Using data from a string

Using data from a string

<? 

// I wrote this function in response to someone's question on the PHP-DB mailing 
// list. What they wanted to do was get the output of a curl function and break it 
// up into variables that they can use. You can (if you want) specify the newline 
// separator as well as the the name/value separator. Default newline is '\n' and 
// default name/value separator is '='. 


header("Content-Type: text/plain"); 

$strText = "Name1=Value1 \n Name2 = Value 2\nName 3 =Value 3"; 

$arrPairs = extractPairs($strText); 

print_r($arrPairs); 



//Output: 


Array 
( 
     [Name1] => Value1 
     [Name2] => Value 2 
     [Name 3] => Value 3 
) 



//And here's the function you can use 

// this one splits with \n and = 
$arrPairs = extractPairs($strText); 

// this one splits with \n and -- 
$arrPairs = extractPairs($strText,"--"); 

// this one splits with <br> and --> 
$arrPairs = extractPairs($strText,"-->","<br>"); 


function extractPairs($strText,$strValueSeparator="=",$strNewlineSeparator="\n"){ 
     
    // kill the bad stuff... prevent a meaningless array 
    if (!is_string($strText)){ return array(""=>""); } 
     
    // gets rid of newlines/spaces etc so we don't get a crap array 
    $strText = trim($strText); 
     
    // separate each line in an element in an array 
    $arrLines = explode($strNewlineSeparator,$strText); 
     
    // loop through $arrLines, separating the 
    // names/values and placing them in $arrOutput 
    for ($i=0;$i<count($arrLines);$i++){ 
        $pos = strpos($arrLines[$i],$strValueSeparator);

        // and get rid of the whitespace b4 and after 
        $tempName = trim(substr($arrLines[$i],0,$pos)); 
        $tempValue = trim(substr($arrLines[$i],$pos+1)); 
         
        // if its all cool, chuck it on the array
