php_ini_scanned_files

(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)

php_ini_scanned_files返回从额外 ini 目录里解析的 .ini 文件列表

说明

php_ini_scanned_files(): string|false

php_ini_scanned_files()php.ini 之后解析的配置文件的逗号分割列表。搜索的目录由编译时选项设置,也可以在运行时由环境变量设置:更多信息可以从安装指南中找到。

返回的配置文件包含完整路径。

参数

此函数没有参数。

返回值

成功时返回逗号分隔的 .ini 文件字符串。每个逗号后紧跟新的一行。如果未设置配置指令 --with-config-file-scan-dir 并且没有设置环境变量 PHP_INI_SCAN_DIR 将会返回 false。如果它设置了,并且目录是空的,将会返回一个空字符串。如果有未识别的文件,此文件也会进入返回的字符串,但是会导致一个 PHP 错误。此 PHP 错误即会在编译时出现也会在使用 php_ini_scanned_files() 函数时出现。

示例

示例 #1 列出返回的 ini 文件的简单示例

<?php
if ($filelist = php_ini_scanned_files()) {
if (
strlen($filelist) > 0) {
$files = explode(',', $filelist);

foreach (
$files as $file) {
echo
"<li>" . trim($file) . "</li>\n";
}
}
}
?>

<warning>

until i load more .ini files from <php-dir>/php.d/ as listed in phpinfo() (sections "Scan this dir for additional .ini files" and "Additional .ini files parsed"), php_ini_scanned_files() returns me NOTHING!

then i realized my php binary was not compiled with the "--with-config-file-scan-dir" option as listed in phpinfo() (section "Configure Command")

then i remembered the additional .ini files dir was set through the "PHP_INI_SCAN_DIR" system variable (new since php 5.2.0, see https://php.net/manual/en/configuration.file.php#configuration.file.scan)

until confusing and annoying, is the documented behavior... too bad now i don't know how to get the additional ini files purely with php functions (except "shell_exec()" maybe?)
