PHP Array last element being lost from using another array as dictionary - php

Question

I have three arrays. One that contains the given title information from the user stored in $attributenames. The second has the data from the user stored in $anesdata. (So the first two are related) And the third is a dictionary so that I can get out the information I want using the index which is stored in $medicalInstanceDictionary.
This is the first one:
Array
(
[0] => PATIENT MRN
[1] => PATIENT LAST NAME
[2] => PATIENT FIRST NAME
[3] => PATIENT MIDDLE NAME
[4] => PATIENT SSN
[5] => PATIENT SEX
[6] => INVOICE
[7] => TRANSACTION
[8] => DATE OF PROCEDURE
[9] => POSTING DATE
[10] => LOCATION
[11] => CHARGE AMT
[12] => PROVIDER
[13] => FSC1
[14] => FSC2
[15] => PATIENT DOB
[16] => ATTENDING SURGEON
[17] => ATTENDING SURGEON
[18] => CPT CODES
[19] => ASA CLASSFICATION
[20] => ANESTHESIA CRNA
[21] => ANESTHESIA RESIDENT
[22] => SURGERY START TIME
[23] => SURGERY END TIME
[24] => SVC UNIT
[25] => FACILITY NAME
[26] => BILLING NUMBER
[27] => BILLING AREA NAME
[28] => PROCEDURE MODIFIER1
[29] => PROCEDURE MODIFIER2
[30] => PROCEDURE MODIFIER3
[31] => PRIMARY DX
[32] => SECONDARY DX
)
The second array is a two dimensional array, but each line is equivalent to one patient. So that first patient looks like this(put in x's instead of actual patient data):
[0] => Array
(
[0] => xxxx
[1] => xxxx
[2] => xxxx
[3] => xxxx
[4] => xxxxx
[5] => xxxx
[6] => xxxx
[7] => xxx
[8] => xxxxx
[9] => xxxx
[10] => xxxx
[11] => xxxxx
[12] => xxxx
[13] => xxxxx
[14] => xxxx
[15] => xxxx
[16] => xxxxxxx
[17] => xxxxx
[18] => xxxxx
[19] => xxxx
[20] =>
[21] => xxxxx
[22] => xxxxx
[23] => xxxxx
[24] => xxxxx
[25] => xxxx
[26] => xxxxx
[27] => xxxx
[28] => xxxxxxxx
[29] => xxxx
[30] =>
[31] => xxxxxxx
[32] => xxxxxxx
)
Then the dictionary looks like this:
$medicalInstanceDictionary = array(
'CPT CODES' => "CPT_Code",
'ASA CLASSFICATION' => "MG_ASA_Class",
'FACILITY NAME' => "Facility_Name",
'BILLING NUMBER' => "Billing_Number",
'BILLING AREA NAME' => "Billing_Area_Name",
'PROCEDURE MODIFIER1' => "Procedure_Modifier1",
'PROCEDURE MODIFIER2' => "Procedure_Modifier2",
'PRIMARY DX' => "Primary_Dx",
'SECONDARY DX' => "Secondary_Dx",
'INVOICE' => "FIN"
);
I am doing a nested foreach loop to get each row.
foreach ($dataarray as $dataindex => $datavalue)
{
$out = "";
foreach ($dictionary as $index => $value)
{
//find PATIENT MRN in $attributearray and get it's index
$attributeindex = array_search($index, $attributearray);
if ($attributeindex===FALSE) {
echo "Error : ".$index." not found <br />";
} else {
echo "<br>The attribute is: ".$value." The index is: ".$attributeindex."<br>";
}
(more code....)
}
(more code....)
}
That echo statement looks like this:
The attribute is: CPT_Code The index is: 18
The attribute is: MG_ASA_Class The index is: 19
The attribute is: Facility_Name The index is: 25
The attribute is: Billing_Number The index is: 26
The attribute is: Billing_Area_Name The index is: 27
The attribute is: Procedure_Modifier1 The index is: 28
The attribute is: Procedure_Modifier2 The index is: 29
The attribute is: Primary_Dx The index is: 31
Error : SECONDARY DX not found
The attribute is: FIN The index is: 6
I have no idea why it is skipping over Secondary_Dx. I have checked for spelling errors. I don't think it is my method of doing it because it only does not work for Secondary_Dx. The only thing I can think of is that it does something funky since it is the last element of the array. Has anyone seen this before?
Edit:
Added element(tried both methods, and both resulted in the same looking array using print_r:
//array_push($attributenames, "THE END");
$attributenames[] ="THE END";
echo "<pre>";
print_r($attributenames);
echo "</pre>";
output from that along with the error handling statement from above:
Array
(
[0] => PATIENT MRN
[1] => PATIENT LAST NAME
[2] => PATIENT FIRST NAME
[3] => PATIENT MIDDLE NAME
[4] => PATIENT SSN
[5] => PATIENT SEX
[6] => INVOICE
[7] => TRANSACTION
[8] => DATE OF PROCEDURE
[9] => POSTING DATE
[10] => LOCATION
[11] => CHARGE AMT
[12] => PROVIDER
[13] => FSC1
[14] => FSC2
[15] => PATIENT DOB
[16] => ATTENDING SURGEON
[17] => ATTENDING SURGEON
[18] => CPT CODES
[19] => ASA CLASSFICATION
[20] => ANESTHESIA CRNA
[21] => ANESTHESIA RESIDENT
[22] => SURGERY START TIME
[23] => SURGERY END TIME
[24] => SVC UNIT
[25] => FACILITY NAME
[26] => BILLING NUMBER
[27] => BILLING AREA NAME
[28] => PROCEDURE MODIFIER1
[29] => PROCEDURE MODIFIER2
[30] => PROCEDURE MODIFIER3
[31] => PRIMARY DX
[32] => SECONDARY DX
[33] => THE END
)
This is dictionary array Array
(
[CPT CODES] => CPT_Code
[ASA CLASSFICATION] => MG_ASA_Class
[FACILITY NAME] => Facility_Name
[BILLING NUMBER] => Billing_Number
[BILLING AREA NAME] => Billing_Area_Name
[PROCEDURE MODIFIER1] => Procedure_Modifier1
[PROCEDURE MODIFIER2] => Procedure_Modifier2
[PRIMARY DX] => Primary_Dx
[SECONDARY DX] => Secondary_Dx
[INVOICE] => FIN
)
The attribute is: CPT_Code The index is: 18
The attribute is: MG_ASA_Class The index is: 19
The attribute is: Facility_Name The index is: 25
The attribute is: Billing_Number The index is: 26
The attribute is: Billing_Area_Name The index is: 27
The attribute is: Procedure_Modifier1 The index is: 28
The attribute is: Procedure_Modifier2 The index is: 29
The attribute is: Primary_Dx The index is: 31
Error : SECONDARY DX not found
Array ( [0] => PATIENT MRN [1] => PATIENT LAST NAME [2] => PATIENT FIRST NAME [3] => PATIENT MIDDLE NAME [4] => PATIENT SSN [5] => PATIENT SEX [6] => INVOICE [7] => TRANSACTION [8] => DATE OF PROCEDURE [9] => POSTING DATE [10] => LOCATION [11] => CHARGE AMT [12] => PROVIDER [13] => FSC1 [14] => FSC2 [15] => PATIENT DOB [16] => ATTENDING SURGEON [17] => ATTENDING SURGEON [18] => CPT CODES [19] => ASA CLASSFICATION [20] => ANESTHESIA CRNA [21] => ANESTHESIA RESIDENT [22] => SURGERY START TIME [23] => SURGERY END TIME [24] => SVC UNIT [25] => FACILITY NAME [26] => BILLING NUMBER [27] => BILLING AREA NAME [28] => PROCEDURE MODIFIER1 [29] => PROCEDURE MODIFIER2 [30] => PROCEDURE MODIFIER3 [31] => PRIMARY DX [32] => SECONDARY DX [33] => THE END )

The attribute is: FIN The index is: 6

Answer 1

You should test for a valid $attributeindex !
$attributeindex = array_search($index, $attributearray);
if ($attributeindex===FALSE) {
echo "Error : ".$index." not found <br />";
} else {
echo "<br>The attribute is: ".$value." The index is: ".$attributeindex."<br>";
}
If you get a not found Error you can be shure $index is not found in $attributearray .
Update :
This is very strange !
From your output we can clearly see.
$index == SECONDARY DX
and
$attributearray has a key [32]
[32] => SECONDARY DX
Only to test :
can you add to $attributearray at the end
[33] => 'END'
and see what happens.
Update 2 :
As i can see in the new output you got with
echo "<pre>";
print_r($attributenames);
echo "</pre>";
There is a empty line between [32] and [33].
There must be a invisible sign at the end of [32] => SECONDARY DX
I suspect a new line character.
Array
(
[0] => PATIENT MRN
[1] => PATIENT LAST NAME
....
[30] => PROCEDURE MODIFIER3
[31] => PRIMARY DX
[32] => SECONDARY DX
[33] => THE END
)
Try to remove that character and it should work .
TIP:
If you ever re experiencing similar behavior, you should check with :
for example:
echo bin2hex($attributenames[32]);
Output in windows look at the end :
5345434f4e444152592044580d0a
Where 0d is CR = Carriage return and 0a is LF = Line feed .

Answer 2

Try using trim() on the value you are testing for. If there is white space you can't see at the end it won't match.
$attributeindex = trim( array_search($index, $attributearray) );
