About format storage of flexicontent fields

Please Can you explain the logic of how works the field flexicontent_fields_item_relations

What does the a: and the s: and the number against each

for example
a: 3: {s: 4: "link"; s: 24: " www.iseuan.ed.ao/ "; s: 5: "title"; s: 32: "Higher Institute of Nursing" ; s: 4: "hits", s: 0: "";}

Thanks

Please post such questions into new Forum thread and not to the thread about FC v2.0

I have splitted your topic into a new Forum thread.

When value of a field has multiple properties
e.g. weblink has URL, title, hits, etc then it is transform to a single "text" value via calling PHP serialize() on the array of the URL, title, hits, etc data.

to see the actual data:

still can not understand because a part is out a: 3: and another within {s: 4: "link"; s: 24: " www.iseuan.ed.ao/ "; s: 5: "title"; s: 32: "Higher Institute of Nursing" ; s: 4: "hits", s: 0: "";}
which defines the codes s: 4: ; s: 5:; s: 32:

referred to "a:" and to "s:"

excuse me misplaced thread

Regards,

The exact format of serialized data is no reason of concern , unless you want to un-serialize manually outside of PHP code.

About format, you could search the web or PHP website for information.

I understand:
for example s: 4: "link";
4 is four characters of link l(1) i(2) n (3) k (4)

s: 24: " www.iseuan.ed.ao/ ";
s: 24: is twenty four characters of " www.iseuan.ed.ao/ ";

what is the difference between extended weblink and weblink?
