If like me you thought ini_restore() would restore to the most recent setting rather than the startup value, you could use this.
<?php
/**
* Executes a function using a custom PHP configuration.
*
* @param array $settings A map<ini setting name, ini setting value>.
* @param callable $doThis The code to execute using the given settings.
* @return mixed Returns the value returned by the given callable.
*/
function ini_using_do(array $settings, callable $doThis){
foreach($settings as $name => $value){
$previousSettings[$name] = ini_set($name, $value);
}
$returnValue = $doThis();
if(isset($previousSettings)){
foreach($previousSettings as $name => $value){
ini_set($name, $value);
}
}
return $returnValue;
}
?>
