ldap_set_option($con, LDAP_OPT_X_TLS_REQUIRE_CERT, LDAP_OPT_X_TLS_NEVER);

Functions that take faulty parameters without notice in PHP7.4 but raise a type-error in PHP8
<?php
/**
* This file reads the previously created file and executes the listed function calls via eval.
* As eval throws up when something goes south I needed to exclude some calls, where pass-by-reference is used
* This script will then check whether a warning is raised or not and if not, add the function call to the file
* "problematicFunctionCalls" and the function itself to the "problematicFunctions" file.

Different Scopes for reading and writing properties
<?php
class Foo
{
// when there are two visibility declarations following one another
// the first one describes reading, the second one writing.
// If it's only one declaration it is used for reading *and* writing
// So this can be read publicly but only this class can write to the property.
