[PHP] Re: setting the same value to multiple variables

[Eduardo Raúl Galván Sánchez]

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\"";
}
