[SOLVED] explode with limit

[kev wood]

i want to know if the limit on the explode can be defined by a variable.  the code is normally written out in this way

 

$exploded_friends = explode(' ', $friends, 3);

 

what i want to know if it can be written out like this

 

$exploded_friends = explode(' ', $friends, $limit);

 

with $limit being set before the explode function has been executed.

Of course.

thanks for the reply i could not find a tutorial anywhere were the number was set in this way, i thought it is best checking befroe i begin coding.

i have just been looking at the examples again and some have the number inside [] and others do not which is the correct way to write this out.

Keep in mind that the variable is just a container holding a value

without the [] you would put a number or variable there just like any other argument.

sound nice one for that.  i was just unsure as some of the examples had them in with a number and some had them without and the number still there.

Are you referring to the square brackets like are shown here?

 

array explode ( string $delimiter , string $string [, int $limit ] )

 

If so, it's just the way that it is shown that a parameter is optional.
