Re: setting the same value to multiple variables

You could use variable variables with an array, like this:

$arr = array('readingGoalsEnjoymentLabelClass','readingGoalsInformationLabelClass',
    'readingGoalsAlphabeticLabelClass','readingGoalsPrintLabelClass',
    'readingGoalsPhonologicalLabelClass','readingGoalsPhoneticLabelClass',

'readingGoalsComprehensionLabelClass','readingGoalsVocabularyLabelClass',
    'readingGoalsInstructionsLabelClass','readingGoalsCriticalLabelClass',
    'readingGoalsCommunicateLabelClass');

foreach ($arr as $var) {
    ${$var} = 'class="errorHere"';
}

/* This is to check if it was done correctly. */
foreach ($arr as $var) {
    echo "$var = ${$var}\n";
}

Hi,

I'm sure this is quite basic. Nonetheless I'm new to PHP so I haven't figured it out.

I'd like to set each variable to the same value (without having to set that value individually for each variable).

Thanks for the help.


best,

Charles



if ( 1 == 1 )
{
$goodToGo = 0; $errorArray[] = "You must declare some goals on Activity 1.";


// this block of code does not set each variable to "class=\"errorHere\"";

$readingGoalsEnjoymentLabelClass && $readingGoalsInformationLabelClass && $readingGoalsAlphabeticLabelClass && $readingGoalsPrintLabelClass && $readingGoalsPhonologicalLabelClass && $readingGoalsPhoneticLabelClass && $readingGoalsComprehensionLabelClass && $readingGoalsVocabularyLabelClass && $readingGoalsInstructionsLabelClass && $readingGoalsCriticalLabelClass && $readingGoalsCommunicateLabelClass = "class=\"errorHere\"";
}
