Feature Request: new phpinfo_array() function

[bkdotcom]

Description

phpinfo() contains a fair amount of information that is only obtainable via phpinfo()

phpinfo() outputs as either plain-text or html depending on if called via CLI or web process

To obtain a value, one must wrap phpinfo in ob_start() and then parse the text or html that it returns, or extract the specific desired value(s)

A new phpinfo_array() function that returns the "raw" information would be helpful

return

array(
    INFO_GENERAL => array(
        'PHP Version' => '8.5.0-dev',
        'System' => string,
        'Build Date' => string,
        ...
        //  this license info is output as a "keyless" value as text/html... assigned to "info" here
        'info' => 'This program makes use of the Zend Scripting Language Engine:.... ',
    ),
    INFO_CREDITS => array(
        'PHP Group' => string,
        'Language Design & Concept' => string,
        'PHP Authors' => array(
            'Zend Scripting Language Engine' => string,
            'Extension Module API' => string,
            ...
        ),
        ...
    ),
    INFO_CONFIGURATION => array(
        'allow_url_fopen' => ['On', 'On'],
        ...
    ),
    INFO_MODULES => array(
        //    all module keys lowercase for consistancy
        'bcmath' => array(
            'BCMath support' => enabled,
            'bcmath.scale' => ['0', '0'],
            ...
         ),
        ...
        'phar' => array(
            'Phar: PHP Archive support' => 'enabled',
            ...
           // phar, xdebug, and others output "keyless" "information/license/disclaimer".   I've assigned to "info" here
            'info' => 'Phar based on pear/PHP_Archive, original concept by Davey Shafik. Phar fully realized by Gregory Beaver and Marcus Boerger. Portions of tar implementation Copyright (c) 2003-2009 Tim Kientzle.'
            ...
            'phar.cache_list' => [null, null], //   html and text output 'no value'
            ...
        ),
        'additional modules' => [], // list of lowercase strings 
    ),
    INFO_ENVIRONMENT => array(
        'TERM_PROGRAM' => string,
        ...
    ),
    INFO_VARIABLES => array(
         //   the values...    not the flattened /+print_r output that text/html gives
         '$_COOKIE' => array(),
         '$_SERVER' => array(),
         ....
    ),
    INFO_LICENSE => string,
)

If a single category flag is passed to phpinfo_array(), the topmost category level keys could be omitted

phpinfo_array(INFO_GENERAL)

return

array(
    'PHP Version' => '8.5.0-dev',
    'System' => string,
    'Build Date' => string,
    ...
),

What data are you interested in from phpinfo? Some of the critical ones are available as constants at runtime.

This would be a relatively big change, given phpinfo() is currently entirely hard-coded to print the given information in HTML or text form. I'm guessing the easier approach is if you elaborate which information is missing, so that it can be exposed as usual. (@NattyNarwhal beat me to it)

[bkdotcom]

In my current use-case I'm simply after the "Build Date" (output with phpinfo(INFO_GENERAL))
Noticed that most of the comments on phpinfo's documentation are poorly implemented parsers... that only parse the html output

to get build date:

\ob_start();
\phpinfo(INFO_GENERAL);
$phpInfo = \ob_get_clean();
$phpInfo = \strip_tags($phpInfo);
\preg_match('/Build Date (?:=> )?([^\n]*)/', $phpInfo, $matches);
$buildDate = $matches[1];

Nice to have:
$buildDate = phpinfo_array(INFO_GENERAL)['Build Date'];

[cmb69]

Nicer to have:

$buildDate = PHP_BUILD_DATE;

[bkdotcom]

On the topic of build date:

php -v

PHP 8.3.10 (cli) (built: Aug 1 2024 08:18:25) (NTS)

php -i | grep "Build Date"

Build Date => Aug 1 2024 08:16:34

^ 111 second discrepency

---

php -v

PHP 8.4.0-dev (cli) (built: Oct 18 2024 00:15:08) (NTS)

php -i | grep "Build Date"

Build Date => Oct 18 2024 00:13:23

^ 105 second discrepency

[NattyNarwhal]

I believe it's because it just uses __DATE__ and __TIME__, which are set for each translation unit separately. Since phpinfo lives in info.c and -v lives in main/main.c, if there's any disparity between when it compiles those files, it'll show up.

% git grep __DATE__  
Zend/zend_system_id.c:          PHP_MD5Update(&context, __DATE__, sizeof(__DATE__)-1);
ext/standard/info.c:            php_info_print_table_row(2, "Build Date", __DATE__ " " __TIME__);
main/main.c:            PHP_VERSION, sapi_module->name, __DATE__, __TIME__,

I agree with @cmb69 - good suggestion.
$buildDate = PHP_BUILD_DATE;

This def makes more sense.
