IntelliJ Structural Search in PhpStorm to find specific function used within foreach block

Question

I need to find all foreach blocks wherever I have used current() function inside of it. Below is sample code block, which should get find.

$x=12;
foreach ($array as &$val)
{
    $cur=current($array);
    $x=$x+$cur;
    echo $cur;
}

You can try this:

foreach ($statement$) {
$st1$
$var$ = current($arr$);
$st2$
}

Test code:

<?php

$x=12;
foreach ($array as &$val)
{
    $cur=current($array);
    $x=$x+$cur;
    echo $cur;
}

foreach ($array as &$val)
{
    $cur=current($array);
}

foreach ($array as &$val) {
    $x=$x+$cur;

    $cur = current($array);
}

foreach ($array as &$val) {
    $x=$x+$cur;
    echo $cur;
    echo $cur;
    $cur = current($array);
}

foreach ($array as &$val) {
    $x=$x+$cur;
    echo $cur;
    echo $cur;
}

Result:

NOTES:

1. You can change Search target from "Complete match" to some specific placeholder/variable and it will highlight only that place instead of the whole foreach block...

2. That rule will not find places where current() is used without assignment or in a some different way (it has to be $someVar = current($someArray);).

   You may create a separate rule for that (I'm not sure right now how can they be merged together though), e.g.

foreach ($statement$) {
$st1$
current($arr$);
$st2$
}
