add to an integer variable after comparing two arrays - php

Question

I am fairly new to php. I am trying to update the score everytime I loop over this array. my code only works if the first value of the listbox was selected by the user and it gives a zero if its not selected. please help.
This is A.php
{
$SkillsArray = array();
$Score=0;
$SkillsArray = $_POST['DutiesDesc'];
//foreach($SkillsArray as $key =>$value )
{
$Sentence = $SkillsArray[0]." ".$SkillsArray[1]." ".$SkillsArray[2]." ".$SkillsArray[3]." ".$SkillsArray[4]." ".$SkillsArray[5]." ".$SkillsArray[6]." ".$SkillsArray[7 ]." ".$SkillsArray[8]." ".$SkillsArray[9]." ".$SkillsArray[10];
}
//Get the applicants score
for($i=0;$i<11;$i++)
{
if ($SkillsArray[$i] == $Text[$i])
{
$Score = $Score+$Val[$i];
}
}
} //**** The following is the HTML part of the code(form)
<form action = "A.php" method ="POST" enctype="multipart/form-data">
<label for="Position">Position:</label><input type="type" name="Position" size="35" /><br />
</p>
<p>
<!-- <label for="DutiesDesc">Duties Description: </label><textarea name="DutiesDesc" cols="30" rows="5" /></textarea>--> <br />
Job Description
<select name="DutiesDesc[]" size=5 multiple="multiple">
<option value="<?php echo $Arow['TextF1']?>"><?php echo $Arow['TextF1']?></option>
<option value="<?php echo $Arow['TextF2']?>"><?php echo $Arow['TextF2']?></option>
<option value="<?php echo $Arow['TextF3']?>"><?php echo $Arow['TextF3']?></option>
<option value="<?php echo $Arow['TextF4']?>"><?php echo $Arow['TextF4']?></option>
<option value="<?php echo $Arow['TextF5']?>"><?php echo $Arow['TextF5']?></option>
<option value="<?php echo $Arow['TextF6']?>"><?php echo $Arow['TextF6']?></option>
<option value="<?php echo $Arow['TextF7']?>"><?php echo $Arow['TextF7']?></option>
<option value="<?php echo $Arow['TextF8']?>"><?php echo $Arow['TextF8']?></option>
<option value="<?php echo $Arow['TextF9']?>"><?php echo $Arow['TextF9']?></option>
<option value="<?php echo $Arow['TextF10']?>"><?php echo $Arow['TextF10']?></option>
<option value="<?php echo $Arow['TextF11']?>"><?php echo $Arow['TextF11']?></option>
</select><br />

Answer 1

The values in the array $SkillsArray do not have the same index as your $Text array. If you select the 3rd (lets say the value is "c") and 5th (e.g. "e") item in your list, the array $SkillsArray will contain the following:
$SkillsArray[0] = "c";
$SkillsArray[1] = "e";
So what you need is a simple search over your $SkillsArray, since you can't rely on the indexes being conform with your $Text array.
if (is_array($SkillsArray)) {
for($i = 0; $i < count($Text); $i++) {
if (array_search($Text[$i], $SkillsArray) !== false) {
$Score += $Val[$i];
}
}
}
Please do remember to check, if $SkillsArray is indeed an array. If the user doesn't check any skills, the function array_search will return false for every item, which will result in the maximum score.

for($i=0;$i<11;$i++)
{
for($j=0;$j<11;$j++)
{
if (($SkillsArray[$i] == $Text[$j]))
{
$Score = $Score+$Val[$j];
}
}
This required a second loop in order to work properley:)
