uopz_allow_exitAllows control over disabled exit opcode

説明

uopz_allow_exit(bool $allow): void

By default uopz disables the exit opcode, so exit() calls are practically ignored. uopz_allow_exit() allows to control this behavior.

パラメータ

allow

Whether to allow the execution of exit opcodes or not.

戻り値

値を返しません。

例1 uopz_allow_exit() example

uopz_allow_exit(true);
exit(

echo
2;
?>

上の例の出力は以下となります。

注意

警告

OPcache optimizes away dead code after unconditional exit.

PHP 8.4 changed exit and die to functions, so this call has no effect. Instead you can redefine those functions to do nothing.

<?php
function allow_exit( bool $allow ) {
if (
PHP_VERSION_ID < 80400 ) {
uopz_allow_exit( $allow );
} elseif (
$allow ) {
uopz_unset_return( 'exit' );
uopz_unset_return( 'die' );
} else {
uopz_set_return('exit', static function() {});
uopz_set_return('die', static function() {});
}
}
?>

Test:
<?php
echo "Calling die() with allow_exit(false)\n";
allow_exit( false );
die();
echo
"Calling die() with allow_exit(true)\n";
allow_exit( true );
die();
echo
"Unreachable\n";
?>
Calling die() with allow_exit(false)
Calling die() with allow_exit(true)
