All,
I want to clean up my PHP.ini file on production to be as streamlined as
possible so that it's easier to work with and maintain. It is easier to
do a diff of my INI and the recommended INI if both files are very
similar with whitespace removed, comments cleaned out, and keys sorted,
etc. I've tried to use parse_ini_file() function to parse the INI file,
but that won't work because the 'extension = *' key is used multiple
times in the php.ini. parse_ini_file assumes unique assoc array is
returned.
I'm guessing PHP doesn't actually use the parse_ini_file to read its own
ini.
So, I then started parsing the ini myself with my own custom code and
soon realized that PHP might not be using the [section] tags either as
it uses the INI key=values. Seems like the [section] tags are used more
like suggestions for key grouping than for anything functional. Is this
a correct assumption? If so, I've got the following INI reading code
which will munch the php.ini-recommended and output just the strings
which are not commented out.
See here and let me know if this looks like robust code:
//----------------------------------------------------------------------
#!/usr/bin/php
<?php
// we pass the name of an INI file on the command line
$script = array_shift($argv);
$ini_file_name = array_shift($argv);
if (!$ini_file_name || !file_exists($ini_file_name)) {
die("usage: $script <php.ini file>\n");
}
// slurp in the whole ini file and init
$lines = file($ini_file_name);
$data = array();
foreach ($lines as $line) {
// remove trailing comments, newlines, and start/end whitespace
$line = trim(preg_replace("/;[^\"\']*$/", "", trim($line)));
// skip blank lines, commented lines, ini sections, or anything
without an '=' in the line
if (!$line || $line{0} === ';' || $line{0} === '[' || strpos($line,
'=') < 1) {
continue;
}
// fix spacing between equal sign
list ($key, $value) = preg_split("/\s*=\s*/", $line, 2);
$line = "$key = $value";
// save this key=value pair
array_push($data, $line);
}
// sort and print all keys
sort($data);
print join("\n", $data);
?>
//----------------------------------------------------------------------
