I'm trying to create common masks from a string like so:
012abc.d+e_fg~hijk => 012{start}.d+{middle}_fg~{end}jk
replace:
$arrFromTo = array(
'st' => '{pre}',
'abc' => '{start}',
'e' => '{middle}',
'hi' => '{end}',
'dd' => '{post}'
);
Instead I keep overlapping replacements and get something like this instead (using a loop of str_replace
's):
012{{pre}art}.d+{mi{post}le}_fg~{end}jk
Because the st
is found in the already replaced {start}
and dd
is found in {middle}
.
How would you replace the following?
$str = 'abc.d+e_fg~hijk';
echo replace_vars($str); // Desired output: 012{start}.d+{middle}_fg~{end}kJ
