Foreach循环使用多个str_replace

Question

I have a foreach loop in a PHP script that outputs icons / links from a database. I've used this question to use str_replace to change some values after the icons are rendered.

foreach ($icons as $ic)
    { echo str_replace('{{EMP_NO}}', $_SESSION['EmpNo'], $ic['url']) . ' '; }

I need to do a similar operation on a value {{FIRST_NAME}} but when I append with a second str_replace the second command / value is ignored. Like this:

foreach ($icons as $ic)

    { echo str_replace('{{EMP_NO}}', $_SESSION['EmpNo'], $ic['url']) . ' '; }
    { echo str_replace('{{FIRST_NAME}}', $_SESSION['FirstName'], $ic['url']) . ' '; }

When I try to combine them like this it doubles the icons output which I don't want:

foreach ($icons as $ic) { echo str_replace('{{EMP_NO}}', $_SESSION['EmpNo'], $ic['url']) . ' '; echo str_replace('{{FIRST_NAME}}', $_SESSION['FirstName'], $ic['url']) . ' '; }

How do I also str_replace {{FIRST_NAME}}?

Answer 1

str_replace can replace array of values to array of other values:

foreach ($icons as $ic) {
    echo str_replace(
        array('{{EMP_NO}}', '{{FIRST_NAME}}'),
        array($_SESSION['EmpNo'], $_SESSION['FirstName']), 
        $ic['url']) . ' '
    );
}

And as already mentioned in @David's answer, though your code has a correct syntax, but its' logic is flawed.
