Bug #71188 [NEW]: str_replace converts integers in original $search array to strings
From: admin at supermartas dot cz
Operating system: Any
PHP version: 7.0.1
Package: Strings related
Bug Type: Bug
Bug description:str_replace converts integers in original $search array to strings
Description:
------------
If I try the test script on Windows 10 or (probably) on CentOS, I will
get this result:
array(3) {
[0]=>
int(0)
[1]=>
int(1)
[2]=>
int(2)
}
array(3) {
[0]=>
string(1) "0"
[1]=>
string(1) "1"
[2]=>
string(1) "2"
}
PHP converted all integers in $a array to strings but the original array
should stay untouched!
But it's even worse on Ubuntu 14.04.3 LTS (PHP Version
7.0.1-2+deb.sury.org~trusty+1) where it returns at first the same result
as on the other operating systems but after some page refreshes (press
F5 in your browser about 20 times) it returns:
array(3) {
[0]=>
string(1) "0"
[1]=>
string(875835694) "<br />
<b>Fatal error</b>: Allowed memory size of 134217728 bytes exhausted
(tried to allocate 3688507696953442304 bytes)
or sometimes:
array(3) {
[0]=>
string(1862275224) "<br />
<b>Fatal error</b>: Allowed memory size of 134217728 bytes exhausted
(tried to allocate 140065040769024 bytes)
In another script (where I found out there is something wrong with PHP)
it didn't throw that fatal error but it modified the $a array like this
(original $a array has 10 items):
array(10) {
[0]=>
string(5) "https"
[1]=>
string(5) "https"
[2]=>
string(0) ""
[3]=>
string(5) "15421"
[4]=>
string(5) "15421"
[5]=>
string(7) "CGI/1.1"
[6]=>
string(6) "HTTP/2"
[7]=>
string(6) "HTTP/2"
[8]=>
string(5) "close"
[9]=>
string(1) "0"
}
If I convert items of $a array to string by hand ($a = ["0", "1",
"2"]),
everything is working correctly.
Test script:
---------------
<?php
$a = [0, 1, 2];
$b = ["Nula", "Jedna", "Dva"];
var_dump($a);
str_replace($a, $b, "1");
var_dump($a);
Expected result:
----------------
array(3) {
[0]=>
int(0)
[1]=>
int(1)
[2]=>
int(2)
}
array(3) {
[0]=>
int(0)
[1]=>
int(1)
[2]=>
int(2)
}
Actual result:
--------------
array(3) {
[0]=>
int(0)
[1]=>
int(1)
[2]=>
int(2)
}
array(3) {
[0]=>
string(1) "0"
[1]=>
string(1) "1"
[2]=>
string(1) "2"
}
