The error message “Passing null to parameter #1 ($string) of type string is deprecated” is caused by passing a null value to the html_entity_decode() function where a string value is expected.<\/p>\n\n\n\n
To fix this error, you need to make sure that the value you pass to the html_entity_decode() function is not null. You can do this by checking the value before passing it to the function, like so:<\/p>\n\n\n\n
if ($string !== null) {\n $decoded_string = html_entity_decode($string);\n \/\/ Use $decoded_string as needed\n} else {\n \/\/ Handle the case where $string is null\n}<\/pre>\n\n\n\nAlternatively, you can use the null coalescing operator (??) to provide a default value if $string is null:<\/p>\n\n\n\n
$decoded_string = html_entity_decode($string ?? '');<\/pre>\n\n\n\nThis will set $decoded_string to an empty string if $string is null.<\/p>\n\n\n\n
In general, it’s a good practice to always check for null values before passing them to functions or using them in your code, to avoid similar errors.<\/p>\n\n\n\n
\n\n\n\nAnother Example:<\/h2>\n\n\n\n
Change<\/p>\n\n\n\n
html_entity_decode($string, ENT_QUOTES, 'UTF-8');<\/pre>\n\n\n\nto <\/p>\n\n\n\n
html_entity_decode($string ?? '', ENT_QUOTES, 'UTF-8');<\/pre>\n","protected":false},"excerpt":{"rendered":"The error message “Passing null to parameter #1 ($string) of type string is deprecated” is caused by passing a null value to the html_entity_decode() function where a string value is expected.
