </tr> <?php $i++; } ?> Any ideas? Thanks I am trying to unserialize this string: a:3:{s:3:\"zip\";s:5:\"55068\";s:4:\"city\";s:9:\"Rosemount\";s:5:\"state\";s:2:\"MN\";} but I unserialize is returning false. Why is it doing that? $info = unserialize($_COOKIE['zipcode']); var_dump($info); Hi, I'm new to PHP and wondered if anyone could help... I am consuming an asmx webservice using PHP code. (Later to make a widget for wordpress). I can receive all the data, but it is in one very big xml file. I want to be able to convert this data, so I can make it more readable. Could really do with help as I don't have a clue how to convert it. ANy ideas? Is this a mistake in the documentation? I am running PHP7.4 and get warning: unserialize() expects parameter 2 to be array, bool given. QuoteEither an array of class names which should be accepted, false to accept no classes, or true to accept all classes. If this option is defined and unserialize() encounters an object of a class that isn't to be accepted, then the object will be instantiated as __PHP_Incomplete_Class instead. Omitting this option is the same as defining it as true: PHP will attempt to instantiate objects of any class.
Debian 5 PHP 5.2.6-1 This script works: <? $output = shell_exec('ls -lart'); echo "<pre>$output</pre>"; ?> This script doesn't work: <? $vars=unserialize(file_get_contents("file.txt")); $output = shell_exec('ls -lart'); echo "<pre>$output</pre>"; ?> I get error: Quote Warning: shell_exec(): Unable to execute 'ls -lart' or Warning: system(): Unable to fork [ls -lart] If file.txt has size 500k, the script works without errors.

How do I fix it? Hello, I have a call tu function unserialize() in a script that receives a string and has to return an array. In my localhost it works properly but in the server it returns a 1 dimension array with empty value. I'm testing with the string a:1:{s:1:"0";s:8:"value_eq";} The php.ini configuration for magic_quotes is (in both, server and localhost): magic_quotes_gpc Off magic_quotes_runtime Off Other configurations is difficult to compare, as php info is long and very different in local and server. Any ideas where the problem might be? Thank you |
