How to Remove Excessive Bunch of Characters From String Using PHP?
For example, I have the following string:
$description = '<p><span style="text-decoration: underline;"><strong>General</strong></span></p>
<p>Protecting all workers from possible injuries associated with encountering aggressive animals.</p>
<p> </p>
<p><span style="text-decoration: underline;"><strong>Application</strong></span></p>
<p>Employees must be vigilant in their awareness of potential animal encounters during field work.</p>
<p><strong> </strong></p>
<p><span style="text-decoration: underline;"><strong>Protective Mechanisms</strong></span></p>
<p>PPE</p>
<p>Specialized Equipment (i.e., bear bangers, bear spray, whistle or air horn)</p>
<p>Safe Work Practice</p>
<p><strong> </strong></p>
<p><span style="text-decoration: underline;"><strong>Selection and Use</strong></span></p>
<p>As per safe job requirements.</p>
<p>Location and/or land use.</p>
<p><strong> </strong></p>
<p><span style="text-decoration: underline;"><strong>Supervisor/Owner Responsibility</strong></span></p>
<ol>
<li>Identify jobs with potential encounters, and inform workers. Complete a hazard analysis prior to initiation of any site work. Complete ERP and review with workers.</li>
<li>Discuss procedures to prevent or avoid encounters.</li>
<li>Provide necessary equipment to prevent or influence the outcome of encounters.</li>
<li>Report all encounters to an appropriate authority (local Wildlife Officer).</li>
</ol>
<p><strong> </strong></p>
<p><span style="text-decoration: underline;"><strong>Worker Responsibility</strong></span></p>
<ol>
<li>Follow procedures developed to avoid encounters.</li>
<li>Make noise when moving through wooded areas.</li>
<li>Be aware of the preferred habitat for various wildlife.</li>
<li>Look and listen for animal activity (scat, grunts, and disturbed logs).</li>
<li>Carry Bear spray, bear bangers or an air horn.</li>
<li>Review the safe job procedures for using bear spray and bear bangers.</li>
<li>Avoid eye contact or moving towards an animal.</li>
<li>Back away slowly, facing animal (bear) stand tall, and make noise.</li>
<li>If necessary, climb a tree.</li>
<li>In pasture, be aware of livestock location when opening gates and moving through a field. If a bull is present, assess the safety of entering a field without a vehicle.</li>
<li>Leave an area if you feel uncomfortable or unsafe and <strong>report to supervision.</strong></li>
</ol>
<p> </p>
<p>Hazards: Dangerous wildlife can be defined as untamed animals of a predatory nature that have the ability to severely injure or kill people. Along with bears, this may also include stray dogs, aggravated moose, cougars, elk and deer, particularly during rutting season.</p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>
<p> </p>';
Is there a way to remove <p> </p> from the string if it appears consecutively (say more than 5 times in a row)?
I am looking for something like this:
$description = preg_replace("/<p> </p><p> </p><p> </p><p> </p><p> </p>+/", "", $description);
