replace one time

[dotJoon]

$myVar="abcd ABCD abcd";

$myVar1=str_ireplace("b", "",$myVar);

result1

acd ACD acd

$myVar2=str_replace("b", "",$myVar);

result2

acd ABCD acd

The code above prouduces the result above.

I like to replace "b" just one time.
The would-be code below doesn't work correctly, but I hope it show what I want.

would-be code

$myVar3=str_ireplace("b", "",$myVar, 1);

target result

acd ABCD abcd

How can I get my target result above?

You can use strpos then do a substr_replace

[dotJoon]

The following trials seems not to work.

trial1
 
substr_replace(2, $myVar)

trial2
 
substr_replace("b", $myVar,2)

<?php
$string = 'abcdef abcdef abcdef';


if(false !== ($index = strpos($string, 'b'))){
	$string[$index] = null;
}


echo $string;
