PHP - Memory Limit Error

I have a wordpress site that has this error in my error logs and seems to be causing the site to load very slow:
PHP Fatal error:  Allowed memory size of 67108864 bytes exhausted (tried to allocate 64 bytes) in /home/name/public_html/wp-includes/meta.php on line 339

this is line 339:
Code: [Select]
$cache[$mpid][$mkey] = array();
a couple line above and below:
Code: [Select]
if ( !empty($meta_list) ) {
foreach ( $meta_list as $metarow) {
$mpid = intval($metarow[$column]);
$mkey = $metarow['meta_key'];
$mval = $metarow['meta_value'];

// Force subkeys to be array type:
if ( !isset($cache[$mpid]) || !is_array($cache[$mpid]) )
$cache[$mpid] = array();
if ( !isset($cache[$mpid][$mkey]) || !is_array($cache[$mpid][$mkey]) )
$cache[$mpid][$mkey] = array();

// Add a value to the current pid/key:
$cache[$mpid][$mkey][] = $mval;
}
}
Can some please help this is causing major issues.

Hi.

I tried to add some more if statements to check for validation and I'm now getting this error.  The "on line ###" changes depending how many fields are FALSE.


Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 35 bytes) in /home/content/f/u/s/fusionfashion/html/registration.php on line 133

I think it has to do with the php.ini file.  So I added the memory_limit in the php.ini file.

Code: [Select]
register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = "EGPCS"
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
memory_limit = 128M
post_max_size = 128M
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset="

[Zend]
zend_extension=/usr/local/zo/ZendExtensionManager.so
zend_extension=/usr/local/zo/4_3/ZendOptimizer.so

But I'm still getting the error.  How to I check my php version and this value within a browser? 
<?php phpinfo() ?>  Found this. 

Its showing 64M in LOCAL and MASTER.  But I just updated the local?

I'm getting a fatal memory error and have been unable to figure out what is causing it. To make it worse, the allowed memory size does not appear to be related in any way to the memory_limit value. Here's the information:

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 128 bytes) in template.php on line 164
Excerpt from template.php (line 164 is where $max is assigned):
...
else if(isDateType($type) || isTimestampType($type) || isDatetimeType($type))
{
$min = htmlentities($countpost['constraints'][$tablename][$fieldname]['min'], ENT_QUOTES);
$max = htmlentities($countpost['constraints'][$tablename][$fieldname]['max'], ENT_QUOTES);
echo "\t\tFrom: <input name=\"constraints[$tablename][$fieldname][min]\""
." type=text value=\"$min\" onclickXSSCleaned=\"toggleCalendar(this)\" readonly>\n";
echo "\t\tTo: <input name=\"constraints[$tablename][$fieldname][max]\""
." type=text value=\"$max\" onclickXSSCleaned=\"toggleCalendar(this)\" readonly>\n";
}
...

These two lines were included at the top of the script and printed "Base Memory Usage: 473172 Memory Limit: -1":
echo "Base Memory Usage: ". memory_get_usage() ."\n";
echo "Memory Limit: ". ini_get('memory_limit') ."\n";
I also get the same error in a slightly different location:
Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 1 bytes) in template.php on line 153
Excerpt from template.php (line 153 is the simple variable assignment of an empty string):
...
if(!isset($countpost['constraints'][$tablename][$fieldname]['value']))
$countpost['constraints'][$tablename][$fieldname]['value'] = "";
...

If I refresh the page repeatedly, the error will predictably occur at the same place. Once I change any code (even slightly), the location of the error will change to a new location, sometimes into an included file. The size of "tried to allocate X bytes" also changes. The only constant in this whole mess is the allowed memory size (which is ALWAYS 262144, no matter what the actual memory limit is).

I had previously set memory_limit to -1 in the php.ini file, which seems to have no effect on the error. I am not using a .htaccess file. Changing the memory_limit doesn't change the "allowed memory size" whether it's set to 16M, 64M or whatever.

I've restarted apache after each change in php.ini.

I have memory_get_usage in the code several times to watch the memory. There are small changes, and a change of about 300k when I first load another file. The max gets up to 1048576 bytes (memory_get_peak_usage). 1 Mb does not seem very large to me and is much smaller than the memory_limit.

Also, today I wrote a short php script to just use up memory.  This was just to test php and see if my installation is messed up.  It worked just fine and I got up to 128Mb used without encountering the error above.  So it's something in my code.

This is using php 5.3.2, apache2 2.2.14, on Ubuntu 10.04. Any insights would be greatly appreciated.

Rage.

The whole error message reads:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 16 bytes)

Dunno bout you but that doesn't make sense to me!

Anywho I am constantly getting this error when any PHP variables are stored or anything. I'm guessing thats the case coz its saying the error is on line 6 which is:

$card = rand(1,52);

I tried a search on google but just got confused, is there a simple explanation why this is happening? thanks alot guys

Hi ,

 As you may all have experienced this problem is there way we can non-healthy exit of script ..due to memory problem........???

I got to know..we avoid this......by properly managing our php memory by unset function. remove unusable variables and objects from memory......

Is there any way we can check each time inside the script -to check memory is available  or sleep for some time and check again.......to proceed without exit........

Is there a way to catch this fatal error and take necessary steps to avoid exit........

Thanks,
redfort  :confused:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4864 bytes) in /home/a5418385/public_html/scripts/status.php on line 2 What does this mean?

I handle MySQL errors like this:

function handle_error($err) {
     throw new Exception($err);
}
try {     
     $con = mysql_connect("", "", "") or handle_error("mysql_connect failed! ");
     mysql_select_db("") or handle_error("mysql_select_db failed! ");
     $sql = "SELECT blah blah blah ...";
     $result = mysql_query($sql, $con) or handle_error("mysql_query failed! ");                   
}
catch(exception $e) {                                           
     // Log error in error_log file.     
     trigger_error($e->getMessage() . mysql_error(), E_USER_WARNING);     
     // Send yourself an email.     
     error_log($e->getMessage() . "Date: " . date("l jS \of F, Y, h:i:s A") . ". File: " . $_SERVER['REQUEST_URI'], 1, "example@aol.com", "From: example@yahoo.com");
}
if(isset($result)) {
     blah blah blah ...
}

The problem is, I can receive a huge number of e-mails whenever there's a connection error.   How can I limit the number of e-mails that I send myself in the event that my database fails?   I really haven't a clue.   The only idea that I had was store the time that I sent the first e-mail in a database and then check the database before sending any other e-mails. But this obviously won't work because MySQL won't be working.   Any ideas will be much appreciated.

Hey guys, Im getting an undefined index limit in the whole code.

This is my code:

<?php
session_start();
$_SESSION['prev_page'] = $_SERVER['REQUEST_URI'];
if (!session_is_registered('username')) {
    header("location:login.php");

Im getting these errors and cant figure out at all how to fix them.

the reason is, is that you can set the limit of rows to show on one page, and that is set by the variable limit

it is used in 'localhost/admin?limit=5' That is 5 rows per page.

There is also one called 'localhost/admin?limit=all' that is to show all the rows in one page.

Im getting the errors:

Code: [Select]
Notice: Undefined index: limit in C:\Program Files (x86)\EasyPHP5.2.10\www\admin.php on line 176

I would be glad if someone could help me out by showing me how to set the limit when there is no GET used in the url.[/i]

Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved....

I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP?

I am in the midst of developing a web application and despite having a decent amount of experience in web development, I never really stopped and gave a ton of thought to memory when it comes to my php scripts. However, with this project I am using zend framework and it is a decent memory hog. So I have some questions...

I am monitoring my memory use for a typical call to my site and it appears as though its somewhere around 20MB. This seems like a ton and I am actively looking for ways to decrease it. One thing I noticed is that when I call zend's date class for the first time, my memory usage shoots up 3MB. However it is pretty much untouched for other instances of this class.

So if I do

Code: [Select]
echo(memory_get_usage());
        echo('<br />');
        $this->last_login=Zend_Date::now();
        echo(memory_get_usage());
        echo('<br />');
        $this->last_active=Zend_Date::now();
        echo(memory_get_usage());
        echo('<br />');

The result is Quote

9136448
12812408
12814496


So the jump is with that first call.

My question is, if two users are accessing the site at the same time, will they both experience that 3MB memory use? Or will the server have that class in memory so it only uses 3MB once?

Basically, if a call to the site uses 20MB of memory, will it be 20MB * the number of users. Or will the server have a lot of the information loaded into memory to subsequent calls so multiple users would use up far less memory then the initial?

I would assume the latter is the case based on the fact that reusing zend_date doesn't incur a 3MB hit every time. But without being admin of my server and hvaing tons of folks to test at once, its hard to tell.

Just how big can i make this ? Im sure it depends on the server hardware and if thats the case then how does one fidn out how big I can make this. I want to max it out.

Hi:

How do I set up an input textbox so that it remembers the text a user entered?

Code: [Select]
      <form name="form1" method="post" action="<?=$_SERVER['PHP_SELF']?>" >

I can't seem to figure it out

Hello Guys,
I wanted to know what is memory leakage? Where we have to takecare of ? How to avoid this thing?

I have this method that puts files into a zip file from an array list, it looks like this:
public function zip($files = array(), $maxMB = 2, $flag = ZIP_NEW){
$this->memory_size = $maxMB * 1024 * 1024;
$zip_id = $this->zip_id;
$this->zip[] = new ZipArchive();
$this->zip_id++;
if($flag == ZIP_NEW){
$open = $this->zip[$zip_id]->open("php://temp/maxmemory:$this->memory_size", ZipArchive::CREATE);
$files = (array)$files;
if(!empty($files)){
foreach($files as $file){
if(is_file($file)){
$this->zip[$zip_id]->addFile($file);
}
}
}
$this->zip[$zip_id]->close();
}
$this->function_name = __FUNCTION__;
return $this;
}

I then download them like this:
public function download($download_data, $download_name, $type = DOWNLOAD_FILE){
header("Pragma: public;");
header("Expires: 0;");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0;");
header("Content-Type: application/force-download;");
header("Content-Type: application/octet-stream;");
header("Content-Type: application/download;");
header("Content-Transfer-Encoding: binary;");
header("Content-Disposition: attachment; filename=$download_name;");
if($type == DOWNLOAD_FILE){
header("Content-Length: ".filesize($download_data).";");
if($download_data == PHP_MEMORY){
$handle = fopen(PHP_MEMORY."/maxmemory:$this->memory_size", 'r+');
echo stream_get_contents($handle);
}else{
readfile($download_data);
}
}elseif($type == DOWNLOAD_STRING){
header("Content-Length: ".mb_strlen($download_data).";");
echo $download_data;
}
$this->function_name = __FUNCTION__;
return $this;
}

When I run this code:
$files = array("file1.php","file2.php");
$live->zip($files)->download(PHP_MEMORY, "download.zip");

It downloads the file, the only problem is, is that when I open the file I get an error saying the file can not be opened. I know when I actually save it to a file instead of in memory it works. So, I am not sure if it isn't working in the download portion or the create file portion, as I have never worked with php://temp before. Any thoughts on why this doesn't work when using php://temp?
