This problem has got me beat! I cant figure out how to insert a minus sign
into each element in an array of strings.
I keep getting the error that the first element in array_push has to be an
array, no matter what method I've tried, and I cant think of any more!
Im trying to isolate terms in polynommials, which Ive stored in an array m[]

like this:

\$m[0]="-3x_1^6/7-4x_2^3/5";
\$m[1]="-4x_3^2/3-7x_4/7";

/*Each element in m has two terms, and I want to isolate these by exploding
on the minus sign, thus giving me four elements, which then need to have a
minus inserted into them.

I take one of the four elements in \$ss, and for each character I push it
into a temporary storage array \$test, then I reverse \$test so the term is in

the correct order, and then I insert the minus sign at the start. But
funnily enough, there seems to be a flaw in my logic or code. What Ive
written so far is*/

\$ss=explode("-",\$m);

for(\$cnt=1;\$cnt<count(\$ss);\$cnt++)
{
for(\$waa=0;\$waa<\$cnt;\$c++)
{
array_push(\$test,\$ss[\$waa])
}
array_reverse(\$test);
array_push(\$test,"-");
array_push(\$real,\$test);

I would be extremely grateful for anyones assistance, thanks a million,

Regards

Bren
