php select specific content from input file to put in array elements - php

Question

I have an input file (exert from file shown below) with multiple lines that I need to select specific text from and put each selection into an array element:
exert from input file:
"BLOCK","PARTNO"
"ELEMENT","HEADER-"
"NAME","1AB000072186"
"REVISION","0000"
"PARTSHAPE","RECT_074_044_030"
"PACKAGE","120830E"
"PMABAR",""
"PARTCOMMENT","CAP-TANT*150uF*20%*10V7343*4.3mm"
"ELEMENT","PRTIDDT-"
"PMAPP",1
"PMADC",2
"ComponentQty",2
"BLOCK","PARTNO"
"ELEMENT","HEADER-"
"NAME","1AB030430005"
"REVISION","0000"
"PARTSHAPE","RECT_072_042_030"
"PACKAGE","120830E"
"PMABAR",""
"PARTCOMMENT","1.0000 Amp SUBMINIATURE FUSE"
"ELEMENT","PRTIDDT-"
"PMAPP",2
"PMADC",0
"ComponentQty",1
"BLOCK","PARTNO"
"ELEMENT","HEADER-"
"NAME","1AB030430001"
"REVISION","0000"
"PARTSHAPE","RECT_072_042_030"
"PACKAGE","120830E"
"PMABAR",""
"PARTCOMMENT","2.0000 Amp SUBMINIATURE FUSE"
"ELEMENT","PRTIDDT-"
"PMAPP",2
"PMADC",0
"ComponentQty",1
Notice that after each occurrence of the line with the phrase "ComponentQty" the content begins repeating...
Where I need the PartNumber that is next to the occurrence of "NAME" in one dimension of the array element and the content next to the occurrence of "PARTSHAPE" in the second dimension for each element. I am very confused on how to do this though...please help!!!

Answer 1

$fh = fopen('yourfile.txt', 'rb');
$found_stuff = array();
$last_component = null;
while($line = fgets($fh)) { // read a line
$parts = explode(',', $line); // split into components
switch($parts[0]) { // based on which key we're on
case '"NAME"':
$last_component = $parts[1]; // save the key's value
break;
case '"PARTSHAPE"':
$found_stuff[$last_component] = $parts[1]; // store the partshape name
break;
}
}
fclose($fh);
This should do the basic work. Read a line, explode it into pieces where commas occur. The first part will be the "key", the second part will be the value. Then simply keep reading until we either hit a NAME or a PARTSHAPE key, then store the values as appropriate.
Note that I've not stripped the double-quotes off the values. That's left as an exercise to the reader. This code also assumes that the file's format is regular and that a "NAME" will show up before any PARTSHAPE lines, and there'll be a perfect 1:1 alternation between NAME/PARTSHAPE lines. If you get two PARTSHAPES in a row, you'll lose the first one. And if a PARTSHAPE shows up before the first NAME is encounted, you'll sorta lose that one too.

Answer 2

The following steps worked for me:
The section pasted in my OP (repeating many times more) is defined as $PartNoContents
and $BlockData[] is the array that I need to paste selections from $PartNoContents into.
$PartNoContents = str_replace('"', '', $PartNoContents);
$PartLines = explode("\n", $PartNoContents);
$PartData = array();
foreach ($PartLines as $PartLine){
$PartData[] = explode(',', $PartLine);
}
for($p=0;$p<count($PartLines);$p++){
if ( isset( $PartData[$p][1] ) && !empty( $PartData[$p][1] ) ){
$p1 = str_replace(chr(13), '', $PartData[$p][1]);
if ( isset($BlockData[$b][0]) && !empty($BlockData[$b][0]) && $BlockData[$b][7]==$p1 ){
$BlockData[$b][13] = str_replace(chr(13), '', $PartData[$p+$PartDataIncNum][1]);
$p = count($PartLines) ;
}
}
}
