str_replace

[amos88]

hi!

I want to replace numbers from one array ($pattern) with numbers in a second array ($replace) whenever $pattern matches $subject.

$str = str_replace $pattern,$replace,$subject)

• this works fine as long as there are no small digits under 10 involved - as soon as this happens eg.: "102" is replaced as if it is a "1", "0" and "2".
  I already tried putting digits in the array in ' ', but it did not work ...

any idea about that ?

cheers

hello amos,

basically i'm not sure if str_replace can
provide what you want.
i think you also mixed up parameters:
str_replace expects:

$result = str_replace($what_to_find, $replace_with_this, $where_to_search_in);

hi

try this:

$what[0]="11";
$what[1]="2";
$what[2]="31";
$what[3]="4";
$what[4]="51";
$what[5]="6";
$what[6]="71";

$with[0]="a";
$with[1]="b";
$with[2]="c";
$with[3]="d";
$with[4]="e";
$with[5]="f";
$with[6]="g";

$where[0]="11";
$where[1]="21";
$where[2]="31";
$where[3]="41";
$where[4]="51";
$where[5]="61";
$where[6]="71";

$qc=count($what);
$ic=count($where);
for($i=0;$i<$ic;$i++)
{
for($q=0;$q<$qc;$q++)
{
if($where[$i]==$what[$q]) $where[$i]=$with[$q];
}
}
for($i=0;$i<$ic;$i++) echo $where[$i]."<br>";
