嗨我有一个错误，上面写着“致命错误：允许的内存大小为134217728字节耗尽（试图分配40个字节）”。

基本上，在php文件中，我提取用户选择使用我在ORACLE数据库中的包中创建的函数进行搜索的信息。在php中我调用函数，传入参数并显示所有结果。 

<?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">

    }

?>

ORACLE中的函数是

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;

我已经尝试将ini_set('memory_limit', '-1');放在php文件上但它似乎不起作用。我还读到我必须增加变量？哪个变量和哪里？我该怎么做才能解决这个问题？我不知道发生了什么事。请，任何建议将不胜感激！

PS。我在数据库上尝试了这个功能并且运行得很好

我的猜测是你有一个大表，你的程序在准备输出时失败。

而不是：

        foreach($resultArray as $iterator){
            $finalResult = $finalResult.'<div class="col-lg-4 col-sm-6"> 
                                            <div class="properties">

        }
        echo $finalResult;

试试这个foreach循环：

        foreach($resultArray as $iterator){
            echo '<div class="col-lg-4 col-sm-6"> 
                                            <div class="properties">
                                                <form action="pet-detail.php" method="POST">
                                                    <h4>'.$iterator['PET_TYPE_NAME'].' </h4>
                                                    <div class="image-holder"><img src="images/logo2.png" class="img-responsive" alt="properties"/></div>
                                                    <h5>'.$iterator['PET_RACE_NAME'].' </h5> 
                                                    <h5>'.$iterator['PET_COLOR'].' </h5>

                                                </form>
                                            </div>
                                           </div>'; 
        }

所以只需在迭代它们时显示结果。您的代码将更有效地使用内存。
