PHP 致命错误:允许的内存大小 262144 字节已耗尽(尝试分配 21927 字节）

我对此有很大的问题，因为我无法理解其中的逻辑。我在 ubuntu 下运行 php，我正在尝试通过 php -q "script.php" 运行它

错误已打开

返回 $doc->saveXML（）;

在php中.ini该值为512M（我尝试了128M，-1,536870912,64M）

脚本告诉我"允许的内存大小为 262144 字节"......但是这个价值从哪里来？

这是我的 php 文件配置

我真的不明白发生了什么。

$doc = new DOMDocument();
$content = $doc->createElement("content");
$doc->appendChild($content);
$dataADDRowTop = $doc->createElement("RowInSQL");
$content->appendChild($dataADDRowTop);
...
return $doc->saveXML();

问题解决了。我已经重新安装了PHP，现在一切正常。

<?php
$content = '<?xml version="1.0" encoding="UTF-8"?>';
$content .= '<content>';
foreach ($rows as $row) {
    $content .= '<tag>'.$row.'</tag>';
}
$content .= '<content>';
return $content;
