How Can I use a function multiple times on the same page? - php

Question

Say this piece of code:
<?php while($user=mysqli_fetch_array($resultuser)){ ?>
<?php
function my_function($variable) {
//do something here...
}
?>
<?php };?>
This will obviously return this error
Cannot redeclare my_function() previously declared
So what if someone needs to use the same function multiple times across the same page? Is there a way to generate random function() names? Any idea how to get around this? Thanks.
EDIT WITH ACTUAL CODE
<?php while($deposit26=mysqli_fetch_array($resultdeposit26)){ ?>
<td data-th="Hours">
<?php
$week1hours = $deposit26['hours_worked'];
$week2hours = $deposit26['hours_worked_wk2'];
function time_to_decimal($time) {
$timeArr = explode(':', $time);
$decTime = ($timeArr[0] + ($timeArr[1]/60) + ($timeArr[2]/3600));
return $decTime;
}
$groupd26hours = time_to_decimal($week1hours) + time_to_decimal($week2hours);
echo round($groupd26hours, 2);
?>
</td>
<?php };?>

Answer 1

<?php
// Earlier in the file or included with include or require
function time_to_decimal($time) {
$timeArr = explode(':', $time);
$decTime = ($timeArr[0] + ($timeArr[1]/60) + ($timeArr[2]/3600));
return $decTime;
} ?>
...
<?php while($deposit26=mysqli_fetch_array($resultdeposit26)) : ?>
<td data-th="Hours">
<?php
$week1hours = $deposit26['hours_worked'];
$week2hours = $deposit26['hours_worked_wk2'];
$groupd26hours = time_to_decimal($week1hours) + time_to_decimal($week2hours);
echo round($groupd26hours, 2); ?>
</td>
<?php endwhile ?>

Answer 2

you want to declare the function outside the loop and call it inside
<?php
function my_function($variable) {
//do something here...
}
while($user=mysqli_fetch_array($resultuser)){
my_function($variable);
}?>

Answer 3

Let me try and explain what I think could help. I think a good starting point would be to look into including a script or including a script once in your files that require your function logic. That way multiple files can take advantage of the same logic without it having to be repeated. For example:
<?php
// File functions.php
function my_function($variable) {
...
}
?>
<?php
// File one
include_once "functions.php"
...
// Use my_function() from file one
my_function($var);
?>
<?php
// File two
include_once "functions.php"
...
// Use my_function() from file two
my_function($var);
?>
