Re: Need help with php

I think you should post in the programming section designated for php coding you would probably get more hits. It is in the forum index underneath scripting languages.

Re: Need help with php

u must do something about ur programming concept. i meam, if u find this prog. to be tough then what about the tougher ones that are waiting for u in the near future.
to print the following format using for loop
13579
1357
135
13
1

u can take help of a nested loop
first start a for loop (say i) from (1 to c), where c=9, in the first case
and then inside that for loop create anothe for loop from (say j) (1 to i)
and now print j and outside the j loop print a new line and the decrease the value of c. i leave this on u. think by how much the value of c should be decrease to get the desired output.
best of luck!

Re: Need help with php

while we're on the topic of scripting languages, here's a dirty hack in python:

PHP Syntax (Toggle Plain Text)
l = []
for i in range(1,10):
    if i % 2 != 0:
        l.append(i)
for i in range(1,6)[::-1]:
    print "".join([str(x) for x in l[0:i]])
l = []
for i in range(1,10):
    if i % 2 != 0:
        l.append(i)
for i in range(1,6)[::-1]:
    print "".join([str(x) for x in l[0:i]])

Re: Need help with php

i'm not sure how my post is totally irrelevant. perhaps i shouldn't have said that we're on the "topic" of scripting languages, but instead that this is a thread in the c/c++ forum and i'm continuing with the off-forum-topic discussion.

anyways, that python code prints what you want. if you know python it will probably help you out when writing the php code.

Re: Need help with php

I think serfurj's post is completely on-topic, as it gives the OP an idea of how it's done in another language, so they're not being spoon-fed. Sounds like an excellent answer to me...
