How can the use of double quotes in specifying image dimensions cause parsing errors in PHP scripts?

Using double quotes in specifying image dimensions can cause parsing errors in PHP scripts because PHP interprets the double quotes as string literals, which can lead to syntax errors when trying to use them for numerical values. To solve this issue, you can use single quotes or concatenate the dimensions with the dot operator to ensure that PHP recognizes them as numerical values. 

// Incorrect usage of double quotes for image dimensions
$imageWidth = "500";
$imageHeight = "300";

// Corrected usage of single quotes for image dimensions
$imageWidth = '500';
$imageHeight = '300';

// Alternatively, you can concatenate the dimensions with the dot operator
$imageWidth = 500;
$imageHeight = 300;
