replace and for together

[joane1]

help me please.

i have more strings as this one:

$stringA = "hello world, 354124";
$stringB = "her423rf43llo eewrd, 150024";
and so on...

I must to obtain this output:

from
somethings, somenumbers
to
text_to_replace N 0116474

PS
N = integer autoincrement (as in the for cycle).

How can i do? thanks 😉

i have several strings... as an array. Every string has this syntax:

somethings, somenumbers

They must become

text_to_replace 2 411312444
text_to_replace 3 555474
text_to_replace 4 33603657
text_to_replace 5 63657
....

i seen no relationship between:

$stringA = "hello world, 354124";
$stringB = "her423rf43llo eewrd, 150024";

and

text_to_replace 2 411312444
text_to_replace 3 555474
text_to_replace 4 33603657
text_to_replace 5 63657

i tried this code:

for ($i = 1; $i <= 10; $i++) {
$value = preg_replace("/[A-Za-z ]+/", "text_to_replace $i ", $strings);
echo $value . "<br />";
}

but it doesn't work fine.

From what you've said, the best interpretation I can do is that you want to create string consisting of
"text to replace "
followed by an incremented var
$i
followed by the trailing number of each input string
123546

Or, in other words, you want the trailing number from the input strings, and then append that to other stuff. As such, you do not need preg at all.

1. Explode your input strings on ', ' (comma whitespace) and the input number is in the second array element.
2. Concatenate 'text to replace ' . $i . $parts[1]
