So, just discovered what looks like a bug in the 'scl' wrapper with handling double-quote (at least) characters in command parameters. This is with:

scl-utils-20130529-19.el7.x86_64

Given the test scripts:

===============test.pl======================
#!/usr/bin/perl

print "SCL wrapper\n===============\n";

system(
       'scl',
       'enable',
       'rh-php72',
       '--',
       'php',
       'test.php',
       '"hello world"'
      );

system(
       'scl',
       'enable',
       'rh-php72',
       '--',
       'php',
       'test.php',
       'another"test'
      );

print "\nWithout wrapper\n===============\n";

system(
       '/opt/rh/rh-php72/root/bin/php',
       'test.php',
       '"hello world"'
      );

system(
       '/opt/rh/rh-php72/root/bin/php',
       'test.php',
       'another"test'
      );
===================================================

==============test.php==============================
<?php
print("\$argv:\n");
print_r($argv);
?>
===================================================

This is the rather unexpected output:

===================================================
$ ./test.pl
SCL wrapper
===============
$argv:
Array
(
    [0] => test.php
    [1] => hello
    [2] => world
)
/var/tmp/sclbhWRnY: line 8: unexpected EOF while looking for matching `"'
/var/tmp/sclbhWRnY: line 9: syntax error: unexpected end of file

Without wrapper
===============
$argv:
Array
(
    [0] => test.php
    [1] => "hello world"
)
$argv:
Array
(
    [0] => test.php
    [1] => another"test
)
=====================================================
