Previous Comments: ------------------------------------------------------------------------ [2021-01-01 19:53:54] gkroll at keldine dot ca Description: ------------ When an array element is set to the value '' (it's empty), any attempt to access the value of that array element causes a nonsense error message: ERROR 8: Trying to access array offset on value of type bool Test script: --------------- $xyz = array ('a'=>'value1', 'b'=>'', 'c'=>'value3'); var_dump ($xyz); echo '<br />'; // let's see what we have if (isset($xyz['b'])) $foo = $xyz['b']; // no complaints here $foo = $xyz['b']; // this crashes echo 'foo is set to:', $foo, ': end', '<br />'; Expected result: ---------------- PHP 7.0 and earlier output: array(3) { ["a"]=> string(6) "value1" ["b"]=> string(0) "" ["c"]=> string(6) "value3" } foo is set to:: end I believe PHP 7.3 works too. Actual result: -------------- PHP 7.4 outputs: ERROR 8: Trying to access array offset on value of type bool ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80572&edit=1
