PHP Fatal error: Allowed memory size of 134217728 bytes exhausted

Question

Hi I have an error that says "Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 40 bytes)".

Basically, in the php file I extract the information that the user chooses to do a search with the function I created in a package in an ORACLE data base. In php I call the function, pass in the parameters and display all the results.

<?php  
$db_connection = oci_connect('DBadmin', 'dbadmin', 'PETLOVERSDB');
if (!$db_connection) {
    $e = oci_error();
    trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}   

$type =  $_GET['type'];  
echo $type;

$result;
$resultArray;
$finalResult = ' ';

$sqlVariableFindMyPets = 'BEGIN :pet_variable := pet_search_package.pet_search_type(:p_type_data);END;';   
$result = oci_new_cursor($db_connection);     

$dataToReceive = oci_parse($db_connection, $sqlVariableFindMyPets);      

oci_bind_by_name($dataToReceive, ':pet_variable', $result, -1, OCI_B_CURSOR);  
oci_bind_by_name($dataToReceive, ':p_type_data', $type); 
oci_execute($dataToReceive); 
oci_execute($result, OCI_DEFAULT); 
oci_fetch_all($result, $resultArray, null, null, OCI_FETCHSTATEMENT_BY_ROW);


oci_close($db_connection);  

if($resultArray == null){
    echo "<h2>No results found<h2>";
} else { 
    foreach($resultArray as $iterator){
        $finalResult = $finalResult.'<div class="col-lg-4 col-sm-6"> 
                                        <div class="properties">

    }
    echo $finalResult;
}

?>

And the function in ORACLE is

CREATE OR REPLACE PACKAGE BODY pet_search_package AS
       FUNCTION pet_search_type(TYPEPET in VARCHAR2)
       RETURN SYS_REFCURSOR
       IS 
          pet_search_result SYS_REFCURSOR; 
          type_id NUMBER;

       BEGIN  

       select TP.pet_type_code into type_id
       from dbadmin.petType TP
       where TP.pet_type_name = TYPEPET;

    OPEN pet_search_result FOR select pet_type_name, pet_race_name, pet_cond_name, pet_energy_level, pet_learn_skill, vet_name, person_name, petlocation, petnotes, petabandondescription, pet_space, pet_treatment, pet_color, pet_sickness_name, pet_med_name
    from pet, pettype, petrace, petCondition, petSize,petEnergy, petlearningskill, veterinary, person, petSpace, pettreatments, petcolor, petsickness, petmedicine
    WHERE pettype.pet_type_code = type_id;
        RETURN pet_search_result; 

      EXCEPTION 
        WHEN NO_DATA_FOUND THEN 
          RETURN null;
      END; 

END pet_search_package;

I have tried putting ini_set('memory_limit', '-1'); on the php file but it doesn't seem to work. I also read that I have to increase variables ? which variables and where ? What can I do to solve this problem? Im not sure what is going on. Please, any suggestions would be appreciated !

PS. I tried the function on the database and works just fine

Answer 1

My guess is that you have a large table and your program fails while preparing the output.

instead of doing :

        foreach($resultArray as $iterator){
            $finalResult = $finalResult.'<div class="col-lg-4 col-sm-6"> 
                                            <div class="properties">
                                                <form action="pet-detail.php" method="POST">
                                                    <h4>'.$iterator['PET_TYPE_NAME'].' </h4>
                                                    <div class="image-holder"><img src="images/logo2.png" class="img-responsive" alt="properties"/></div>

                                            </div>
                                           </div>'; 
        }

So just display the results as you iterate through them. Your code will have a more efficient use of memory.
