Question

My php script creates PDF on fly, the data comes from mysql db table it works fine till 30 records but more than that it says

http://code.google.com/p/dompdf/“rel=“nofollow”http://code.google.com/p/dompdf/。

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 56214 bytes) in F:xampphtdocswiseworkerdompdflibclass.pdf.php on line 3043

however I have used ini_set("memory_limit","96550M"); and also set in php.ini

; Maximum amount of memory a script may consume (5120MB)
; http://php.net/memory-limit
memory_limit = 96550M

我也增加了缓刑执行时间

if( !ini_get( safe_mode ) ){
        set_time_limit(0);
    }

但是,它仅将大约45个字节限制在65个字节上,如果我的片面表包含数百个记录,将会出现什么情况?

Answer 1

Ok感谢所有我都刚刚需要打上鸡场的记忆——限制=94G。 “连接被重新定位——与服务器的连接在上页装时重新开通。等......

在您的网页上使用:

 ini_set( max_execution_time , 3000);
 ini_set( memory_limit , 16M );

这种情形仅对您目前的文本有效。

Answer 3

45 bytes is not the limit - 33554432 is the limit, which is 32M. 45 bytes is just a block that PHP tried to allocate and failed (which is not very useful since it could be anything). Check that you are actually editing correct php.ini and it actually is reflected in your phpinfo(). 96550M btw is 94G of memory - do you really have that much? Try to unset objects you are not using and also try to run gc cycle via gc_collect_cycles (see: http://www.php.net/manual/en/function.gc-collect-cycles.php ) manually.

go through below code. update code and comment as per your requirement

<?php

    echo  <h1>System Configuration</h1> ;
    echo  <br> ;

    //PHP SETUP: all time in seconds

    //ini_set( max_execution_time , 18000);  // set your max execution time that you require for current script
    //ini_set( memory_limit ,  2048M ); //  set memory limit that you require for current script
    //ini_set("max_input_time",  5000 );
    //ini_set( default_socket_timeout ,  5000 );    
    //@set_time_limit(0);

    //DATABASE SETUP: all time in seconds
    //ini_set( mysql.connect_timeout ,  5000 );


    $ini_path       = php_ini_loaded_file();
    $ini_max_time   = ini_get( max_execution_time );
    $ini_memory     = ini_get( memory_limit );
