    uopz_allow_exit — Allows 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

    例1 uopz_allow_exit() example

    <?php
    exit(1);
    echo     1;
    uopz_allow_exit(true);
    exit(    2);
    echo     2;
    ?>

    上の例の出力は以下となります。

    1

    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)
