split a string

[jianbo]

I tried to split a string with delimiter "|". Normally it works fine with explode, but if in this case: "|" is right near a number like "abc1990|na", I can't split it even with ascii code chr(124) instead of "|". How can I handle this situation?
Thanks.

I have used the pipe as delimiter in all different situations and have never run into a problem.

What does your code look like and what is the result?

 

[jianbo]

Try this. DRJ.
$str = "1^0^0^1999|n/a^knee pain";
$tmp = explode("|",$str);
or $tmp = explode(chr(124),$str) //124 is ascii code of "|"
you can't get what you want

jianbo:

This script:

<?php
print '<pre>';

$a = 'abc1990|na';

$b = split ('\|', $a);

print_r ($b);

$b = explode ('|', $a);

print_r ($b);

$b = preg_split ('/\|/', $a);

print_r ($b);
?>

Produces the following output on my machine:

Array
(
    [0] => abc1990
    [1] => na
)
Array
(
    [0] => abc1990
    [1] => na
)
Array
(
    [0] => abc1990
    [1] => na
)

The script you posted works fine for me.
I have no idea what it produces for you, but it works as expected.

Perhaps you have an old version of PHP? I'd suggest posting your output of

echo '<pre>';
print_r($tmp);

As well as your relevant system information... (OS, PHP Version)

(and that's a me too on code executes fine)

All, Thanks.
Sorry, I find the problem is not explode. I put a condition before explode. I use strpos("|",$str)>0 to check the existaance of "|", but it return false instead of a number.
Do you have idea about this?
Thanks again.

That would be because you have the parameters in the wrong order. See

God bless me. Sorry to waste your time. I think I am too tired. How can I make such low level mistake!

 

[sleipnir214]

Actually, it's a pretty understandable mistake. Most PHP functions similar to strpos() (explode(), split(), ereg(), preg_*()) take their input parameters in the order of "needle", "haystack". strpos() seems to be the weird one.
