    uopz_allow_exit — Allows control over disabled exit opcode

    Beschreibung

    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.

    Parameter-Liste

    allow

    Whether to allow the execution of exit opcodes or not.

    Rückgabewerte

    Es wird kein Wert zurückgegeben.

    Beispiele

    Beispiel #1 uopz_allow_exit() example

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

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    1

    Anmerkungen

    Achtung

    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.<?phpfunction 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:<?phpecho "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)
