PHP 5.3.0 Added the optional parameter before_needle.
http://php.net/strstr

bonus: your $before_needle = "True"; is actually a string.
"False" != False. http://php.net/boolean

I know is a string, but also if write TRUE or true have the same error

I read more post that have same problem in a linux server, but in windows server work

What version of PHP are you using? The third parameter was not added until 5.3.0.

Thanks

I view now that my hosting not use 5.3.0 ( my hosting use 5.2.17, in local I have 5.3.14)

now how bypass this problem

I need to retrieved a string before "," and a string after ","

Assuming you have a comma only once in your string to search

Code:

$pos_comma = strpos($string_to_search, ',');
$before = substr($string_to_search, 0, $pos_comma - 1);
$after = substr($string_to_search, $pos_comma + 1);

will return everything before the comma (w/o the comma) and after the comma (again w/o the comma)

Edit: Actually this works for more than one comma in your string, but it will split the string according to the position of your first comma. Just to clarify

Or you could just

Code:

list($left_text, $right_text) = explode(',', $string);

Again, assuming 1 comma in your string...

No assumptions:

Code:

list($left_text, $right_text) = explode(',', $string, 2);

Another note - the original example shows this:

Code:

$before_needle = 'TRUE';

Which is wrong, it should be boolean.
