let's say I want to return all chars after some needle char 'x'
from:
$source_str = "Tuex helo babe"
.
Normally I would do this:
if( ($x_pos = strpos($source_str, 'x')) !== FALSE )
$source_str = substr($source_str, $x_pos + 1);
Do you know a better/smarter (more elegant way) to do this?
Without using regexp that would not make it more elegant and probably also slower.
Unfortunately we can not do:
$source_str = substr(source_str, strpos(source_str, 'x') + 1);
Because when 'x'
is not found strpos
returns FALSE
(and not -1
like in JS).
FALSE
would evaluate to zero, and 1st char would be always cut off.
Thanks,
Your first approach is fine: Check whether x
is contained with strpos
and if so get anything after it with substr
.
But you could also use strstr
:
strstr($str, 'x')
But as this returns the substring beginning with x
, use substr
to get the part after x
:
if (($tmp = strstr($str, 'x')) !== false) {
$str = substr($tmp, 1);
}
But this is far more complicated. So use your strpos
approach instead.
