Function arguments involving references is following the trait of the C language. For those who knows the C language, the following example should shed some light on the behavior of PHP. struct _A { int value; }; void change_reference (struct _A* a) { a->value = 4; a = malloc(sizeof(struct _A)); // a becomes a local variable a->value = 5; } main () { struct _A* A = malloc(sizeof(struct _A)); A->value = 2; change_reference (A); printf("%d", A->value); // echo 4 (not 5) } ---- Server IP: 69.147.83.199 Probable Submitter: 193.49.30.34 ---- Manual Page -- http://php.net/manual/en/language.references.pass.php Edit -- https://master.php.net/note/edit/112323 Del: integrated -- https://master.php.net/note/delete/112323/integrated Del: useless -- https://master.php.net/note/delete/112323/useless Del: bad code -- https://master.php.net/note/delete/112323/bad+code Del: spam -- https://master.php.net/note/delete/112323/spam Del: non-english -- https://master.php.net/note/delete/112323/non-english Del: in docs -- https://master.php.net/note/delete/112323/in+docs Del: other reasons-- https://master.php.net/note/delete/112323 Reject -- https://master.php.net/note/reject/112323 Search -- https://master.php.net/manage/user-notes.php
